My add-ons are not working

My add-ons appear in Tools Add-Ons. They are all enabled. But they are not working, including Greasemonkey. Then, Firefox does not respond and hangs.
What the heck is going on with this new version of Firefox? It is one problem after another. There may be more problems that I have not yet discovered. Is it possible to revert to the old version?

The current version of Greasemonkey is compatible with Firefox 29. Could you check to make sure it is not turned off? There should be a "monkey" icon on the toolbar. Clicking that icon turns Greasemonkey on and off; the "off" state is designated by a faded icon, while the "on" state has a full-colored icon.
More generally, could you check for possible extension updates and disable unimportant extensions in case one of those conflicts with Firefox?
Open the Add-ons page using either:
* Ctrl+Shift+a
* "3-bar" menu button (or Tools menu) > Add-ons
In the left column, click Extensions. Then, look for the "gear" button above the list and choose Check for Updates.
I also suggest disabling any extensions you won't be using for the next 24 hours so that you can test whether that improves Firefox's functioning.
Usually a link will appear above at least one disabled extension to restart Firefox. You can complete your work on the tab and click one of the links as the last step.
Any difference?
One possible reason for hangs, especially where you eventually get a dialog indicating that a script is running slowly, is Flash. To minimize sites from using Flash unnecessarily, try setting Flash to Click-to-Play ("Ask to Activate"). This will delay Flash from starting on a page until you approve it.
On the Add-ons page, in the left column, click Plugins. Look for "Shockwave Flash" and change "Always Activate" to "Ask to Activate".
When you visit a site that wants to use the Flash, you should see a notification icon in the address bar and one of the following: a link in a black rectangle in the page or an infobar sliding down between the toolbar area and the page.
Any noticeable difference?

Adblock add ons are not working upon update to Firefox 15

I upgraded to Firefox 15 with AdBlock Plus and suddenly I am seeing ads and am not able to block anything or add new subscriptions. I reset Firefox and installed AdBlock Lite, but am still experiencing problems with seeing ads. Two days ago, I was not seeing ads and now I am.

Sometimes a problem with Firefox may be a result of malware installed on your computer, that you may not be aware of.
You can try some of the following programs to scan for malware:
* [http://www.malwarebytes.org/mbam.php MalwareBytes' Anti-Malware]
* [http://support.kaspersky.com/faq/?qid=208283363 TDSSKiller - AntiRootkit Utility]
* [http://windows.microsoft.com/MSE Microsoft Security Essentials] (A good permanent anti-virus if you don't already have one)
Further information can be found in the [[Troubleshoot Firefox issues caused by malware]] article.

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.

I want to go back to Firefox 4, where can I find a download of Firefox 4? I will eventually use FF5, but just now too many add ons are not available

where can I find a download of Firefox 4, I feel uncomfortable with FF5 because so many add-ons are still missing, I will eventually use FF5, but right now I want to go back to nr. 4

Try using the Add-on Compatibility Reporter to override compatibility. <br />
https://addons.mozilla.org/en-US/firefox/addon/add-on-compatibility-reporter/
Firefox 4 versions aren't supported by security updates that are included in Firefox 5.0 and Firefox 3.6.18. If you are gonna "go back", use 3.6.18 instead. <br />

Foxfire 6.0 add-ons manager not working, says "loading", get nothing, now what?

Just received an update and some add-ons were disabled. Clicked on "Tools", "add-ons". Tab opens and says "Loading" but nothing loads and I can't do anything with add-ons manager. Is there a fix?

Thanks for the suggestions. When you click on Tools and then Add-ons, theAdd-on Manager launches, and by default "Get Add Ons" is selected. Although I was not getting any response other than "Loading", if I then click on Extensions or Appearance or Plugins, I was getting a proper response from those three. After doing that and closing out Add-ons Manager and then relaunching it, my original problem disappeared. Now everything works fine. I tested it multiple times and is still OK. Can't explain it but OK for now. Maybe the Get Add-ons portion of the Web site was down at the times I was testing it? I'll keep a watch on it. Thanks for your speedy reply.

Adobe acrobat add ons does not work with latest firefox

I have been using firefox because of my adobe acrobat add ons.. I alwasy convert pages to adobe pdf using my acrobat. It works with firefox 4.0 but it does not work anymore with latest firefox.
Can you help me with this?

Maybe if you read about privacy, policy and sharing of data you'd change your mind. But it was reported that it appeared to work if you used something like the "Add-ons Compatibility Reporter".
You can force 5.0 "compatibility" with the "[https://addons.mozilla.org/en-US/firefox/addon/add-on-compatibility-reporter/ Add-on Compatibility Reporter]" extension, or with [http://kb.mozillazine.org/Extensions.checkCompatibility extensions.checkCompatibility] using about:addons.

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 ?

My add-ons are not running anymore after upgrade to Firefox 3.6.13 and the add-on page crashes efey time I open it.

E-mail notifier and weather forecasts are not visible anymore in my taskbar.

Start Firefox in [[Safe Mode]] to check if one of the add-ons is causing the problem (switch to the DEFAULT theme: Tools > Add-ons > Themes).
* Don't make any changes on the Safe mode start window.
See:
* [[Troubleshooting extensions and themes]]
* [[Troubleshooting plugins]]
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, not compatible, extensions on the next start in "Tools > Add-ons > Extensions" then click the "Find Updates" button (in Firefox 4: right-click the extension -> "Find Updates") to do a compatibility check.

Get ADD-ONS window not working

It seems I am installing add-ons ie, ebay sidebar, tweetbeat firsthand, they look installed in the add-on box but are not working at all?

I can go to tools, add ons and choose the add on I want and install it, then restart firefox but although the new add ons show up in the add on list nothing is there, they are not working at all, I am able to click on and change the options but apart from the new add ons do not appear to be there?

Hi,
I actually have the same exact problem with southwest.com. I think they use AJAX to load the airport cities when you're choosing a flight, perhaps. Normally, when you click the box (or start to type a city) in the "From" box, it pops up a list of airports in a floating box (not a separate browser window). Since upgrading to Firefox 3.6.15, this just doesn't work, and it also keeps me from using southwest.com in general. The calendar links for the departure and return dates are similarly busted.
I tried restarting in Safe Mode, and it is still broken in Safe Mode.
I downloaded the FF4 RC, and that version had no problem. If I switch back to 3.6.15 though, it is still broken. I tried it in Chrome and IE7, and southwest.com works fine. It appears to only be broken in FF 3.6.15.
Thanks!

After updating to Firefox 8.01 all my add-ons are disabled & I have to manually reinstall those that still work after each reboot??

After updating to Firefox 8.0 & 8.01 all my add-ons were disabled.
I have to reinstall those that still can be enabled manually after each reboot. These, that I can reinstall, are:
Download Helper 4.9.7/WOT 20111107/Adblock 1.3.10/DivX plus Web Player HTML5 2.1.2.145/
All my other add-ons are incompatible with this version of Firefox! This includes Ghostery which I particularly miss,
This is annoying!

Ghostery: Works with Firefox 3.5 - 11.0a1: https://addons.mozilla.org/en-US/firefox/addon/ghostery/
It is possible that there is a problem with the file(s) that store the extensions registry.
Delete the files extensions.* (e.g. extensions.sqlite, extensions.ini, extensions.cache) and compatibility.ini in the Firefox profile folder to reset the extensions registry.

If you see disabled, not compatible, extensions in "Tools > Add-ons > Extensions" then click the Tools button at the left side of the Search Bar (or click the "Find Updates" button in older Firefox versions) to do a compatibility check or see if there is a compatibility update available.
