Starts at start without any problem or disk permissions, i did the search for errors in the system for the disk utility application and did not get any, usually 5 times I turn on the computer one is safe boot time, which is still not the problem, thanks for your help.
Enciende en modo arranque seguro sin ningún problema o errores en el disco ni en los permisos, hice la búsqueda en la aplicación de utilidad de discos pero no apareció nada, normalmente de 5 veces que enciendo la computadora 1 vez es en arranque seguro, aun no se cual es el problema, gracias por su ayuda

Hello,
Do you mean it fails to start up completely?
Bootup holding CMD+r, or the Option/alt key to boot from the Restore partition & use Disk Utility from there to Repair the Disk, then Repair Permissions.
If that doesn't help Reinstall the OS.

My Firefox won't quit and gives a "not responding" message after I use Google Mail. I have tried starting in "safe" mode and the problem still occurs.

I have an issue where Firefox wont' quit and gives a "not responding" message after I have been using Google Mail. It works fine when I am not using that program. I have tried Safe Mode and the problem still happens when I go to Google Mail, so it is not connected with add-ons, extensions, etc.

Many site issues can be caused by corrupt cookies or cache. 
Clear the Cache 
'''''Firefox/Tools > Options > Advanced > Network > Cached Web Content: "Clear Now"'''''

Poke around safe web sites and see if there is still a problem. Then restart.

MacBook pro will not boot. I get the gray screen, an apple icon and spinning wheel. Tried to start in safe mode but get the same screen. The only thing different was that I loaded the zedge sync app yesterday. Now getting this problem.

Macbook pro will not boot. I get the gray screen, an apple icon and spinning wheel. I tried to start in safe mode, but get this same screen. The only thing different is that I added the zedge update app to do a sync for adding ringtones to my apple cell phone. How can I get a good boot. I am fairly new to apple computer.

Reset PRAM: http://support.apple.com/kb/PH4405 and then try a normal boot.
Run the Startup Manager to select Startup disk: http://support.apple.com/kb/HT1310
If those did not work your disk may be sick or dying. The top priority at this point is to make a backup copy of your data.
Check the health of the disk. Boot in Recovery Mode (Boot, Command-R). Run Disk Utility. Click on the upper left disk icon. Does the S.M.A.R.T. status say “Verified”? If not the disk/SSD is unhealthy and needs to be replaced. Even if it does not show “Verified” you can still attempt a backup.
Click on the icon indented below, usually called “Macintosh HD” and Verify Disk. If it finishes with a green “OK” message then all is well with the disk. If it shows errors in red then you have found a problem to address once the system is backed up. Do not attempt software repairs until you have secured the data.
If the disk will not show up at all in Disk Utility as your ran the tests above then it may be dead or it may have a bad internal SATA cable. A trip to an Apple store for confirmation would be in order.
If you have an external disk drive you can use as a backup drive then do so. If not Google “Hitachi USB 3.0 external hard drive 1TB” to purchase one or go to a brick-and-mortar store (including an Apple store) to pickup one. Any 1 TB external drive will do.
Assuming it is still breathing you can try to recover the data without booting from the sick disk.
Reformat the external disk. (This will erase all data on the external disk.)
Boot in Recovery Mode. Start Disk Utility. Plug in the new disk. Select it’s disk Icon (the second one down, left justified). Select the Partition tab.
Partition Layout > Single Partition
Name: Emergency Recovery 1 (or whatever name you wish to use)
Format: Mac OS Extended (journaled)
Options… > GUID Partition Table > OK
Apply
Select the Restore tab.
Drag the old system volume (Macintosh HD) to Source.
Drag the new disk volume (Emergency Recovery 1) to Destination.
Click on Restore.
It may take a long time for the backup.
If that will not complete post back for other emergency data recovery methods, including those from a brody.
If the backup succeeds, use the First Aid tab in Disk Utility to select the old volume (Macintosh HD) and Repair Disk. If it does not finish with a green OK message try to repair it once or twice more. If it repairs with a green OK message, will it boot normally? If not, boot from the Recovery Partition and reinstall OS X.
If it is still not healthy, post back for further instructions.

