My add-ons aren't working after I updated Firefox

I updated FF a week ago and my add-ons haven't worked since. They aren't in the browser, but they are in the list on the add-ons in the tool bar. When I try to click on 'Options' on one of the add-ons, it just freezes and doesn't do anything. I end up having to use the Task Manager to close FF. I also clicked the 'Find Updates' button on the Add-On thing, but there weren't any updates.
The only thing I noticed that are missing are my add-ons on the browser. Not my history, bookmarks, or anything else.
The most noticeable changes are my Session Manager and AdBlockPlus. I can't get to my previously saved session and that's a big bother. Watching ads on YouTube isn't very fun either.
I tried to do what's here https://support.mozilla.com/en-US/kb/Unable%20to%20install%20add-ons#w_corrupt-extension-files and delete extensions.ini, extensions.cache, and extensions.rdf
but there isn't the file extensions.ini for some reason..
None of the add-ons are disabled, and I tried to disable all of them and try them one by one, but it didn't work at all. I disabled all of them, then tried AdBlock Plus and it didn't work, so I don't think one of my other add-ons are causing the problem.

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]]

I can't open new windows and add-ons aren't working.

I recently scrubbed my hard drive due to virus issues in order to contain the virus before it spread. After installing Firefox I noticed that I was unable to open new windows, links that normally opened a new window for Firefox weren't working, and I can't access plug-ins like AdBlock Plus which I used frequently before. I've never had this problem before. I turned off all security settings and unplugged from the internet to see if that was the problem, but that didn't work. I also tried uninstalling and reinstalling Firefox, same deal.

Hello Anand, '''Try Firefox Safe Mode''' to see if the problem goes away. [[Troubleshoot Firefox issues using Safe Mode|Firefox Safe Mode]] is a troubleshooting mode that turns off some settings, disables most add-ons (extensions and themes).
If Firefox is open, you can restart in Firefox Safe Mode from the Help menu:
*In Firefox 29.0 and above, click the menu button [[Image:New Fx Menu]], click Help [[Image:Help-29]] and select ''Restart with Add-ons Disabled''.
When the Firefox Safe Mode window appears, select "Start in Safe Mode".[[Image:Safe Mode Fx 15 - Win]]
'''''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]] article to find the cause.
''To exit Firefox Safe Mode, just close Firefox and wait a few seconds before opening Firefox for normal use again.''
When you figure out what's causing your issues, please let us know. It might help others with the same problem.
thank you

Many add-ons do not work when upgraded to Firefox 3.6.10 on mac

After upgrading to v3.6.10, my Firefox kept on crashing when I attempted to open the app. I had thought that it could be a particular wrong move to install a recently-added new plug-in iMacros to the browser.
However, after around 8 attempts at reinstallation with individual plugins/add-ons (eg. Xmarks, etc), Firefox was unable to startup. From my attempts, I believe it might be some error with the new version that might clash with the other plugins that were previously installed.
I hope some solution can help solve this problem as I would like to try out the new 3.6.10, but since I don't have the previous installer, I have to resort to using a back-dated 3.5.5 version of Firefox.

Glad to hear I am not alone in this. Same time frame too. But at 11 pm on 15.10 equally suddenly firefox started working again, and now seems fine.
Errr?
(glad I have Safari to fall back on)
The aspxerrorpath has disappeared from the header.
Hey, Firefox, what is going on ?

Add-ons manager not loading since I updated Firefox yesterday,right?

I updated Firefox yesterday when the update was offered. Now the add-ons manager (accessed from the tools menu) hangs. It says loading and the icon spins, but it never completes the load. I am running on a Mac. Thanks.

This fix is not working for me. It just spins and spins and I cannot see my Add-ons list. It is difficult to imagine why clicking 'Get Add-ons', which sets off a process requiring interaction with a remote database, should cure a problem with the Extensions list, which presumably sits locally.

Internet download manager and adobe pdf add ons aren't working with FF4, but was fine with 3.6

I updated from ff3.6 to 4.0. After which the ff extensions of IDM 5.19 (internet download manager) and adobe pro pdf maker, were found to be incompatible. Any solutions?

1) When I go to the apple.com website my computer will either be really slow or freeze my whole system down to where I have to reboot my computer again. This does not happen all the time but when it does operate it is molasses slow.
By any chance, are you uswing Kaspersky security software?
If so, see:
[With Kaspersky Internet Security 2011 installed on my computer the website apple.com is imaged incorrectly. What should I do?|http://www.kaspersky.com/support/kis2011/all?page=14&qid=208282422]

My entire bookmark bar is GONE and I cant even add new ones, this happened after I updated Firefox. Can I unupdate? Or is there a way to get the bookmarking function back?

I just updated to 3.6 and I cant go back a page either. It's like it cant remember ANYTHING! I really need help! I have a mac o sx. The space where the bookmarks used to be is still there but it's blank.

This can be a problem with the file places.sqlite that stores the bookmarks and the history.

After upgrading to 20.0.1 cannot open a new window (CTRL+N) and no add-ons seem to work (apart from adblock plus).

Unable to open new window (but able to open new tabs).
Sometimes unable to open Add-ons tab.
The add-on extensions do not seem to be working, even though they seem to be ENABLED (except adblock plus).
When restarting in safe mode, or disabling ALL add-ons the browser works normally, thus new windows open, add-on tab opens etc.
Tried to enable one thing at a time, but it seems that when enabling WHICHEVER TWO add-ons, firefox starts acting "weirdly" (no new windows etc.).
Tried disabling hardware acceleration, but it didn't solve the problem.
Tried uninstalling firefox and then reinstalling. At first it all seemed working perfectly well: new windows opened, extensions working etc. But after a couple of restarts (of firefox and computer) it all got back to the same situation.
Tried uninstalling ALL add-ons and everything worked well. After installing the SECOND add-on and restarting firefox things get "wrong" again.
It all started after upgrading to Firefox 20.0.1.

