I can't remove add-ons in Thunderbird 24.5.0.

On-line instructions say there should be a "Remove" control, but I do not see it.

OK. I got rid of it using the method at the first link, and I also got rid of some other junk that way (Norton, etc.). But the thing that I noticed is that "Plug-Ins" in both TB and FF DO NOT have a remove control - that only exists in the "Extensions" list. I have a bunch of unused extensions I would rather delete than have hanging around, but the only choice I have is the mode of activation (never, always, ask). Am I missing something?

Can't remove add ons from status bar

I added weather apps at bottom status bar after app dissapeared. The new ones take up the whole bar and I don't like it. Now I can't get rid of them.

how did you uninstall that software? did you simply trash the application? that wasn't the proper way to do it since the app used an installer to install. there should be an uninstaller that came with that app. try using that. you might have to reinstall that software first. if that doesn't work then you have to search out what exactly that software installed. there could be login items. check those in system preferences->accounts. or there could be some launch daemons. check homedirectory/Library/Launchagents, /Library/launchagents and /Library/launchdaemons. but definitely try the uninstaller first.

'''Ctrl+Shift+A''' should also open the Addons Manager.

Need to remove add-ons. Instructions not clear and cannot find add-ons in the menu button. Urgent help please!

explained in question

hello leothedc, you can also access the addons manager by typing '''about:addons''' into the address bar.
[[Disable or remove Add-ons]]

How can I delete add-ons - your help advice does not work.

Your advice says click on 'Tools' then 'Add-ons' and it then takes me directly to the add-ons page. There is no option 'Extension or appearance or plug-ins' which I can choose.

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:

I can't open add ons. mac 10.5.8.

Applications/Firefox.app/Contents/MacOS/components/nsExtensionManager.js:623 in English
This is what I get when I try to uninstall persona add ons. I can't open add ons even in safe boot. This started when I used a Corvette persona.

This issue is caused by an incompatibility of Personas Plus 1.6 with the Google Toolbar.

Can you buy add ons with an itunes gift card

Can you buy add ons to a game on iphone5s with an itunes gift card ? Thank you

If you mean in-app purchases, yes, in most cases a gift balance will work. Some apps do not accept gift balances, but I've not heard of a game where that is the case.
Regards.

How do you identify and remove add-ons/extensions

The explanation of how to remove add-ons tells you to click on menu (and then 3 parrelel bars) What menu is that? I figured out(by trying each and every menu until I figured out it was the tools menu. when I get to the last step it says click the remove button. There is NO remove button at that point (just an enable button which is the last thing I want to do. I am talking about the Cinema ploos extension. It represents it's self as an upgrade with many improved features, but all it is is an add bot that is noisy and obnoxious and they want a one time fee (extorsion) to remove it

Can't update add-ons, install toolbars or new add-ons, get desktop shortcut icons to work, delete desktop shortcut icons, or uninstall Firefox! Help!

I have Firefox 3.6.3 running on a Toshiba Satellit laptop with Windows XP. I can't update add-ons, install google and yahoo toolbars, get any of the 3 desktop shortcuts to work or delete them, nor uninstall Firefox to try and start over. What a piece of crap! How can I wake up from this nightmare?

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]]
There may be extensions and plugins installed by default in a new profile, so check that in "Tools > Add-ons > Extensions & Plugins"
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 6 can't open add-ons manager to uninstall yahoo toobar which installed by itself.

Yahoo toobar installed itself on my computer and I can't open Add-ons manager to uninstall it. Add-ons manager window just keeps trying to load but won't load.

Open the Firefox Safe Mode and un-install that Yahoo Toolbar extension from there.

Can't install add-ons or remove old ones

Hello,
I've done a fair few re-installs on my OSX and I'm now running 10.9.5 with Firefox 33, however every time I reinstalled, I copied over my profiles folder to have the saved passwords, history and add-ons already setup.
Recently something strange has been going on, I can't install an add-on, it installs but even after a restart it says it will be isntalled after restart.
I can't delete one, same thing as above, so I had to delete majority of them manually.
Every time I load firefox, it checks for add on compatability, which it didn't do before.
Is this some sort of a permissions issue or? I'd do a fresh install however I need to retrieve my passwords and browsing history first, and only way I know how to do that is with a plugin.
Any help would be appreciated!

