Every single extension on the Add-on Manager is gone! Adblock Plus too! Also evertime is restart Firefox why is AdBlock Plus not up there with Greasemonkey?

I think the Add-On Manager is bugged! Adblock Plus disappears when Firefox is restarted as well. I'm using the newest version of Firefox too. This thing has more bugs than the old one.

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 check if there is a compatibility update available.
If this hasn't helped then also try to delete the addons.sqlite file.

Why does nothing appear when I select 'extensions' in the Add-on Manager?

Somehow, an extension/app called Coupon Saver (that I never wanted and which is truly annoying) has been installed. I uninstalled it on my laptop, but it needs to also be removed from FireFox. However, whenever I go to the 'Extensions' panel in the Add-on Manager, nothing comes up at all. It shows all the tabs on the right with 'Extensions' highlighted but beside it is nothing but a light blue screen. Why is this, and how do I fix it so I can removed the offending addition form my browser? Thank you for your time.

The Add-ons Manager will not display!

I've been having an intermittent problem with certain features not displaying at all. First it was that I could not "Customize" my toolbar for quite a while. It finally returned suddenly, in FF v4.01, after being unavailable since v3.5.
I've also been without the Magnifying Glass search icon since v3.5, which is still missing. And the show "Properties" option has also disappeared from the Right-Click Context menu, I don't remember if it started in FF v3.x , but I think it was right after upgrading to v4, and it hasn't returned since either.
Now it's the Add-ons Manager that has quit working. It has happened a few times before, but quitting and restarting Firefox brought it back.
This time, however, it seems to be completely disabled. I had just removed the IE Tab Plus extension, to be sure I hadn't installed it over the original IE Tab, which they said could cause unpredictable issues.
Next I used "Install Extensions" from the File menu of the Add-ons Manager tab, and selected a copy of IE Tab Plus I had saved to disk last October 2010 to re-install it. But nothing seemed to happen. No pop-up, or any indication/notification that an extension was about to be installed - nothing.
So I did a search for IE Tab Plus to acquire the latest version from it's Mozilla Add-ons page, where I noticed a "Comment" claiming the IE Tab Plus author was using it to secretly install Ad-ware, and recommended using IE Tab 2 instead.
I decided to do as suggested, but there is no link on the page to install IE Tab 2 from either. I decided to quit and reload Firefox, yet even in Safe Mode, I still can not get the Add-ons Manager Tab to load.
Note:
I also have Mr. Tech's cool Toolkit extension, which I believe added the "Extension Options" item to the Tools menu, and it is also empty now. It was not empty just before this. In fact it still displayed my extensions list after the Add-ons Manager had already failed to load again at all.

Start Firefox in [[Safe Mode]] to check if one of the extensions is causing the problem (switch to the DEFAULT theme: Firefox (Tools) > Add-ons > Appearance/Themes).
* Don't make any changes on the Safe mode start window.

Any way to add a URL variable to EVERY SINGLE url in the site, all at once?

Hi,
I'm managing a web application, and we're looking at changing from using cookies, to passing session variables in every HTTP request to maintain session information.
So basically, I have a variable that needs to be appended to every single URL in the entire site - not just in links, but in cflocation tags etc.
Is there any way to just ADD information to the end of every URL, without otherwise CHANGING anything in that URL?
This site is hand-coded, but I have access to Dreamweaver CS3, so I thought I'd ask if it was possible - it'd save me a bunch of time!
Thanks,
Joe

Hi, thanks for the reply.
I am familiar with DW's basic find/replace functions, but I don't think it'll work in this case.
See, the URL's are almost ALL unique. Many of them already include other URL variables... This is a pretty server-intensive web application, with a lot of data manipulation and database reads/writes.
So I was hoping for a function that could find all URL's (it could just look for a string containing .cfm), and append the code to include one more variable to the URL.
I see there's a way to use a regex in the find/replace tool, but it'd probably take me as long to write and debug the regex as it'd take to manually mod the URLs lol.
Thanks for any ideas!

It depends on how unique each URL is but you could try the Find and Replace function.
Highlight code in code view
Right Click
Choose "Find and Replace
You can then write the replace code and target a page or entire directory or site.

After automaticly updated to the version 7 the extensions page in the Add-ons Manager went blank and give this sentence "you don't have any add-ons of this type installed" but all the add-ons still working in the program

All the add-ons I had installed for the version 3+++ still working at the version 7, but the problem is that the extensions page in the add-ons manager is blank except a sentence that says "You don't have any add-ons of this type installed"

https://support.mozilla.com/en-US/questions/826729 has a solution for the problem

After updating Firefox to 5.0.1 the add-ons Manager did not show any of my add-ons, although they were all running.

