Firefox Suddenly Won't Stop Constantly Freezing

All of a sudden, Firefox is freezing so much for me that it is unusable. It's 3.6 on a Macbook that's a few years old. It's been glitchy for a while, as has my Macbook, but a restart always fixed it. Now it's totally a mess - if I try to scroll, switch, close, or open a tab it freezes for a few minutes or until I just have to shut it off. Safari appears fine.

Firefox 4.0.1 is constantly freezing, having to reboot constantly, and not responding to key strokes, and very slow responses to keys strokes and to change sites

firefox 4.0.1 is constantly freezing, having to reboot constantly, and not responding to key strokes, and very slow responses to keys strokes and to change sites. Firefox 3. (the previous incarnation of firefox) did not have such problems - this has started since "upgrading to 4.0.1 - I want to change back to the previous Firefox since this is a serious problem - need specific instructions on how to go back to the old Firefox

Do you have multiple keyboard layouts installed?
It is possible that you have switched the keyboard layout by accident.
* http://support.microsoft.com/kb/258824 - How to change your keyboard layout
Windows remembers the keyboard layout setting per application and you may have changed the keyboard layout by accident via a keyboard shortcut.

* Make sure that you have the Language bar visible on the Windows Taskbar
* You can do that via the right-click context menu of the Taskbar: Toolbars > Language Bar
* Check the keyboard language (keyboard layout) setting for the application that has focus via the icon on the Language bar

10.6 definitely won't stop random freezing on my MacBook 13"

Hello.
I have a MacBook white I bought two years ago.
When I bought it it already came with 10.5 installed.
A couple months after I bought it I upgraded its RAM from the original 1G to 4G, as well as changed its harddrive from the original 120G to a Seagate 500G.
Nothing stopped working, in fact I thought I had (or still have, hopefully) a very nice machine.
When apple released Snow Leopard I felt tempted to upgrade after looking through the neat new features. I went to the store and bought my copy of Snow Leopard and made an upgrade of my machine.
This is when I started experiencing ****!
From the moment I upgraded to 10.6 my once steady and consistent mac started random freezing and showing me that extremely obnoxious beach ball (a.k.a. beach ball of death).
From September 2009 (when I made the upgrade) until last month (March 2010) I kept trying and digging for solutions to this issue. I tried literally everything I could find in the forums, both apple discussion forums and other mac related forums. From resetting the SMC to doing a fresh 10.6 installation (yes, from scratch).
I'm very unfortunate to say that nothing, nothing worked. The random freezing kept happening on 10.6.
This was when I decided getting back to 10.5.
I even did a full RAM test using memtest (I left it running for a whole day on single user mode) and all tests passed.
10.5 is working nicely so far, I have been testing it full load for a couple of days and no freezes so far.
Now here's my question: why in the world 10.6 won't work for me? I really want it but I can't afford having a Vista like OS in my mac.
Anybody has any clues? Any probing suggestion I might have missed?
Thanks a lot!

Well, I only got to read your reply after exchanging the hard drives.
In any case I got 10.6 freezing with the old HD as well, which is sad!
Regarding the RAM I bought, I got it from a local electronics store and it is supposed to be a kingston module. I never verified the modules in the Kingston website though.
I'll get them off and try to verify the authenticity of the modules with Kingston, and will give a try with the old memory modules.
From the top of my head I can't figure what kind of incompatibility can there be with a working module that has the exact specifications of the macbook I own. In any case, it is worth the check.

Firefox suddenly won't start. I open it on my Mac, I see the Apple icon and Firefox where a menu bar should be, but that's it. My only option is to Force Quit. Firefox windows won't open at all. Any advice?

As you can read above, that's it. The only thing I can think of is that I did a Microsoft update and then my Firefox stopped working. It won't start up. Windows and tabs won't open. It's completely unresponsive. I have uninstalled and reinstalled new and old Firefox, yet I have the same problem.