Hello,
The Reset Firefox feature can fix many issues by restoring Firefox to its factory default state while saving your essential information.
Note: ''This will cause you to lose any Extensions, Open websites, and some Preferences.''
To Reset Firefox do the following:
#Go to Firefox > Help > Troubleshooting Information.
#Click the "Reset Firefox" button.
#Firefox will close and reset. After Firefox is done, it will show a window with the information that is imported. Click Finish.
#Firefox will open with all factory defaults applied.
Further information can be found in the [[Reset Firefox – easily fix most problems]] article.
Did this fix your problems? Please report back to us!
Thank you.

FF29 fails to load Session Manager, old tabs, any add-ons, Cool Preview, etc after upgrade on XP

FF29 fails to load Session Manager, old tabs, any add-ons, Cool Preview, etc after forced upgrade on an XP system. Connecting to sites, especially support.mozilla.org requires numerous retries. Clicking Add0on shows none of the previous working ones. They are gone. No Session Manager at all. Even reporting this has taken over 3 hours. Yesterday, everything worked fine before the restart to 29. What can be done to recover settings from 2-3 days ago? Thanks for keeping it simple!

Thank you for your question. Once history is gone, there is not a big chance of getting it back. However there are some places to check. For next time, try to backup your profile [http://kb.mozillazine.org/Profile_backup].
The crash reports from your troubleshooting information is caused by a hang in the Flash plug in version 13. I understand however that this is an issue with the history.

Download helper add-on no longer works after update of firefox, what has changed?

After I updated Firefox to 18.0.02 the download helper stopped working on 98% of the websites I watch TV programs on. What has changed and will it be returned to its previous condition?
The website I go to is: http://www.free-tv-video-online.me/internet/

Are you using an add-on as a download helper?

URL Bar disappeared, and Add-ons aren't coming back.

Hi Folks. Once again Firefox is making me mad, I woke up this morning, turned on the old computer, started Firefox, and I have no URL bar. I've been trying to restore it, but no luck. Been searching the Firefox forums for a few hours, found similar questions, but ...no cigar. I have version 36.0.4 of Firefox. Can someone please explain how it disappeared and how to get it back?
I uninstalled FF, fully. And re-installed it. URL bar still gone. Also, I signed in to my SYNC, but my add-ons aren't coming back either.
I would appreciate your help.

Do you still have the Navigation Toolbar visible with other toolbar buttons and the Tab bar?
Make sure that you do not run Firefox in full screen mode (press F11 or Fn + F11 to toggle; Mac: Command+Shift+F).
*https://support.mozilla.org/kb/how-to-use-full-screen
If you are in full screen mode then hover the mouse to the top of the screen to make the Navigation Toolbar and Tab bar appear.<br>Click the Maximize button (top right corner of the Navigation Toolbar) to leave full screen mode or right-click empty space on a toolbar and choose "Exit Full Screen Mode" or press the F11 key.
Try to rename (or delete) the xulstore.json file in the Firefox profile folder.
You can use this button to go to the currently used Firefox profile folder:
*Help > Troubleshooting Information > Profile Directory: Show Folder (Linux: Open Directory; Mac: Show in Finder)

"Tools Add-ons" no longer works. I was running 16.0.2, I have just now been upgraded to 17.0 for some reason.

(This is a repost of my question. I reposted as all the formatting was lost and now it's a mangled mess that is hard to read.)
I opened "Help > About Firefox" to check which version I was running.
It said 16.0.2 and "You are currently on the release update channel."
Then while I was watching it upgraded to 17.0.
1. Now "Tools > Add-ons" no longer works.
2. I thought 17.0 was a beta. If so why did it download it when I'm on the '''release''' channel?
3. when I go to http://www.mozilla.org/en-US/firefox/fx/ and click the big green "Firefox Free Download" button it downloads this 16.0.2 version:
http://www.mozilla.org/products/download.html?product=firefox-16.0.2&os=win&lang=en-US
which again implies that I should be on 16.0.2, not 17.0
Thanks!

Tab Mix Plus 0.4.0.3 is the culprit

Delete the files extensions.* (extensions.rdf, extensions.cache, extensions.ini) and compatibility.ini in the Firefox [[Profiles|profile folder]] to reset the extensions registry.

FireFox 3.6.9 Add-ons window not working, add-ons not loading

After upgrade add-ons do not load.
In Add-ons window, no data; all add-ons disappeared;.
Also clicking < Browse all Add-ons > produces nothing, does not link to site.
Navigate toa site to download an add-on: Add-ons window appears but no data or appearance of files or anything. So< Install> button therefore does nothing.

You can delete the files extensions.* (extensions.rdf, extensions.cache, extensions.ini, extensions.sqlite) and compatibility.ini in the Firefox [[Profiles|profile folder]] to reset the extensions registry. New files will be created when required.
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.

Is there a way to see which of my add-ons will be disabled when I install Firefox update?

I have recently returned to Firefox after a long absence. The reason I stopped using it in the first place is that every time I got all the add-ons that I wanted, there would be a new update and I'd lose some or all of them and I wasn't interested in having some/all of my useful functions disabled until who knows when or forever.
I've currently got automatic updates turned off, and that is where they will stay unless I can verify that the add-ons are backwards compatible or there is an update for the add-on.
Is there a way to see what current add-ons will be disabled with an update?

Yes, during the update there is a list of add ons that come up that will not be added when you update. You can cancel the update if it lists one that you do not want to no longer use.
The block list is also here: [https://addons.mozilla.org/en-US/firefox/blocked/]