After updating Firefox to 5.0.1 the add-ons Manager did not show any of my add-ons, although they were all running. Several restarts of Firefox, even with the add-ons disabled did not bring them back. I then installed another add-on and after restarting, all of the previous add-ons are now shown in the manager.
Running on Mac 10.5.8. Add-ons installed:
Adblock Plus, Add-on Compatibility reporter, Ant Video Downloader, Forecastfox, Google toolbar, Reload Every, Session Manager, and Steep and Cheap Watcher.
Note: the troubleshooting information was taken after the problem was fixed. Prior to fixing the issue, there were no items under the Extensions heading. Add-on Compatibility Reporter was the add-on that was added to restore all of the other add-ons, even though it was already installed.

'''Good to know you solved your own problem by simply installing another extension''', I like solutions that aren't going to cause extra work, or loss of data.
Here is what people normally have to do for missing extensions, as if not installed.-- https://support.mozilla.com/questions/826729
:http://kb.mozillazine.org/Unable_to_install_themes_or_extensions_%28Firefox%29
FWIW, renaming or deleting extensions.sqlite and the other files beginning with "extensions." causes the files to be rebuilt from the extensions directory, so nothing is lost, but they will be restored in alphabetical order.
I've solved places.sqlite problems by simply restoring a bookmarks backup, or creating a bookmarks backup and restoring that rather than face loss of history.
Please mark as solved so others will see your answer when looking for solved problems as solutions to there own or other people's problems.

Can I hide or lock (with password) access to the add-on manager?

So users can't see what add-ons I have running? I don't want my (tech savvy) children knowing or being able to alter add-ons monitoring what they are viewing. I've caught my daughter looking at inappropriate stuff and she's a sneaky one so she tries to hide it.
I'd like to be able to restrict access to the add-on manager (through the menu bar as well) or hide it completely so only I can find it.
Is that possible?

Note that some extensions can be installed globally in the Firefox program folder and won't show on the about:addons page.

How to hide (not disable) one or multiple extension(s) in Add-ons Manager?

I have installed Play Music 1.6 on my computer. However, this extension shows up in the Add-ons Manager of my computer. I don't want anyone to be able to see the description nor disable this extension. My nephews use my computer frequently and I want to make sure they are not going to inappropriate websites.

Note that you still see the extension on the "Help > Troubleshooting Information" page and that starting in Safe mode will disable it like all other extensions (i.e. starting with Shift pressed is sufficient).

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 hangs when clicking "Options" on any add-on in the add-on manager.

After the latest update the add-on manager window hangs whenever i click on the options for any add-on. The main firefox window works fine, but i am unable to to go into the options for my add-ons. Moreover, my search engines keep rearranging and disappearing. I dont know if that's relevant, but I thought I should add it too.

I installed 4 different extensions ... when I click on addon manager and click any extension "options" the whole addon manger freezes up for me as well. I can't close or escape the window. I can open another browser window but the old window with the addon manager is frozen so I must use task manager to close.
After trying many options this worked for me ... I uninstalled Adobe Flash plugin and reinstalled Shockwave Flash 11.0.1.152 ... I do not know why or how but it fixed the problem Now everything is working HURRAY!

What happened to the add-on manager?

I no longer have an add-ons manager. Clicking on tools and add-ons sends me to the get add-ons page instead. What happened to the add-ons manager? How am I supposed to disable or customize or uninstall add-ons?

Don't you see the about:addons page with the menu column at the left to switch to the extension page?

Why does the Add-ons manager take an excessive time to load and can I view my add-ons without going to the add-ons manager?

When I start my browser up my everything that I have been working on comes up without any problem and I can open a new tab to go to another site without a problem, but when I go to the Add-ons Manager it can take over 3 minutes to load and that's if I don't stop it. My other question is can I view my add-ons, plugins, etc without having to open the Add-ons Manager?

Check out this similar thread: [https://support.mozilla.com/en-US/questions/836711 Some websites, Mozilla included, appear to think I'm using a different version of Firefox from the one I am using; how can I fix this? | Firefox Support Forum]. Does that help?

The Add-Ons Manager is supposed to auto update your add-ons but it is not detecting the latest version of Adobe flash player. Why is it not detecting the update?

I have Adobe flash player version 10.2.152.32 installed and Adobe has released version 10.2.3.1 so why is the add-ons manager not detecting that an update is available?

Adobe Flash is not an add-on, it's a plug-in and you have to use the Plug-in Check to check for updates:

Firefox crashes when I navigate pages on grooveshark, try to open the add-on manager, and when I visit any number of random web pages. What is wrong with it?

Firefox never crashes immediately on startup or when I close the windows, but it crashes usually soon afterwards. It always crashes shortly after I open the add-on manager, so I can't even see which plugins I have that might be causing problems.
