After updating to FF8 it has become extremely buggy.

FF freezes when trying to change tabs. Timed it last night and it takes 10-12 seconds to switch tabs. When I try to open a new tab by clicking on the '+' sign it opens a new browser instead(not always). FF has bugun using exteme amounts of system resources. Sometimes half of everything. Disabled plugins and same thing. Extremely slow opeing web pages also. Using Win7 Ultimate on a 64bit system. Anything?

Try the Firefox SafeMode to see how it works there. <br />
''A troubleshooting mode, which disables most Add-ons.'' <br />
''(If you're not using it, switch to the Default Theme.)''
* You can open the Firefox 4.0+ SafeMode by holding the '''Shft''' key when you use the Firefox desktop or Start menu shortcut.
* Or use the Help menu item, click on '''Restart with Add-ons Disabled...''' while Firefox is running. <br />
''Don't select anything right now, just use "Continue in SafeMode."''
''To exit the Firefox Safe Mode, just close Firefox and wait a few seconds before using the Firefox shortcut (without the Shft key) to open it again.''
'''''If it is good in the Firefox SafeMode''''', your problem is probably caused by an extension, and you need to figure out which one. <br />

After loading Snow Leopard, Firefox has become extremely slow. I have reload FF but no help. Suggestons?

After loading Snow Leopard, FF is extremely slow loading web pages. I have uninstalled and reinstalled FF but this did not help. Any suggestions?

It's possible that you are having a problem with some Firefox add-on that is hindering your Firefox's normal behavior. Have you tried disabling all add-ons (just to check), to see if Firefox goes back to normal?
Whenever you have a problem with Firefox, whatever it is, you should make sure it's not caused by one (or more than one) of your installed add-ons, be it an extension, a theme or a plugin. To do that easily and cleanly, run Firefox in [http://support.mozilla.com/en-US/kb/Safe+Mode safe mode] (don't forget to select ''Disable all add-ons'' when you start safe mode). If the problem disappears, you know it's from an add-on. Disable them all in normal mode, and enable them one at a time until you find the source of the problem. See [http://support.mozilla.com/en-US/kb/Troubleshooting+extensions+and+themes this article] for information about troubleshooting extensions and themes and [https://support.mozilla.com/en-US/kb/Troubleshooting+plugins this one] for plugins.
If you need support for one of your add-ons, you'll have to contact its author.
If the problem does not disappear when all add-ons are disabled, please tell me, so we can work from there. Please have no fear of following my instructions to the line, as all can be easily undone.

LONG LIVE ARCH~!!!!! Hek yeah I enjoy, especially since I was a major power user of XP & strictly XP. There was everything I ever needed. The only thing was that, if there was an Open-Source alternative, I would take it. I didn't know much about Linux other than that it ran EXTREMELY well as a server just as FreeBSD does. Once I finally took the time to google Linux, read about ditributions,open source and read blogs and read community comments etc.. I was like" I gotta be apart of this~!!" because XP was the shizz.

