My firefox stops responding and fades for about a half min almost every hour, OR MORE often

My firefox stops responding and fades for about a half min almost every hour, OR MORE often.
I am typing a message or information, the screen fades to about half bright. the curser freezes in place and no key responds.
The information bar at the top of the page says "firefox not responding" in about 30 seconds it restores and continues as tho nothing happens.

I might have discovered the solution without starting over with all your places and bookmarks.
Right after i installed 7.0.1 over a week ago,every 10-30 min When i would be watching videos online, it would freeze for 20-30 seconds. Firefox would say ( Not responding) both firefox and the plugin container process would be very large memory files. I tried to go back to Firefox 5.0. No avail it would still freeze.I tried to disable the plugin container . no good. I tried to adjust memory or cache or plugin settings in “about:config”.Nothing fixed it!
I finally discovered why my Firefox 7.01 was periodic hanging fix. It is something to do with some of your personal files. download this this add on and install it
https://addons.mozilla.org/en-US/firefox/addon/places-maintenance/
or you can Google "places maintenance Firefox"
After you install the add on, restart Firefox.go to "tools", then "add ons" and then click “extensions” tab ,then click' options" on the "places maintenance" entry. choose "ALL' or just "expire" and hit "execute", then wait until its done., restart Firefox. should be fine then and all my bookmarks, customizations ,settings, and history stays untouched!
After i did this my Firefox did not freeze once for over 3 days straight. Might not work for everyone. I already read that Mozilla is aware of the problem and are working on a fix it in the full version of 8( the 8 beta did not fix the problem for me) . But they said this is a good temporary fix at least,( might be permanent)
For me at least ,Firefox works fine in 7 now. perfect actually.And many people i saw on similar forums had similar problems.
Enjoy. Hope this helped

Very often Firefox stops responding and freezes for about 15 seconds and then resumes

Whether I am on a particular website, searching or playing games I keep getting the screen freezing and at the top bar it says "Not Responding" - this will clear on its own after about 10-15 seconds but then 5-10 minutes later it happens again!

The default of the pref network.http.max-connections has been increased from 30 to 256 in Firefox 6+ versions.
Try to decrease the value of the pref network.http.max-connections from 256 to 30 as used in Firefox 3 versions.

Ever since the most recent firefox update, every time I try to download anything firefox stops responding and will not do anything until I restart it. Can I revert back to a previous version, or is there a fix for it?

Every time I try to download anything firefox stops responding and will not do anything until I restart it. Can I revert back to a previous version, or is there a fix for it? When I restart firefox, then the download continues and all is well until I try to download something new (which I do quite often).

You may well find this article of interest and help in sorting out your problems: [[Installing a previous version of Firefox]] The article does contain a link for previous versions, but also points out other troubleshooting advice that may be more appropriate in some instances.
Another useful article is [[Basic Troubleshooting]]
I hope you sort out your problems either by downgrading or finding the cause of the problem.

When I try to view my full att bill firefox stops responding and closes ALL pages. I have to open explorer to view it!

I am trying to view my ATT wireless bill, and when I ask to view the full version it opens another window and says receiving data from ATT. This doesn't ever change and when I hit any key on any other window in firefox then I am told that firefox has stopped responding and must close.

No release of Pages v5 can open AppleWorks, Pages '05, Pages '06, Pages '08, or RTF documents. Sometimes, it cannot open its own documents.
You will need to do one of the following:
Borrow your MacBook Pro back until you can export all your incompatible documents to MS Word (Which Pages v5 can open)
Install your iWork '08 DVD on your new Air, and then immediately apply the following Apple Updaters. Again Export to MS document formats.
Pages v3.0.3
Numbers v1.0.3
Keynote v4.0.4
Purchase iWork '09 DVD, and then immediately update with Apple iWork 9.3 updater.
Open the document(s) that Pages v5 won't permit
Save as Pages '09 v4.3 documents, or export as MS Word
Upload to Zamzar, and convert to MS Word (free for limited volume)
No sensitive documents
Email notification within 3 - 4 minutes with MS Word document download link
After you do either item 2 or 3, run Disk Utility and verify/repair application permissions on your boot drive. Open your converted documents in Pages v5.

When I enter the website, Firefox stops responding and I have to end the process from the Task Manager. How do I solve this problem?

I am running Firefox 4.0 beta 7 on Windows XP Tablet Edition OS. When I enter this site using Firefox, the browser stops responding and I have to end the process using Task Manager. However, when I open it with other browsers such as IE8, I am able to view the site as per normal. This only happened when I updated my browser to Beta 7 and I did not have such problems in the previous betas.

There is [[Flash]] content on that page.
Do you have a problem with Flash on other websites?
Create a new profile as a test to check if your current profile is causing the problems.
See [[Basic Troubleshooting#Make_a_new_profile|Basic Troubleshooting: Make a new profile]]
If that new profile works then you can transfer some files from the old profile to that new profile (be careful not to copy corrupted files)

Firefox stops responding and crashes

My tablet is an Asus tf300t with an Android 4.02 OS. I really like what Firefox has to offer, but it is not working for me. I am even writing this on Chrome because Firefox would stop responding constantly.

[[Will Firefox work on my mobile device?]] is for Firefox for android and the is a requirement that ARMv7 should be compatible. However I would recommend filing a bug in bugzilla.mozilla.com with the about:support information if you can open it.
They may also ask you to provide this info if you have a device that can be accessed by the sdk [https://developer.mozilla.org/en-US/docs/Tools/Remote_Debugging]

Firefox stops responding and some times dose not start when clicked on alot!

fire fox 9 stops responding for long periods and some times dose not load when clicked on. Also please note fire fox refuses to load the comments section on Yahoo.com under the news tab. The little wheel on the bottom of the page just spins and spins and never loads this area of the page.
I think i know why but wonder since i have had issues with fire fox in the past with the whole not responding and load issues.

