Firefox 8.0.1 will not open. IE will not open as long as Task Manager shows firefox process is running.

Running Vista Ultimate. Yesterday Firefox stopped opening. only change to system was a new video driver for Intel 965 mobile express chipset. AOL 9.6 and IE 8 also stopped opening. When I killed the 2 firefox processes from Task Manager IE 8 opened. But AOL 9.6 is stuck at "updating locations". I tried the troubleshooting page but since most require the application to be open I was not able to try anything except restarting the computer and reinstalling after deleting the Mozilla Firefox folder.

Did you try the solution given in this article?
[[Flash 11.3 doesn't load video in Firefox]] (applies to Flash 11.3 and above) 
'''Solution 1: If you have RealPlayer installed - update it'''
If that doesn't resolve the problem, maybe something here will help (and let us know what you've tried already)

Firefox does not appear on screen when started from the start menu, but task manager says the process is running

Firefox does not appear on screen when started from the start menu or the shortcuts, but task manager says the process is running.

No - I get the message basically saying "Can't run program while Firefox is running. Please close down Firefox & try again".
I rebooted my computer and it all works now - but that's weird it was happening before. Kinda weirded out that it happened at all.
To avoid that happening again, I still wanna know what to do to avoid it or fix it for next time. Thanks

Frequently when I open Firefox it says Firefox is already running but is not responding. I have to go to the task manager, find Firefox and close the process before I can get firefox to load.

Those are all the details I have

There is an article about this problem see:
* [[Firefox is already running but is not responding]]

Firefox does not start in Windows Vista. It can be seen in the task manager that the process is running. But nothing happens. After deleting the process it still does not work.

Are there any issues with Firefox 10 and Vista? IE works.

Hi webero,
There are no Known Issues that I am aware of. You should take a look at [[Firefox is already running but is not responding]] and our article called [https://support.mozilla.org/en-US/kb/Firefox-not-start Firefox will not start].
Hopefully this helps!

Windows 7 Task Manager shows "Firefox 32" - Is there a 64 bit version?

I don't see an option on the Mozilla download page for a 64 bit version. Is there one, or is Firefox only available in a 32 bit version? Thanks...

Not really at the moment. (Assuming you are talking Windows)
Work on this speeded up recently and it may be available a bit later in the year.

I've had issues with Firefox hanging in memory even if I try to remove it using the Windows task manager's "End Process" button. My only alternative is to force a reboot on my PC.

Since upgrading to Firefox 7.0.1 I've noticed the abovementioned problem. I usually have a couple of app tabs with GMail information on them (two different e-mail accounts, one of which is just the contacts page and the other is the inbox and one tab with a GMail calendar for one of the accounts) and my home page, which is Google News. While I cannot say for certain that it is related to multimedia streaming, it does appear to happen after I play some kind of video file like the videos for The Daily Show with Jon Stewart. My O/S is XP Pro SP3, my PC is a Dell Inspiron 700m w/2GB RAM. The Add-Ons that I have, as far as I can remember, are AdBlock Plus, Tab Mix Plus, WOT Safe Browsing Tool, and Download Statusbar along with the usual Java stuff. My Adobe plug-ins are always updated whenever I get an update message.

Firefox begins to start but then stops before loading any screen. Profile manager/safe mode appear then disappear. Task manager shows programs briefly in CPU then they disappear. Uninstall & reload makes no difference. Any ideas please ?

When we clicked as usual on the firefox icon the egg-timer started then went off. Nothing started up.
Checking the Task Manager showed firefox.exe briefly using the CPU then it dropped off the list.
We tried to uninstall and reload from the mozilla site (http://www.mozilla-europe.org/en/firefox/). Installation seemed to work ok, but the same problem recurred when we tried to start firefox.
Did this again, this time removing bookmarks, etc. same result.
Tried to use the profile manager - the screen came up but disappeared before we could use it.
Same thing happened when we tried to start in safe mode - screen briefly appeared but then disappeared.
Tried googling in IE to solve the problem but nothing seems to apply.
Have run all security checks but no apparent bugs or problems.
Have had to abandon firefox and use another browser. How do we get it back please ?

Did you check your security software (firewall)?
A possible cause is security software (firewall) that blocks or restricts Firefox without informing you about that, possibly after detecting changes (update) to the Firefox program.
Remove all rules for Firefox from the permissions list in the firewall and let your firewall ask again for permission to get full unrestricted access to internet for Firefox.

