Recently, since upgrading to ver. 8.0.1, videos are extremely choppy, scrolling is choppy and loading pages is slug slow. I have a very fast quad core i7 processor and plenty of RAM & HD space.
Sometimes a video will start smooth but within moments it becomes very choppy and jumps from image to image. The browser itself does the same thing where it bogs down to a crawl and scrolling is also very choppy. Very frustrating. I have been using Firefox for years now since it first hit the scene, but until I upgraded to ver. 8 this did not happen.
Please see the help article on what to do when <ins>[[Firefox is slow]]</ins>
and the help article on <ins>[[High memory usage]]</ins>
See also the help article on <ins>[[Managing the Flash plugin]]</ins> which describes how to adjust hardware acceleration.

I had no issues with Ver 9.01 but since upgrading to Ver 12 it takes forever to startup but is unusable when it finally comes up. Any ideas why and how do I fix it. IE 9 and Chrome have no issues.
Try to start Firefox in [[Safe mode|Safe mode]]. This mode disables all extensions, user customizations, hardware acceleration, etc. temporarily for diagnostic and troubleshooting. If Firefox works fine in Safe Mode, then this is likely an add-on issue. Restart Firefox in normal mode, then type "About:addons" (without the quotes) in the address bar. Disable your extensions one by one, restarting Firefox between each one, until you find the trouble maker. Once you do, you can disable that add-on and report the issue to that add-on's developer.
A few other basic trouble shooting things you can try is this:
Run all Windows Updates, install all needed service packs, etc.
Update your graphics driver (Firefox uses your graphics card for some rendering, and an out of date graphics card driver can cause problems. [https://support.mozilla.org/en-US/kb/how-do-i-upgrade-my-graphics-drivers https://support.mozilla.org/en-US/kb/how-do-i-upgrade-my-graphics-drivers].
Update all your plugins (Flash, Java, etc.): [http://www.mozilla.org/plugincheck/ http://www.mozilla.org/plugincheck/].
Download and Install MalwareBytes Anti-Malware, run a full Scan. [http://www.malwarebytes.org/ http://www.malwarebytes.org/]. This helps check that there are no viruses on your computer causing issues. You can uninstall this program after you clean off any infections. -
Since upgrading to ver 3.6.13 FF not closing!
Hi Folks,
Since upgrading to ver. 3.6.13 FF won't close unless I do so through Task Manager|Processes.
I haven't installed any new Add-ons, Themes or Extensions. Just allowed Add-ons and/or Extensions to upgrade.
BTW, I've been using FF for several now and have upgraded every time the new versions have come out (and '''ONLY'''' from the FF site!!).
Any ideas???
Many thanks in advance..* "Clear the Cache": Tools > Options > Advanced > Network > Offline Storage (Cache): "Clear Now"
* "Remove the Cookies" from sites that cause problems: Tools > Options > Privacy > Cookies: "Show Cookies"
Start Firefox in [[Safe Mode]] to check if one of the add-ons is causing the problem (switch to the DEFAULT theme: Tools > Add-ons > Themes).
* Don't make any changes on the Safe mode start window.
See:
* [[Troubleshooting extensions and themes]] -
Ever since upgrading to Mountain Lion, my AOL messages sometimes, but not always open with a blank page. If I open AOL in Firefox, the messages open fine. This does not happen with any messages by any means, and it is not any type of certain message. In fact, in the same screen I can often open an email from the same sender with email intact. This is weird. Sometimes I close the page and open a new page. Sometimes that works and sometimes it does not. It is a very annoying thing.
Hi,
When you start Messages fro the first time you are asked for an Apple ID
When this is verified and entered it appears in Messages Menu > Preference > Accounts and is Enabled.
The App should have also picked on on those iChat Accounst you had before.
These should be Enabled if they were when you last used iChat.
Exactly which "Accounts" are logged in can be seen in Message Menu > Accounts and will include the iMessage "Account" and Bonjour.
In the Window menu you will see CMD +0 for the Messages window and CMD+1 for the "Buddies" window which is a combined list at this stage.
Go to the Preferences > General Section and Untick the "Collect all accounts into one list".
This will give you separate iChat type Buddy lists.
You can check if that account/Buddy list is set to Invisible or if in the Preferences > Accounts > Security you have settings that will block some people from seeing you as On line.
You are saying Buddies can see you as On Line which implies they are still sending to your AIM based Names (@Mac.com is a valid AIM Screen Name)
I am not sure from your post if you are trying to iMessage their email IDs thinking they are Apple IDs and that they are using Messages as well.