It is possible that there is a problem with the file(s) that store the extensions registry.
Delete the extensions.* files (e.g. extensions.json, extensions.sqlite, extensions.ini) and compatibility.ini in the Firefox profile folder to reset the extensions registry.
*https://support.mozilla.org/kb/Profiles
New files will be created when required.
See "Corrupt extension files":
*http://kb.mozillazine.org/Unable_to_install_themes_or_extensions
*https://support.mozilla.org/kb/Unable+to+install+add-ons
If you see disabled or not compatible extensions in "Firefox/Tools > Add-ons > Extensions" then click the Tools button at the left end of the Search bar to check if there is a compatibility update available.
If this hasn't helped then also delete possible addons.json and addons.sqlite files.
You can reset all prefs to have a fresh start and delete possible user.js and numbered prefs-##.js files and rename (or delete) the prefs.js file to reset all prefs to the default value including prefs set via user.js and prefs that are no longer supported in the current Firefox release.
You can use this button to go to the currently used Firefox profile folder:

Can't uninstall add-ons.

I know this question has been asked numerous times before, but nothing I've found has been able to help me. It also doesn't help that the search results are a bit pathetic in my opinion when you're trying to solve things on your own.
Having said that, I have two issues which I think are related. First, my add-ons won't uninstall. They all install correctly, but they won't uninstall. All of the ones I want to unnistall simply state "This addon will be uninstalled when Firefox is restarted." But, that message never goes away despite me restarting when I originally try to uninstall them. I still have the restart message on the addons dialog box, but when I press it Firefox restarts but the addons are still there with the above message.
The second issue is that Firefox takes FOREVER to open up (a couple minutes at least) and then proceeds to grow enormously on my RAM. I could definitely use some more memory, I'm not going to argue about that, but since the last big update (with plugin container I think, which I disabled) the browser has become a memory behemoth. Much more so than before. I don't even have that many addons, but wonder if the ones still there are affecting performance.
I tried a couple of techniques found in the help section, like deleting the addons manually (their files and folders) through the screen where you get a warning or something about changing Firefox. I'm not too tech-savvy so I don't remember all the exact names of stuff, but that didn't fix the problem.
I don't know if this is pertinent or not, but when I first got Firefox, several versions ago, I downloaded the addon FoxyTunes. I never ended up using it and thought I had uninstalled it but I don't think it ever fully left. It was still listed in my Add/Remove Program list (I had to go the registry to remove it) and occasionally I'll still see it pop up for a faction of a second in the lower right hand corner of the screen if the computer is hanging.
If it's possible I'd rather not have to do a complete uninstall/re-install of Firefox just because of the inconvenience of going through and re-downloading updates, addons, bookmarks, losing the most visited sites from my address bar, etc. When I first started using Firefox, it was extremely fast and reliable and that's what I'm trying to get it back to. At this point, my IE runs better which isn't saying much.
Any help would be greatly appreciated. Thanks in advance.
P.S. I have version 3.6.11, even though it says it's best guess is that I have 3.0.3

Give me and easy way to remove ADD ONS why should it be so difficult

We need to easily remove ADD_ON.
your instructions talk about a remove button that DOSE NOT EXIST.
I have downloaded the up dated Firefox 3 times today !!! BUT NO REMOVE BUTTON
when are you going to fix this problem!!!!!!!!

I looked at your screen shot, and it looks like all of you add-ons were
disabled. Did you do that? Try to right click on one add-on and see if
you get a menu. If nothing seems to work, there is a last resort. You can
reset Firefox to its factory settings. This will remove all add-ons and any
settings you have made. Bookmarks and history should not be lost.
==================================
The Reset Firefox feature can fix many issues by restoring Firefox to its factory default state while saving your essential information. <br>
'''Note''': ''This will cause you to lose any Extensions and some Preferences.''
*Open websites will not be saved in Firefox versions lower than 25.
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.

After I installed 4.0.1 I can't install add-ons. I have tried to reinstall firefox but it wont help. What is the problem?

'''My computer:'''
'Mac OS X'
Version 10.5.8
Processor: 2,53 GHz Intel Core Duo
Memory: 4 GB 1067 MHz DDR3
When I try to install an add-on, the installation bar won't move, and I can't remove/delete the progress too.

Yep, Firefox see's that website as being a forgery. Chrome and Firefox use the same database for phishing and web forgeries - they jointly developed that system.

How can I integrate add-ons into a PDF (Use Adobe Acrobat (in Firefox), such as Babylon English Dictionary?

How can I integrate the Fox add-ons into a PDF (Use Adobe Acrobat (in Firefox), such as Babylon English Dictionary? Many PDF do support my add-ons. BTW, the PDF in question is one that I have uploaded to my web site.

Babylon would need to support Adobe Acrobat for that to happen.

I can't remove add-ons in Thunderbird 24.5.0.