For some inexplicable reason, Safari 5.1 will not open in Windows 7. It appears in task manager briefly and then disappears. No windows open; I have tried everything. Any ideas??

I fixed the issue. It was related to the DEP settings on my windows machine.

Firefox does not close/exit and must be shut down using task manager

When I "x" out of Firefox, or File menu "exit" or right click to "close," the Firefox window closes but whenever I attempt to restart Firefox, it says that it is already running (hence was never shut down) and I have to use Task Manager to "end process" before re-starting Firefox again. This dilemma only started after upgrading about 6 months ago (can't remember the version). I recently upgraded again but the problem still exists.

Did not address my issue. Firefox isn't freezing while it's up and running, it just doesn't completely shut down... therefore it's always running behind the scenes.

Firefox Can not be completely shut down, Have to use Windows Task Manager to shut it down, I am using Vista, How to fix it????

Firefox doesn't load webpages at random times, after closing and terminating it in task manager it works again

I just did a fresh install on my computer, and whenever I open firefox and leave it there for a while it would stop loading any web pages. When I close it and reopen FF it tells me that FF is still running and I have to use task manager to end process to reopen FF and it'd for for a while and repeat itself.
Thanks for any help in advance.

Hi Andis.
First of all, this is completely normal behavior, although it's a bit irritating, I know. What happens is that when you close Firefox, despite the window disappearing right there and then, Firefox keeps running for a little bit until the whole closing procedure is completed. This can take a fraction of a second on fast computers, or can take a few seconds on slow computers or when Firefox is storing a large session (if you save your tabs). All you have to do is wait a bit until Firefox closes, and then open it again.
To see if it's still running, you can press CTRL+SHIFT+ESC and then, under the Processes tab, you can see if firefox.exe is still there. If it's taking an unusual amount of time to close (which happens very rarely, and only if the browser freezes on exit), you can force the application to terminate from this application (task manager).
Firefox 4.0 will reduce by 97% the time it takes firefox.exe to close, so this problem will be basically erased for Firefox's next version.
Until then, I can recommend you this extension, which helps you restart your browser more easily and without bothering about closing times:
https://addons.mozilla.org/en-US/firefox/addon/3559/
Hopefully this will help.

Firefox won't stop running unless I go into task manager and end process

when I shut down firefox and then later try to start it again a box comes up that says it is already running but it won't come on. So I have to go into my task manager and end the process before I can start it again. How do I solve this problem?

That is "hanging at exit". You can ignore the first part, since you already know how to do that.

Reader x or xi does not load; task manager shows 750 kb memory used

I am using windows 7 home premium 64 bits, and adobe reader x or xi sometimes does not load. However, the task manager shows that AcroRd32.exe is loaded, but only using aroung 750 kb of memory.
I must restart windows, or at least close sesion and sometimes reader loads properly. Sometimes the computer must be restarted twide to adobe function.
Does anybody has an idea why this is happening?

I'm experiencing the exact same issue.
I am on Windows 7 Professional x64 SP1. I have updated Adobe Reader to latest version, and do not have other older versions of Reader installed. I have tried opening reader by itself using Run As Administrator, as well as Run as Another User, and also in XP SP3 compatibility mode. I have tried to force PDF files to be opened in a browser window by right clicking them, selecting Open With and then selecting Internet Explorer. Nothing works. I have had this issue before, and SOMETIMES it will help if I uninstall Adobe Reader and reinstall, but even after re-imaging my entire PC, this issue comes back.
As with original poster, all I get when trying to open PDF files is AcroRd32.exe showing in Task Manager and using between 700k and 1785K of memory. No matter how long I wait, nothing else happens.
This is getting very frustrating.
Seeing as I cannot load Adobe Reader at all, is there a way to disable protected mode without loading Adobe Reader (like with registry setting)?

My Firefox continues to stall a lot and Window Task Manager shows that Firefox is using a lot of memory (600,000k +) What can I do to make this stop stalling?

I play Farmville or on Pogo and my computer keeps giving me the hour glass and when I look on my Windows Task Manager it shows that I am using over 600,000 k of memory. When it does that I can't do anything unless I just use the power button to shut the computer down or use the task manager to "End Process". I do not like to do either of these so I usually just sit and wait for it to fix itself then later it does it all over again.
Also when I was doing defrag on the file type tab it showed two Mozilla Firefox so I am wondering if this is the issue but I only see one in the control panel.

Firefox 8.0.1 will not open. IE will not open as long as Task Manager shows firefox process is running.
