Firefox freezes when i click add ons options

Also NONE of my add-ons are working... they dont do what their supposed to do. No add on i download works, i have firefox 7.0.1.
For example these are some add ons i downloaded, Firebug, Personas, ImTranslator, Download helper. (Basicly when i click on options on any add on it freezes and doesnt do anything and I cant do anything on firefox so i have to close it with Windows Task Manager.

Delete the files extensions.* (extensions.rdf, extensions.cache, extensions.ini) and compatibility.ini in the Firefox [[Profiles|profile folder]] to reset the extensions registry.
See "Corrupt extension files": http://kb.mozillazine.org/Unable_to_install_themes_or_extensions
If you see disabled extensions that are not compatible on the next start in "Tools > Add-ons > Extensions" then click the "Find Updates" button to do a compatibility check.

Firefox crashes when opening "Extras Add-ons"

Firefox crashes when opening "Extras>Add-ons" (German user interface - I don't know what the according menu points are labeled in English).
The crash seems to be so severe that no crash ID is created. On every restart after a crash Firefox 4 is in offline mode and has to be switched back to online mode. If needed I could provide a screenshot of the error message shown when firefox crashes.
There were no problems on this machine running firefox 3.xx. The problems occurred after upgrading from firefox 3.6x to firefox 4.

Start Firefox in [[Safe Mode]] to check if one of your add-ons is causing your problem (switch to the DEFAULT theme: Tools > Add-ons > Themes). 
See [[Troubleshooting extensions and themes]] and [[Troubleshooting plugins]] 
 
If it does work in Safe-mode then disable all your extensions and then try to find which is causing it by enabling one at a time until the problem reappears. 
You can use "Disable all add-ons" on the [[Safe mode]] start window to disable all extensions. 
You have to close and restart Firefox after each change via "File > Exit" (Mac: "Firefox > Quit"; Linux: "File > Quit")

CPU usage goes off the meter everytime I start firefox and when I open add-ons tab to troubleshoot the CPU usage goes and then stays on normal.Why?

The CPU usage is 99% everytime I start firefox. When I open help tabs in the browser to troubleshoot the problem the cpu goes down to normal.How am I supposed to troubleshoot the issue if the last resort is as simple as uninstalling firefox?

Hi musicfan, Sorry you are having problems with Firefox. Maybe you should have asked earlier and we could have fixed it.
Reading your comments I do not see that rolling back to an insecure Firefox 22 will actually help you much. You are probably best using IE, unless you have also damaged that.
*[[Export bookmarks to Internet Explorer]]
You should not use old versions they are insecure. Security fixes are publicised and exploitable.
* [[Install an older version of Firefox]]
* https://www.mozilla.org/security/known-vulnerabilities/firefox.html
Most others will not be having such problems. We are now able to say that with confidence because after developers missed a regression in Firefox 4 telemetry was introduced so that data was obtained. It may be an idea to turn on your telemetry, if you have not already done so, and decide to stick with Firefox.
*[[Send performance data to Mozilla to help improve Firefox]]
Trying safe mode takes seconds. Unfortunatly if you are not willing to do even rudimentary troubleshooting there is not anything we can do to help you.

Firefox freezes when I access my add-ons page.

Firefox freezes when I access my add-ons page. I must use Task Manager to unfreeze it. Some add-ons (AdBlock) still work. Others (NetVideoHunter) don't. I would like to remove all the add-ons and start fresh, see if it makes a difference, but when I access my add-ons page to press the "Remove" button, FireFox freezes--so what am I supposed to do? I like Firefox because it's simple and generally glitch-free--until now.

hey furdeal - if you'd like a fresh start, you can simply [[Reset Firefox – easily fix most problems|reset firefox]]. this will keep your bookmarks, passwords & history but will remove all extensions and custom preferences...

Why does plugin box freeze up when I click on an options tab for an addon?

''locking as a duplicate - https://support.mozilla.com/en-US/questions/794712''
Win 7/ 64bit. When I click on the options tab for an addon the box freezes up. The X in the upper right will not work. I have to to go windows task manager to end the box. But the firefox browser works fine. Its only when I hit the options tab for an addon. I can disable, install, or uninstall with no problems.

In synk, when I click "add device" instead of opening a window to enter the codes, it opens another firefox window and takes me to the help page for synk. [SOLVED]

I got a new laptop today and after downloading firefox I tried to use the synk feature and it says I have to add device on my old computer. In following the directions I never get to the screen to enter the codes from my new computer onto the old one. When I click add device on the old computer it takes me to the help page on the web with the same directions that took me there in the first place! So, how am I supposed to synk my new computer if I can't add device on the old or simply log in to my synk account on the new?

Ok, I figured it out, I clicked "i don't have device available" and it let me log in to my account.