Things You Can Do To Keep Your Computer From Slowing Down
If your computer seems to be running slower here are some things you can do:
Boot into Safe Mode then repair your hard drive and permissions:
Repair the Hard Drive and Permissions Pre-Lion
Boot from your OS X Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.
If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
Repair the Hard Drive - Lion
Boot from your Lion Recovery HD. When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported, then click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu. Select Restart from the Apple menu.
Boot to the Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Restart your computer normally and see if this has helped any. Next do some maintenance:
Suggestions for OS X Maintenance
For situations Disk Utility cannot handle the best third-party utility is Disk Warrior; DW only fixes problems with the disk directory, but most disk problems are caused by directory corruption; Disk Warrior 4.x is now Intel Mac compatible.
OS X performs certain maintenance functions that are scheduled to occur on a daily, weekly, or monthly period. The maintenance scripts run in the early AM only if the computer is turned on 24/7 (no sleep.) If this isn't the case, then an excellent solution is to download and install a shareware utility such as Macaroni, JAW PseudoAnacron, or Anacron that will automate the maintenance activity regardless of whether the computer is turned off or asleep. Dependence upon third-party utilities to run the periodic maintenance scripts was significantly reduced since Tiger. These utilities have limited or no functionality with Snow Leopard or Lion and should not be installed.
OS X automatically defragments files less than 20 MBs in size, so unless you have a disk full of very large files there's little need for defragmenting the hard drive. As for virus protection there are few if any such animals affecting OS X. You can protect the computer easily using the freeware Open Source virus protection software ClamXAV. Personally I would avoid most commercial anti-virus software because of their potential for causing problems. For more about malware see Macintosh Virus Guide.
I would also recommend downloading a utility such as TinkerTool System, OnyX 2.4.3, or Cocktail 5.1.1 that you can use for periodic maintenance such as removing old log files and archives, clearing caches, etc.
For emergency repairs install the freeware utility Applejack. If you cannot start up in OS X, you may be able to start in single-user mode from which you can run Applejack to do a whole set of repair and maintenance routines from the command line. Note that AppleJack 1.5 is required for Leopard. AppleJack 1.6 is compatible with Snow Leopard. There is no confirmation that this version also works with Lion.
When you install any new system software or updates be sure to repair the hard drive and permissions beforehand.
Get an external Firewire drive at least equal in size to the internal hard drive and make (and maintain) a bootable clone/backup. You can make a bootable clone using the Restore option of Disk Utility. You can also make and maintain clones with good backup software. My personal recommendations are (order is not significant):
Carbon Copy Cloner
Data Backup
Deja Vu
SuperDuper!
SyncTwoFolders
Synk Pro
Synk Standard
Tri-Backup
Visit The XLab FAQs and read the FAQs on maintenance, optimization, virus protection, and backup and restore.
Additional suggestions will be found in Mac maintenance Quick Assist.
Referenced software can be found at CNet Downloads or MacUpdate.
Additional Hints
Be sure you have an adequate amount of RAM installed for the number of applications you run concurrently. Be sure you leave a minimum of 10% of the hard drive's capacity as free space.
Add more RAM. If your computer has less than 2 GBs of RAM and you are using OS X Leopard or later, then you can do with more RAM. Snow Leopard and Lion work much better with 4 GBs of RAM than their system minimums. The more concurrent applications you tend to use the more RAM you should have.
Always maintain at least 15 GBs or 10% of your hard drive's capacity as free space, whichever is greater. OS X is frequently accessing your hard drive, so providing adequate free space will keep things from slowing down.
Check for applications that may be hogging the CPU:
Open Activity Monitor in the Utilities folder. Select All Processes from the Processes dropdown menu. Click twice on the CPU% column header to display in descending order. If you find a process using a large amount of CPU time, then select the process and click on the Quit icon in the toolbar. Click on the Force Quit button to kill the process. See if that helps. Be sure to note the name of the runaway process so you can track down the cause of the problem.
Often this problem occurs because of a corrupted cache or preferences file or an attempt to write to a corrupted log file.

My iphone 4 has become extremely sensitive i cant talk on the phone without putting calls on hold, mute or hanging up!! when i'm in a call it's like the screen has become super sensitive to touch! I tried putting a screen protecter but didnt work pls help

My iphone 4 has become extremely sensitive i cant talk on the phone without putting calls on hold, mute or hanging up!! when i'm in a call it's like the screen has become super sensitive to touch! I tried putting on a screen protecter but this didnt work please help?

While on a call, the iPhone display should go black when lifted to your ear. Is this not happening or only happening intermittently?
Have you tried making calls without your silicone case on? Does this make any difference?
You could try updating or restoring the software to try to rule that out as a cause. If the issue remains after restoring then the issue is probably hardware related and may need to be serviced.

TS3276 hi after updating to Mountain Lion, it becomes difficult to quit Mail, always have to Force Quit. And while Mail is on standby, the fan keeps on running full power, the laptop is hot. Why is this happening?

hi after updating to Mountain Lion, it becomes difficult to quit Mail, always have to Force Quit. And while Mail is on standby, the fan keeps on running full power, the laptop is hot. Why is this happening?

If your computer was hot it wasn't asleep - it either didn't go to sleep or it work up after you put it to sleep. I've seen both things happen. First, read this article and follow the instructions.
1) For the next few days/weeks pay attention to the blinking light on the front of your computer when you close the lid. Don't put the computer into your backpack/case until it begins to blink. Wait a minute or so after it starts to blink to make sure it doesn't stop blinking - the signal it woke back up.
2) having followed the above instructions, if you take the computer out and it is hot again or if you take it out and discover it has powered down (you'll know this because when it starts up the battery will be drained and you'll see a progress bar over a ghostly display that will eventually become normal) immediately start the Console program and perform a search on 'sleep' and then 'wake'. This should bring up all the recent log files about sleep state changes (going to sleep and waking up). You should see one for when you put the computer to sleep and put it away and the next one should be just after you got it out. You'll find at least one though that shouldn't be there. That will tell you when the computer work up (when it shouldn't have) and might give a clue as to why.
One of the whys could be a magnet that is making the computer think the lid has been opened.

Syncing has become extremely slow with iOS 5.