2. Press + R (click the Windows Start button and select Run... on Windows XP).

Acts the same as trying to open FireFox. Also when reinstalling it said FF was open. The only way to close it was to restart the computer. However when Shut Down button is pushed, FF is not listed as a program that is open.

Hi geneo3711, sorry you are having problems.
There are many possible reasons for problems lets look first at the ones I consider most likely:
In ordinary circumstances Firefox only runs one instance using one profile. If you have Firefox not shutting down properly that may prevent you from starting Fifrefox until you have found and killed the process. (Also look for plugincontainer which may also exist).
If you are certain Firefox is not already running then the problem is often that a Firewall or security related program is blocking Firefox. This is especially likely if you have installed new security software ,a new version of Firefox, or have tried to restore the computer.

Firefox suddenly won't start and I can't open the profile manager; what else should I do?

Firefox was working. When I went to re-open it the wheel spun, stopped, and then nothing. I search online and it said to create a new profile by running firefox.exe -p. But nothing happened. The support article said that perhaps another version of Firefox was running in the background but not visible and to reboot. I did. No difference. I'm stuck. What else can I do?

I tried Safe Mode, but apparently you need Firefox to start regularly and then hit the menu button to get it to start in Safe Mode next time. Unfortunately I cannot get Firefox to start at all.
I'm going to try to save the profile and then re-install Firefox. However, the "Back up and restore" instructions on how to do this are a bit vague. For example, it tells you how to find your profile file by doing a search. But on my computer the search comes up empty (turns out on my computer the file name has the word "local" in the middle of the phrase given in the instructions.

Firefox suddenly won't open at all

Starting yesterday, firefox doesn't open at all. When I bring up the task manager it shows that firefox is running. I've tried ending the process and then restarting, but it still doesn't open. I tried uninstalling and reinstalling. I also tried to create a new profile as one your articles suggested but it won't even open the profile manager.

Why won't Firefox suddenly won't display SoundSlides files -- new and ones displayed in the past? I've cleared history, cookies, etc. Also deleted and reinstall

Firefox will no longer display our university news website news.wsu.edu correctly, AND it will no longer display SoundSlides files that we have posted. See our front page at news.wsu.edu as well as SoundSlides example at http://news.wsu.edu/pages/publications.asp?Action=Detail&PublicationID=32021&TypeID=1
Have tried deleting and reinstalling Firefox. Deleting all history, cookies, etc.

It works ok for me but then I am not using Flash 11.3 on Windows.
I can see http://news.wsu.edu/ ok
When I try http://news.wsu.edu/pages/publications.asp?Action=Detail&PublicationID=32021&TypeID=1. I get a mainly blank page with an error message
Microsoft OLE DB Provider for SQL Server error '80040e07' 
Error converting data type char to int. 
/Includes/SiteIncludes.asp, line 30
Possibly the link is not quite correct. (trailing dot ?)
Selecting a "sound slide" does however work ok for me I get a slide show with very loud music.

'''It appears it works for me. Possibly you have a problem because of Flash Player 11.3 use. You may find it works if you downgrade to FlashPlayer 11.2 or 10.3''' There have been known issues with FlashPlayer on Windows Firefox systems. Developers from Flash & Firefox have been working on the problem, but despite new updates to both FlashPlayer and Firefox in recent days, problems may still be occurring.
Note also there is a related but separate problem on some systems with RealPlayer. If you have Real Player installed please say so, and especially mention if that includes video download or recording options.
The current standard response to the Flash Player 11.3 (Windows Firefoz) problem is as follows, (but advice may change over the next few days):
Recent crashes of certain multimedia contents (this includes Youtube videos, certain flash games and other applications) in conjunction with Firefox 13 are most probably caused by a recent Flash 11.3 update and/or a malfunctioning Real Player browser plugin.

This is the sort of thing that your own IT department may well be able to help offer advice on, and if it is the problem I suspect, then it is likely to impact on many site users.
They may also be interested in the possibility of deploying Firefox ESR for themselves and students.