There is no Buddy list for iMessages side
No-one can tell you are "On Line" until they have your details in the "To" spot in Messages with the correct iMessaged contact info (iPhone Number or Apple ID)
Obviously an Apple ID can be an email or look like one.
In some cases they are also valid AIM Screen Names as well.
In the case or the @mac.com name you may have linked this Apple ID to iMessages as well.

Core i7 processor, and considerations of RAM upgrade configurations
According to Intel, the Core i7 can access:
3 Channels of DDR3 1066 MHz memory...
and if this is true for Apple's new iMac 27 Quad cores, wouldn't it be most efficient to install RAM in sets of three (ie 3x4GB) = 12GB total; not sets of two (2x2MB + 2x4GB) = 12GB? And why doesn't the Apple Store offer those combinations of RAM configuration?
This affect my considerations for future purchase. If not then:
If and when Mac Pro go to Core i7, will this configuration of RAM (3x4GB) be applicable?There are many models of Core i7. The Core i7-860 used in the iMac (late 2009) only uses dual channel memory access. So you will get the best access speeds if you install memory in match pairs such as 2x2GB and 4x2GB or 6x2GB or 2x4GB or 4x4GB. You can mix and match such as 2x2GB plus 2x4GB sticks. These will all be matched pairs and run at full speed.
Now a new innovation of the i5 and i7 processors with built-in memory management is that they can handle memory this is not in a matched pair without degrading the memory performance of memory that is in a matched pair. For example 2x2GB plus 1x4GB. In this example, the 2GB sticks will be accessed via dual channel and run at maximum speed; the single 4GB stick will only use single channel access and will hence run slower but it will still work.
The Mac Pro architecture uses triple channel access when memory is installed in threes. For example 6x2GB or 6x4GB. The system also supports 8x2GB and 8x4GB but in those configurations, with the current Xeon processor and chipset, the memory will all be accessed then in dual channel mode. If your system is begging for more memory, running with dual channel will possibly be faster than running triple channel on a smaller amount of memory. If you are not severely memory constrained, then running the triple channel configurations will be faster. -
I recently bought two iMac quad core i5 processor speed 2.5 Ghz. Every time I use Air Drop and I send a file from one iMac to the other, a black curtain drops and I am asked to restart the computer!!! What can I do?
That's a kernel panic and indicates some sort of problem either with the computer's hardware or software. Visit The XLab FAQs and read the FAQ on diagnosing kernel panics. It would help to post the panic log: Mac OS X- How to log a kernel panic.
Meanwhile, try booting the computers into Safe Mode then restarting normally. If this is simply a disk repair or cache file problem then this may fix it.
You can also try creating a new admin account on each computer then booting into the new account. This would help determine if the problem is related to a bad file in the user accounts. -
I'm running a 27" imac with a 3.4ghz core i7 processor and 16 gb of ram.... In logic I have a project with 7 audio tracks with various plugins running and 4 software instruments which incidentally are not playing all the way through the track...my CPU spikes even if the project is paused...why is this happening on such a high end machine.....wasting my money again seems to spring to mind !!

Can I Upgrade my computer to Lion. I have a 2 GHz Intel Core Duo Processor. My computer is 6 years old. Right now I have Snow Leopard.
I have an old iMac about that age that I upgraded to Lion to test my 3rd party applications for compatibility. It upgraded quite simply. Please backup or save all your info/etc to an external CD/DVD/Hard drive, then try to run the installer. The Lion installer will analize your Mac for compatibility before it does anything, and will alert you to it's decisision. My 17" iMac is also 2 GHZ Intel core duo. Surprisingly for many of the things I use it for it works as good as my multi thousand dollar MacPro workstation. Best of luck. But Lion isn't compatible with many third party applications and drivers for printers; scanners; etc.

If I do an end task on plugin_container using Windows task manager, the typing response problem seems to go away temporarily. However, the plugin_container process soon restarts itself and the typing issue returns. It has happened four or five times while typing this note. Sometimes I start typing and the display of characters typed does not appear or while typing an displaying what is typed normally all of a sudden stops being displayed and eventually is displayed all in a blast of characters.
When I try to print a web page, the header and footer info that I have selected show in the print preview but disappears when I print the page and does not print on the hard copy.
I believe that both of the above situations began when I upgraded to Firefox version 8.
I tried to search for problems like the above with Firefox but could find nothing.
I tried all of the above in IE and IE works as it has in the past.
Is this a Firefox issue with version 8 or is there something wrong with my PC all of a sudden?Response to cor-el suggestions:
I tried what you suggested as far as checking the theme (it's "Default 8.0") and deleting the sessionstore files (there was one .js file, one -1.js file and one .bak file). I still have the same slow response problems (especially typing, it has gone dead on me for a short time twice while typing this replay so far, now a third time) and lost of headers and trailers and some data.