How do I add an iCloud account to my "Messages" if the only options it gives me when I click "Add Account" is Google, Yahoo, and AOL?

I want to add another I cloud account to my Messages, But when I Click add account, the only options it gives me is Gmail, Yahoo, and AOL. But I have an iCloud.com email. What do I do in this case ?

Hi rarellano1,
In order to have an iCloud account available for the Messages application it must first be set up in System Preferences > Internet Accounts. If this is a second (or later) iCloud account, it will not have Messages available. See this article for details -

Thanks for using Apple Support Communities.

Graphical errors. The Address dropdown box is blacked out, and goes normal when highlighted, tabs are blacked out, buttons are half missing etc etc. This ONLY happens in firefox, reinstalled and turn all add-ons off and it persists.

Have you tried Firefox Safe Mode to see if an Add-on is causing your problem?
#Use Firefox Safe Mode to find a problem with an Extension or Plugin:
#*Don't check anything when entering Safe Mode, just continue
#*If the problem does not occur in Safe Mode it is probably and Extension or Plugin causing the problem
#*See:

Firefox freezes when ctrl + enter is pressed simultaneously

Firefox freezes when ctrl + enter is pressed simultaneously.

Hello,
Try Firefox Safe Mode to see if the problem goes away. Safe Mode is a troubleshooting mode, which disables most add-ons.
(If you're not using it, switch to the Default theme.)
* On Windows you can open Firefox 4.0+ in Safe Mode by holding the Shift key when you open the Firefox desktop or Start menu shortcut.
* On Mac you can open Firefox 4.0+ in Safe Mode by holding the option key while starting Firefox.
* On Linux you can open Firefox 4.0+ in Safe Mode by quitting Firefox and then going to your Terminal and running: firefox -safe-mode (you may need to specify the Firefox installation path e.g. /usr/lib/firefox)
* Or open the Help menu and click on the Restart with Add-ons Disabled... menu item while Firefox is running.
Once you get the pop-up, just select "'Start in Safe Mode"
If the issue is not present in Firefox Safe Mode, your problem is probably caused by an extension, and you need to figure out which one. Please follow the [[Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems]]
To exit the Firefox Safe Mode, just close Firefox and wait a few seconds before opening Firefox for normal use again.
Please report back soon.

Firefox freezes when saving, printing, or otherwise opening "sub-windows"

Firefox freezes when I open a window to save, print, etc. - not always, but far too often. If I dare try to choose another folder in which to save, I'm even more likely to make it freeze.
When it happens for the first time after opening Firefox, I can often wait several minutes, then it unfreezes, and I can then do one or two more clicks (e.g., scroll, save, etc.) before it freezes again. Otherwise (or the next time, if I didn't restart Firefox in the meantime), the program just gets completely unresponsive, and I have to close it via the Task Manager. So there's unfortunately no error message, crash ID, etc.
Possibly related: When I'm using Firefox for a while (with many Firefox windows open), I'm often not getting menus displayed anymore, just the outline of the menus. The program still reacts to clicks into the outline, but it's like driving blindfolded... Menus include those from the menu bar, those from right-clicking into a website, or those from Adblock Plus (icon in the bar, at the right bottom of each window).
I'm currently still using 3.6.13 (with Adblock Plus) on a Windows 7 (x64) machine. The problem has persisted long before I've updated to this or previous Firefox versions... possibly since I've been using it on this computer (= summer 2010), but I'm not sure. I should add that I *am* using Firefox with lots (!) of Firefox windows open simultaneously, and I often let my computer hibernate rather than shut it down every single time I walk away... but I've been doing that for at least 5 years now (using tons of Firefox windows even much longer, still with Windows 95 or 98), and the problem is new. And limited to Firefox. (Indeed I can even open pages, on which Firefox has just crashed, in Internet Explorer or Opera, and then peacefully save, print, etc. there.)
I'd prefer to keep Firefox as my standard browser, but the problem is getting too annoying! Thanks for your help!!

Hi Susan,
The Adobe plugin in Internet Explorer is a bit different from the one in Firefox, however they're all made by Adobe and they usually come with Adobe Reader.
When you open a PDF file in Firefox, it "calls" Adobe Reader to help it read the file. In this case, the Adobe Reader takes over, and it is responsible for freezing your browser.
I suggest you try the last 4 solutions presented on the [[Opening PDF files within Firefox]] (start with "Re-install the plugin" through "Re-install Adobe Reader").
Good Luck :D

Since installing Firefox 4 Beta 5, the Add-Ons manager is empty. My add-ons still appear to be installed and working, but I can't install more, or uninstall, or configure them.

My add-ons still appear to be installed and working, but I can't install more, or uninstall, or configure them.