You can get the latest version of Firefox 3.6 from http://www.mozilla.com/en-US/firefox/all-older.html

Firefox (v. 25.0.1) suddenly won't let me input in Japanese. How do I fix this?

For some reason, Firefox suddenly won't let me input in Japanese. (I am using version 25.0.1.) Why has this happened and what can I do to fix it?

I think this problem relates to an issue that I have raised here:
https://support.mozilla.org/en-US/questions/978034
If so, it is to do with the limiting of input sources to your default device in Firefox 25.0.1. Are you using OSX, and do you have multiple keyboard layouts in your language toolbar drop down?

I downloaded the new Firefox but it constantly freezes, doing absolutely nothing, and I can't even close it from my Mac dock bar, I have to turn off my laptop using the power button as Firefox won't let me shut down. What can I do?

Hi
I recently downloaded the new Firefox (Firefox 4, I think - you can tell I'm very tech savvy!) and it constantly freezes, I can't do anything with it at all - I can't even close it from the icon in my Mac dock bar.
I have tried restarting my computer - though I have to turn it off by using the power button as as Firefox is open and totally unresponsive it won't let me shut down. About a minute after re-starting Firefox, restoring my tabs or starting afresh, it freezes again.
This is obviously very annoying and I'm not sure what I can do about it. Firefox is my preferred browser, and I'd really like to be able to use it again!

This is not a reply. I just want to elaborate on this problem.
My computer freezes occasionally when it is used after being sleep for a while. The spinning ball appears and everything is totally disabled. Nothing on the keyboard works.
The mouse moves, but does not work.
The only solution is to turn the power off and on (losing all data in open applications.)
I kept the System monitor running on the side to find out which program was running when the computer froze. The Monitor as well as all other applications froze, but the data showed:
Firefox 18.4%
Activity Monitor 0.9%
Firefox Plugin 0.2%
This is all the information I have. By the way, I am using iMac with OS 10.6.

Upgraded to Firefox 4.0.1 for Mac, constantly freezes and crashes, have to force quit, bad bugs. Switching to Safari.

I upgraded to Firefox 4.0.1, and it now constantly freezes, won't respond at all, and has to be force quit and restarted. Within less than 5 minutes of use, over and over and over... I'm assuming it is a bug in the Mac version.... Am switching to Safari as I can't waste this much time constantly quitting and restarting and getting my tabs all back up. Any suggestions on ways to let Firefox know about the bug would be greatly appreciated. It worked fine until I upgraded :( Am running Mac OS X 10.6.7

Why do firefox CONSTANTly, again, CONSTANTLY freeze when I am doing things???? It is irritating and needs to be fixed right now. I am always forced to restart and lose whatever I was doing.

Whenever I am in my online school, the site CONSTANTLY freezes up on me. Fix this now.

Please believe that the problem is with your set-up not Firefox.
I think you are going to have to work your way through this(Safe Mode, Problematic Extensions etc) - there is no magic button -
https://support.mozilla.com/en-US/kb/Troubleshooting%20extensions%20and%20themes
Make sure your plug-ins(such as Flash, which isn't) are up-to-date.
For the record, this forum is mostly run by volunteer helpers who are users just like you. All of our Firefox versions are working beautifully.

Since installing 3.6.12, firefox crashes continuously...I have gone back to Windows Explorer because firefox does not run anymore. Upon any actioin in firefox, the screen goes white and freezes and I get an error message saying firefox has stopped working

just about any action in firefox will cause a "WHITE SCREEN" freeze up and then an error message stating that firefox has stopped working. This happens in EVERY sessioin of firefox.

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.

I downloaded version 4.0.1 and it crashed my system- my Norton no longer works and Firefox browser won't open. I did system restore which did not fix it. I tried downloading 4.0.1 again, it freezes when it tries to open "Checking add-on compatibility".

I downloaded version 4.0.1 and it crashed my system, my Norton no longer works and the Mozilla Firefox browser won't open. I did a system restore, which did not fix it. I tried downloading 4.0.1 again, it freezes when it tries to open "Checking add-on compatibility". What the heck is going on??