I did the suggested actions three times just to make sure that I was doing them correctly. On the first try, the sessionstore.js and sessionstore-1.js was more than twice the size of sessionstore.bak. Since doing what was suggested, the sessionstore.js and sessionstore.bak are, I believe, the same size. I did not write down their size is why I am not certain.
The printing problem appears to only be with one website which is an investment website which I would prefer not to document here. I print from this website each weekday and I have confirmed that the printing problem started when the upgrade to version 8.0 occurred.
I need a solution to this or I am going to either go back to IE (Ugh!) or find another browser. The typing delays are an extreme annoyance since I do lots on the Internet including a lot of emailing. The delays also involve the buttons to select functions within a website.
Is there a way to get back to the version previous to version 8.0? -
Since upgrading to ver 11 flash player 11 disapears on reboot
Since upgrading to firefox 11 I have to reinstall adobe flash player 11 each time as it disappears when I reboot. But works fine otherwise.
Also after downloading the download window stops responding. This is happening all the time lately.Ok, let's try a few steps here:
Please use the Flash Play Uninstaller located here: [http://helpx.adobe.com/flash-player/kb/uninstall-flash-player-windows.html http://helpx.adobe.com/flash-player/kb/uninstall-flash-player-windows.html] (if you have a 64 bit system, run both the 32 bit and the 64 bit versions).
Then, restart your computer. Download this file: [http://fpdownload.macromedia.com/pub/flashplayer/current/licensing/win/install_flash_player_11_plugin_32bit.exe http://fpdownload.macromedia.com/pub/flashplayer/current/licensing/win/install_flash_player_11_plugin_32bit.exe], run it (with all browsers and other windows closed).
Then, restart your PC one more time. Try opening up Firefox, does flash work properly now? -
I am using Windows XP, SP3. I have experienced this printing problem with anything I print from the internet, any site. I can read whatever I am printing, but there is a light gray background on the whole page. I saw something similar in the problems already listed in the help section, but the fix in the about:config files did not help; same problem existed. The only thing that fixed it was to uninstall Firefox 4, and reinstall the prior version. I am now using version 3.6.17. I have read the warning when I start Firefox to seriously consider upgrading to version 4, and that the older version won't be supported, but since I can't print from it without wasting considerable ink, and having pages that are unattractive and difficult to use, I don't know what to do. Please help. I want to use the new version, but MUST be able to print clean pages, without a gray background on each one.
I have had a similar problem with my system. I just recently (within a week of this post) built a brand new desktop. I installed Windows 7 64-bit Home and had a clean install, no problems. Using IE downloaded an anti-virus program, and then, because it was the latest version, downloaded and installed Firefox 4.0. As I began to search the internet for other programs to install after about maybe 10-15 minutes my computer crashes. Blank screen (yet monitor was still receiving a signal from computer) and completely frozen (couldn't even change the caps and num lock on keyboard). I thought I perhaps forgot to reboot after an update so I did a manual reboot and it started up fine.
When ever I got on the internet (still using firefox) it would crash after anywhere between 5-15 minutes. Since I've had good experience with FF in the past I thought it must be either the drivers or a hardware problem. So in-between crashes I updated all the drivers. Still had the same problem. Took the computer to a friend who knows more about computers than I do, made sure all the drivers were updated, same problem. We thought that it might be a hardware problem (bad video card, chipset, overheating issues, etc.), but after my friend played around with my computer for a day he found that when he didn't start FF at all it worked fine, even after watching a movie, or going through a playlist on Youtube.
At the time of this posting I'm going to try to uninstall FF 4.0 and download and install FF 3.6.16 which is currently on my laptop and works like a dream. Hopefully that will do the trick, because I love using FF and would hate to have to switch to another browser. Hopefully Mozilla will work out the kinks with FF 4 so I can continue to use it.
I apologize for the lengthy post. Any feedback would be appreciated, but is not necessary. I will try and post back after I try FF 3.16.6. -
Has anyone else had this problem since upgrading their iPhone and iPad to iOS 7?
See Pierre-Yves 1 post: https://discussions.apple.com/message/23297197#23297197
This was driving me crazy. Sync between Outlook 2007 and my iphone was working perfectly on ios 6 - I primarily sync Calendar, contacts, and notes.
Then everything went bizerk with ios 7... All of a sudden nothing was getting syncronized, but rather multiple Calendars and Contacts showed up in Outlook 2007. Disabling Calendar, contacts, and Notes in my iphone's icloud settings did the trick. Now I have ONE Calendar and ONE contact list in Outlook, fully in sync with my iphone.