Try forcing Firefox to rebuild the list of installed add-ons.
# Open the profile folder, for details of how to access it see the [[profiles]] article.
# Close Firefox, then delete extensions.sqlite (you can also delete extensions.cache, extensions.ini, extensions.rdf if they exist)
When you restart Firefox the list of installed add-ons should be rebuilt.
If that did not work, you may have an add-on that is causing the problem, try the options in the [[troubleshooting extensions and themes]] article.
If you type '''about:addons''' into the location bar does that bring up the list of add-ons? I have seen a blank add-ons list if Mr Tech Toolkit add-on is installed, accessing the add-ons manager by typing about:addons in the location bar is a workaround with that add-on installed. The author of that add-on is working on an update.

Firefox 14.0.1 Get Add-ons stuck on "Loading"

I just purchased a new computer and, in utter spite of Internet Explorer, have downloaded trusty ol' Firefox. Unfortunately, the Get Add-ons is stuck with a bubble that says "Loading" but never actually does.
I am using Firefox version 14.0.1, downloaded directly from the Mozilla site. I have let the thing load for almost an hour, and nothing has happened. I have tried clicking on "Extensions" or "Appearance", etc. but it hasn't helped. Every time I go back to the Get Add-ons tab it will simply say "Loading." I have also tried doing a search for a specific add-on, only to get the same thing, but in the "Search" tab.
I have also tried rebooting the computer, rebooting Firefox, and uninstalling and reinstalling Firefox (i kept my preferences, etc. when I did this).
Does anyone have any suggestions? I really love Firefox and I hate to think that I would have to find another browser to use because I can't download Adblocker Plus.

Only had to remove the extensions.sqlite, and it fixed the problem perfectly. Thank you very much.

Firefox freezes when I go to Youtube videos

As of yesterday, I cannot visit any Youtube video pages. The home page is fine, but whenever I try to go to any page with a video, Firefox freezes completely. I have Flashblock installed, but that doesn't seem to make any difference. I've tried uninstalling Flash and reinstalling to 10.3 - no difference. I'm running WIndows XP, FF 18.0.2. Does anyone know why this might be happening? I don't have this problem with any other browser, only FF.

I just removed [https://addons.mozilla.org/en-US/firefox/addon/video-downloadhelper/ Video DownloadHelper 4.9.15] add-on and voila, Firefox doesn't freeze anymore. If you have it you better remove it. It worked for me maybe it will work for you!
I think you know how to remove an add-on but if you don't, read below:
*In order to uninstall a possibly unwanted extension, please do the following:
#From the Firefox window click the Firefox button at the top left and select ''Add-ons'', or, if the Firefox button is not shown, click the ''Tools'' menu and click ''Add-ons''.
#Once the Add-on Manager has opened in a new tab, click the ''Extensions'' button on the left side of the window.
#You should now see a list of your installed extensions on the right side together with buttons on the right side of each extension.
#To remove an extension from Firefox, simply click the ''Remove'' button. You should see a message that informs you about the successful removal of the add-on.
#Note that some add-ons require a Firefox restart to be removed completely. To perform a Firefox restart after the add-on removal, click the ''Restart now'' link in the message.
*You can find further information about uninstalling extensions in the following articles: [[Disable or remove Add-ons]]

None of the stuff in " http://kb.mozillazine.org/Locked_or_damaged_places.sqlite " helps. I have tried and tried and I have even wipe the computer clean still didn't help. I got the same problem as he/she has got in the first posted. Can add some web pages but not all the web pages I want.. I should have never updated to 3.6.13... That's when it all started for me, from that version..... Now Version 3.6.14 is out, I was hoping the version 3.6.14 might would fix the problem wrong again....
Funny thing is i can not even Bookmark Firefox.com!!!!!...lol
So any ideas on how to fix it other than the link giving would help.
Thanks.

Screen turns white and freezes when I click on a link

also freezes when I click on the screen or try to use the right slide bar. Also getting firefox is not responding.

First, make sure that Firefox is set as the default browser. Ref: [[How to make web links open in Firefox by default]] and [[Setting Firefox as the default browser does not work]]. If links in Outlook Express that should open Firefox freeze the entire computer, you could try temporarily setting Internet Explorer (or another browser) as the default (see http://kb.mozillazine.org/Default_browser#Using_Set_Program_Access_and_Defaults for one way to do that).
If clicking links in Outlook Express still freezes the computer, you should seek help in a Windows XP forum or an Outlook Express forum ... for example, I found these with a google search:
*http://answers.microsoft.com/en-us/windows/forum/windows_xp-networking/outlook-express-6-causing-computer-to-freeze/75fb3e15-0934-4fb9-888b-3d82d6c7ae10