After install of iOS 5, syncing from my PC to my iPhone 4 has become extremely slow. I've uninstalled iTunes, and restored my iPhone 4.
Anyone have a solution?
(by "slow" I mean I've been working on it for 16 hrs. Still not done.)

I did two things that made syncing an iPhone 4 with iOS5 a lot more speedier; not sure which did the trick but my iPhone now syncs in seconds rather than churn on and on and on. Here's what I did. First, in iTunes, under Edit, Preference, Devices, I checked the "Prevent iPods, iPhones, and iPads from syncing automatically". Second, I deleted all my old iPhone backups. After doing these two things, my iPhone 4 with iOS5 in iTunes 10.5 syncs in seconds.

My imac has become extremely slow

Hi, I have a 4 year old 27 inch imac, running 10.10.3; it has become extremely slow to boot up, to open apps and to get online. I'm a fairly heavy user of dropbox, and I am wondering if that is the issue -- other than that I run very run of the mill apps -- itunes, word/ppt/excel/, ical, imessage, firefox and safari, adobi acrobat, some use of iphoto. Suggestions?

Hi Old Toad -- this is what I got on Etrecheck:

My iPad has become extremely touchy in typing, particularly in Mail. Is there a clean-out for this?

iPad 6.1.3
For about the past week, my iPad has become extremely touchy to type on, especially in Mail. It inserts periods (the short-cut of hitting the space bar twice to put in a period), capitalizes letters, and inserts extra spaces. I type fast, but even when I type slowly, this happens. It's at the point now, where I prefer to use my iPod Touch or my iPhone for anything other than just looking something up. And sometimes, it back spaces and erases everything I've typed before I can stop it! If I quickly tap the screen it usually stops, but not before it has "automatically" erased some of my typing. Is there an app for mobile devices that can clean them out and find glitches, and maybe solve a problem like this?
I've been wondering if there is a clean-up app for mobile devices. I use a anti-virus program on my iMac, as well as an anti-spyware program. The anti-virus runs constantly; the anti-spyware program I run once a week. But there doesn't appear to be anything like this, or Clean My Mac (2) for mobile devices. I don't think Clean My Drive was intended for mobile devices. I don't know if it would solve this problem anyway.
Is there a solution for this, other than trotting my iPad down the road to my local Apple store 22 miles south? Thanks for any advice. alice d gray

First thing to try is to reset your device. Press and hold the Home and Sleep buttons simultaneously ignoring the red slider should one appear until the Apple logo appears. Let go of the buttons and let the device restart. See if that fixes your problem.

Dear.. I have recently installed Mavarick software and after installing it my menu has become less responsive.. the icons which used to slide fast now just drags hard.. pl suggest

Dear I have recently updated the free software version of OS Mavericks and after installing it my menu bar has become less responsive.

Please read this whole message before doing anything.
This procedure is a diagnostic test. It won’t solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
The purpose of this test is to determine whether the problem is localized to your user account. Enable guest logins* and log in as Guest. Don't use the Safari-only “Guest User” login created by “Find My Mac.”
While logged in as Guest, you won’t have access to any of your personal files or settings. Applications will behave as if you were running them for the first time. Don’t be alarmed by this; it’s normal. If you need any passwords or other personal data in order to complete the test, memorize, print, or write them down before you begin.
Test while logged in as Guest. Same problem?
After testing, log out of the guest account and, in your own account, disable it if you wish. Any files you created in the guest account will be deleted automatically when you log out of it.

Overnight my MacBook Pro (2012) has become very slow when trying to complete any task. I have plenty of space left and have emptied my trash but the problem persists. For added detail, I did just get an iphone which may be slowing my computer down through Icloud? Also, I did try downloading a file from a program called vuze, but I have done that before with no issues. Otherwise, I havent changed or done anything out of the ordinary to bring about this issue. If you have any suggestions that would be great, thanks.

This procedure is a diagnostic test. It changes nothing, for better or worse, and therefore will not, in itself, solve your problem.
If you don't already have a current backup, back up all data before doing anything else. The backup is necessary on general principle, not because of anything in the test procedure. There are ways to back up a computer that isn't fully functional. Ask if you need guidance.
Below are instructions to run a UNIX shell script, a type of program. All it does is to gather information about the state of your computer. That information goes nowhere unless you choose to share it on this page. However, you should be cautious about running any kind of program (not just a shell script) at the request of a stranger on a public message board. If you have doubts, search this site for other discussions in which this procedure has been followed without any report of ill effects. If you can't satisfy yourself that the instructions are safe, don't follow them.
Here's a summary of what you need to do: Copy a line of text from this web page into the window of another application. Wait about a minute. Then paste some other text, which will have been copied automatically, back into a reply on this page. The sequence is: copy, paste, wait, paste again. Details follow.
You may have started the computer in "safe" mode. Preferably, these steps should be taken in “normal” mode. If the system is now in safe mode and works well enough in normal mode to run the test, restart as usual. If you can only test in safe mode, do that.
If you have more than one user, and the one affected by the problem is not an administrator, then please run the test twice: once while logged in as the affected user, and once as an administrator. The results may be different. The user that is created automatically on a new computer when you start it for the first time is an administrator. If you can't log in as an administrator, test as the affected user. Most personal Macs have only one user, and in that case this paragraph doesn’t apply.
The script is a single long line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, though you may not see all of it in your browser, and you can then copy it. If you try to select the line by dragging across the part you can see, you won't get all of it.
Triple-click anywhere in the line of text below on this page to select it:

Copy the selected text to the Clipboard by pressing the key combination command-C.
Launch the built-in Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
When you launch Terminal, a text window will open with a line already in it, ending either in a dollar sign ($) or a percent sign (%). If you get the percent sign, enter “exec sh” and press return. You should then get a new line ending in a dollar sign.
Click anywhere in the Terminal window and paste (command-V). The text you pasted should vanish immediately. If it doesn't, press the return key.
If you're logged in as an administrator, you'll be prompted for your login password. Nothing will be displayed when you type it. You will not see the usual dots in place of typed characters. Make sure caps lock is off. Type carefully and then press return. You may get a one-time warning to be careful. If you make three failed attempts to enter the password, the test will run anyway, but it will produce less information. In most cases, the difference is not important.
If you're not logged in as an administrator, you won't be prompted for your password. The test will still run. It just won't do anything that requires administrator rights.
The test may take up to a few minutes to run, depending on how many files you have and the speed of the computer. A computer that's abnormally slow may take longer to run the test. There wiil be nothing in the Terminal window and no indication of progress until it's done. Wait for the line "[Process completed]" to appear. If you don't see it within half an hour or so, the test probably won't complete in a reasonable time. In that case, close the Terminal window and report your results. No harm will be done.
When the test is complete, quit Terminal. The results will have been copied to the Clipboard automatically. They are not shown in the Terminal window. Please don't copy anything from there. All you have to do is start a reply to this comment and then paste by pressing command-V again.
If any private information, such as your name or email address, appears in the results, anonymize it before posting. Usually that won't be necessary.
When you post the results, you might see the message, "You have included content in your post that is not permitted." That's because the forum software falsely identifies something in the post as a violation of the terms of use. If that happens, please post the results on Pastebin, then post a link here to the page you created.
Note: This is a public forum, and others may give you advice based on the results of the test. They speak only for themselves, and I don't necessarily agree with them.

Firefox has become extremely slow in the recent times

Firefox suddenly has become very slow. It takes too much time to load all websites and even the typed words and scrolling has a great delay in appearing. It becomes unresponsive very often. I tried reinstalling it and even reset it. Its becoming a pain to use this to surf the net. Please do help!!

I also have found that Firefox has become a dog. I've followed one thread that disabled the plugin-container with no help. 20.0.1 can hang for over a minute and actually hog my entire CPU so I can't even start Chrome! I like my FF plug-ins, but the performance problems of FF 20 are becoming intolerable and no one seems to know what the heck! Chrome does not present the problems and I have been visiting and working at the same websites. If many folks are encountering this mess, I suspect that FF is done for. I have actually found that the Android FF is also tending to slow down my smartphone - stall it! I am a few days away from just removing FF from my computing life.

HT4623 After updating my Ipad now has No Sim message...

Hi.. After updating my iPad to the latest software.. I am getting 'No Sim' message... I've tried rebooting the iPad but no luck.. I've removed and reinstalled the sim?

Hey Juanita16may,
Thanks for the question. I understand that you are experiencing issues with your iPad 2 and your SIM card. The following resource may provide a solution. Keep in mind that some of the steps may be iPhone-specific, but most should be applicable for your iPad:
iPhone: Troubleshooting No SIM
http://support.apple.com/kb/TS4148
1. Update your iPhone to the latest version of iOS.
2. Toggle Airplane mode On and Off.
3. Try turning iPhone off and then on again.
4. Check for a carrier settings update. Tap Settings > General > About. If an update is available, a prompt will appear.
5. Remove the SIM Card and verify that it is a valid, carrier-manufactured SIM. Also verify that it is not damaged, worn, or modified. Then reinsert it.
6. Restore the iPhone.
If you still are unable to resolve this issue, contact Apple support for further assistance.
If your issue persists after completing all of the steps, please follow the last section to contact Apple support.
Thanks,
Matt M.