Firefox which stops responding after some time is a BIG problem. You're not the only one. The problem seems to be with sites which require Java. The problems I seem to have spotted is this : You visit a web site which needs Java so Java asks Firefox for the amount of memory needed and this is lent to JAVA. However, when you leave that web site, Java is naughty in that it doesn't give back the memory borrowd. Firefox then has to consume a lot of memory to the point that the whole computer system grinds to a halt as you have run out of memory.
Search in the forums for high memory or RAM and you will see many threads. In fact, when you first install Firefox it will ask if you want to send anonymous data about the memory usage!!

After Updating to Firefox 4.0, many of my regularly visited websites now load very slowly or Firefox stops responding and does finish loading the website.

Typically, the splash page will lode partially but as soon as it starts to transfer data from ad related sites (ie doubleclick) , Firefox seems to stop working and when I when I try to close the site, I get a FireFox - Program is Not Responding message. I tell the computer to End Program and it takes 3-4 minutes for Firefox to close> When I then reopen Firefox, I get a message saying (This is Embarrasing_ we couldn't find some of your tabs. Firefox then offers me the option of restoring the previous session or starting a new one.

I have to agree, a once rapid firefox is now an absolute pain, I have scanned the computer with Malware bites and AVG nothing found..anybody got the fix?

Intermittently and without obvious pattern, Firefox stops responding and, after being closed via task manager, will not reopen unless I restart my computer.

Firefox 5 stops responding after I use it for awhile. Once I close it through the task manager, it refuses to reopen and I am forced to restart my computer to get Firefox to work again.
Note: This problem also occurred in Firefox 3 before I updated.

Try running Firefox in [[Safe Mode]]. If it functions properly in that configuration, then one of your add-ons is the culprit.

Since installing the latest update firefox stops responding and hangs during use.

The only way I can get it to work is to shut it down and restart the application. I can open IE and access the sites which don't respond so it is definately a firefox problem. All firefox tabs stop responding including downloads. This is occurring every 2nd or 3rd page I open. Help - it's driving me insane!

See:
* http://kb.mozillazine.org/Firefox_crashes
* https://support.mozilla.com/kb/Firefox+crashes

On any page that I have to log in Firefox stops responding and has to shut down. I've tried resetting it and it still doesn't work.

I've been having this problem for a while now and I can't seem to fix it. Any time I log into any page, Firefox says not responding and I have to restart it. I have to run all of firefox in safe mode if I log out of my email or facebook. I've tried resetting FF and it still doesn't work.

''' "I have to run all of firefox in safe mode if I log out of my email or facebook. " '''
Please explain what you mean by '''all of firefox'''. You're either running in the Firefox SafeMode or you're not. There's no "all" or partial SafeMode.
Please see this: https://support.mozilla.org/en-US/kb/troubleshoot-firefox-issues-using-safe-mode

Firefox stops responding and causes Windows to stop responding also

Sorry if this is vague; I just wrote a very, very detailed post on my issues but then the site decided that I didn't have permission to post it and erased everything.
My problem is that Firefox freezes and causes Windows to freeze for a while also. after a few minutes it goes away, but today I got the following error message:

I noticed the file "mswsock.dll" mentioned so I looked for issues with it. Apparently there are issues with malware and Firefox and that file. I have scanned and it found nothing, plus this issue has existed in three formats of my drive and windows re-installs (for other reasons, I didn't format and re-install just to make sure there was no malware) so I'm pretty sure there are no problems with malware.
I am running a Minecraft server and I have a static IP set up, but I've been doing this for three years without issues so I don't think that's the issue either.
I have tried disabling all plugins. Still crashes and crashes Windows with it.
I have run Memtest86+ and the windows memory tester. Not a memory issue.

I can't be the only one having this Finder issue: Finder stops responding and requires relaunch about every third time I open it.

I have a brand-new MBAir, but I actually noticed this starting many months ago, on my MBPro running Snow Leopard. I've repaired Permissions numerous times, run Onyx and performed all of the scans and checks (everything checks out fine), and otherwise have no problems at all with my system. It's just this constant need to relaunch the Finder, especially after downloading a dmg. In-between these episodes it seems to behave normally.
I though it was a Snow Leopard problem, and was hoping it would be gone with Lion, but, alas--no such luck.
I've searched through the discussions and support docs and haven't found anything similar--can I possibly be the only one with this weird issue? I've been a Mac User for over 20 yrs, and can't say I've ever seen this particular problem before....Does anyone have any thoughts? Thanks!

OK, Tony--did that. I noticed that it had a creation date of 2009. Wouldn't a new OS create new plist files, or do all of the old ones just migrate over from the previous OS? Interesting....
Anyway, I'll just have to wait and see if it happens again--shouldn't have to wait too long--LOL. I'll post back with an update ASAP.
Thanks for your help!

Firefox stops responding after file download

After I download a file, Firefox stops responding and I have to wait for around 10 seconds before I can use it again.
This also happens when I'm using "Download them all"

That can be a problem with your AV software. Firefox let your default anti-virus program scan the file after the download has finished.
See http://kb.mozillazine.org/Unable_to_save_or_download_files

When two or more tabs are opened after this when I click on another tab which is opened then firfox stopped responding and open automatically all the tabs in diffreent windows

when two or more tabs are opened after this when I click on another tab which is opened then firefox stopped responding and open automatically all the tabs in different windows

If it works in a new window then you can drags tabs from the not working window to that new window.
You can also try to close the tabs via Ctrl+W and restore the closed tabs via Shift+Ctrl+T

My firefox stops responding and fades for about a half min almost every hour, OR MORE often