Starting in safe mode did not solve the problem

The problem of web sites failing to open by using links in e mail for LA Times and Coldwater Creek was not resolved by starting in safe mode.

Is this with clicking a link in an external program?
Try to redo the default browser (temporarily make another browser the default browser).

Upgraded to 6.0.2, now get "Firefox had a problem and crashed". Starting in Safe Mode does not help. Now what?

Not sure what version I was running, but it worked fine but I have not been able to get it running again. I have uninstalled and reinstalled with the same results. Have followed the help pages to the point of obtaining the Crash Report... now what?
I did notice the CR seems to think I am running Windows XP but I am actually running Windows 7 (64 bit).

That gives Firefox 6.0.2 Crash Report [@ nsHttpHandler::QueryInterface(nsID const&, void**) ] https://crash-stats.mozilla.com/report/index/d2eddeb0-5845-4c72-987a-ad0282110917
Unfortunately that is not really getting anywhere yet, you could become the first person to file a bug about that particular crash, but that takes a bit of time and testing.
There is a known problem causing firefox 6 to crash and that is the use of IDvault, that can give more than one crash signature, the software developers regarding ID vault are WhiteSky, and are expecting to release a fix in a few days (if they have not already done so)
Have you tried
* using firefox's [[safe mode]]
* disabling all plugins
Does that help, either by preventing crashes or giving another recognised crash signature. You should also ensure all software is up to date, before trying adding extension software back.
The other common cause of crashes is malware, that includes a particular Trojan that is now known to crash Firefox 6. Check out [[is my firefox problem a result of malware]] you will need to do scans using software or sites with up-to-date scanning software, if you do scan for problems say what sites or software you used and the version of software used. Downgrading firefox versions rarely helps with crashes, it may help with the one specific trojan, but the security risks would then remain, potentially causing even more problems because the browser no longer crashes.

Problems after Starting in Safe Mode

I booted my computer up in safe mode in order to resolve a separate software issue. When I restarted my computer, I got to the blue screen with the apple logo and the spinning progress icon, and it just stays there for about a minute and shuts down again. Now I can't get past this screen no matter what I do. I tried holding down shift for safe mode again with no luck.
Any suggestions would be greatly appreciated.

Try resetting PRAM:
Restart Mac while holding down "option/alt", "command", "P", "R" (all 4). Keep all 4 keys depressed until the audio signal is heard 2 times (some say 3). Hopefully, this may solve your problem.

Firefox immediately crashes on opening, will start in safe mode, problem just began a few days ago

First crashed under Firefox 9, then installed 14, still crashes. Will not allow me to update add ons.
Uninstalled Firefox, downloaded 14 and reinstall, still crashes. Attaching last crash report.
Problem started one day ago.
If I shut down my computer and restart and then run Firefox first it will run, but once it is closed or another program run, it crashes.

See if this helps you. https://support.mozilla.org/en-US/questions/934283

Some sites (nytimes) take forever to load - seems to relate to graphics or CSS files. Problem occurs in safe mode. No problems on same sites using Chrome.

By forever, I mean that the loading icon spins and spins. Often, but not always, if I stop the load and reload, the page loads instantly.

Hello sjkappel,
Many site issues can be caused by corrupt cookies or cache. In order to try to fix these problems, the first step is to clear both cookies and the cache.
Note: ''This will temporarily log you out of all sites you're logged in to.''
To clear cache and cookies do the following:
#Go to Firefox > History > Clear recent history or (if no Firefox button is shown) go to Tools > Clear recent history.
#Under "Time range to clear", select "Everything".
#Now, click the arrow next to Details to toggle the Details list active.
#From the details list, check ''Cache'' and ''Cookies'' and uncheck everything else.
#Now click the ''Clear now'' button.
Further information can be found in the [[Clear your cache, history and other personal information in Firefox]] article.
Did this fix your problems? Please report back to us!
Thank you.

HP Stream 7 with Windows 8.1 - "Start Menu (Metro)" mode - closing apps problems

Ok, this is probably more of a Windows 8.1 issue, but I've noticed two things about closing apps (swipe down from top of screen):
1. If the app is "wider" than the display, and you scroll to the right, you CANNOT close the app unless you scroll all the way back left.
2. Any app that has any controls anywhere near any area of the top of the screen is extremely difficult to get it to start closing. I have tried as many as 10-15 times for some apps to close them. And anytime you get near those "controls" at the top - you can see you are affecting them as you slide your finger down - NOT the app.
3. When I have a BT mouse connected, I've noticed that putting the mouse towards the top of the screen will "pop" up something akin to the old Windows title bar, with a close button in the upper right (and a brief menu in the upper left). This works great - but doesn't seem to work with a finger or stylus - only the mouse. Is there a setting to change that to make it easier to close apps?
Suggestions?

Oh - might add, I'm taking it down to 802.11 b/g, instead of b/g/n, based on the other post.
I'm going to say there's something wrong with the "n" side, especially since it seems (after some reading), that it's really only "n" on the 2.4Ghz side. Most devices these days are "expected" to be on the 5Ghz to support the faster speeds. So I'm going to say that I suspect there's something at odds there in that type of config attempting to use "n" with this device.

HT1338 I updated my MacBook Pro with Mountain Lion and now it is starting slow and opening with some of the programs. How can I fix the problem?

I updated my MacBook Pro with Mountain Lion and now it is slow in starting up and loads a number of probrams. How can I fix the problem?

Have you tried starting in Safe Mode and see if the slowness still occurs?
Restart holding the "shift" key.
(Expect it to take longer to start this way because it runs a directory check first.)
If this works look in System Preferences > Users & Groups > Login items and delete any third party login items (-), you can always add them back with the (+). Also look in /Library/Startup Items. Nothing is put in that folder by default, so anything in there is yours.
Reboot normally and test.

I have 3 toolbar folders in my bookmarks library, can I delete the two I don't use without causing problems?

I recognize the two "unwanted" folders but have no idea how they got in the library. In the past year I have had two major computer crashes. The last one required a complete reformatting of my formerly partitioned hard drive. I think the file restores from my offsite back-up service somehow created the duplicate folders.

What is the title of the other bookmark folder that can not be deleted?

[VIA] I have some problems with the KT6V motherboard...

This is what i have right now for that motherboard: i have an AMD Athlon XP 2800+, All-in-Wonder ATI Video Card, and recently bought a PC3200 512MB DDR ram for it
Well I installed everything that should be connected to the motherboard, when I turn it on, it comes up with this:
Scan Devices, Please wait...
Press<Tab> Key into User Window!
Serial_Ch0 Master:No Device
Serial_Ch1 Master:No Device.
then it does the load whats indicated in the BIOS, which is the hard drives I have in it. and does that, gets up to a part where it says the computer has been shut down improper and asks if you want to start in safe mode and such, so i hit enter on Start windows normally, and after that, it restarts it does that everytime and i have no clue how to fix it.
If you know how to fix it, that would be awesome.

I agree with STU.Use the WINXP CD to format.I usually go into BIOS and make CD rom first boot device.Put in WINXP CD and boot from the CD.Whan prompted to install WINDOWS,DELETE the partition that it already has and do a fresh format called "RAW".That way you ensure that every file was wiped off the drive.
Almost forgot.Leave it all underclocked.After installing WINXP,load the VIA 4 IN 1 drivers first.Do all you windows updates(I would not install SP2 though)Then you can procede to clock the board to the correct settings.From my experience,if you try to run FSB and RAM and correct speeds before loading WINXP it can and has caused the system to hang before finishing loading and also BSOD if you have to try to resume from where it hangs and continue the install.Not sure why this happens but it worked for me "EVERY" time on several machines with no problems.

When i double-click the mozilla icon, it doesn't start. In the task manager i noted that the process "firefox.exe" appears and desappear after 5 seconds. The problem remains in mozilla safe-mode, but not in windows safe-mode. Thks!

Yesterday i installed the firefox 6.0 on my windows 7 computer. When i double-click the mozilla icon, it doesn't start. I opened the task manager and noted that the process "firefox.exe" appears and desappear after 5 seconds. I tried to start mozilla in safe mode but the problem remains. The only way to use mozilla in my computer is restarting the windows in safe-mode. Last thing: i already tried to reinstall the program. Please help me!

I'm also using Windows 7 on a Lenovo U310 laptop.
