"Show release notes" fails in Add-ons Manager

Prior to manually updating extensions the "Show Release Notes" option fails with an error message. I always like to know what changes are going to be implemented before updating.
This has been occurring on every update of every extension for the last few months under FF28. FF29 has not fixed it.

I just tried a manual Addons -> Extensions update and got an update for [https://addons.mozilla.org/en-US/firefox/addon/adblock-plus/ Adblock Plus]. When I checked Recent Updates, The release notes were accessible (see attached).
<s>Maybe the release notes only show up AFTER an update?</s>EDIT: I just checked in another profile I had set to manually update addons. The release notes for Adblock Plus could also be viewed before installing the available update. Honestly, I've never even looked at that option in the Add-ons Manager
You didn't furnish the error message you saw and you didn't include any troubleshooting information showing your installed addons (see [[Use the Troubleshooting Information page to help fix Firefox issues]] for future reference). What you should probably do is visit the webpage for the add-on to see what updates are available.

Updating Flash Player Does Not Reflect In Add-Ons Manager or Plug-In Check

The add-ons Manager shows I have Flashplayer version 11.3.300.265. The Plug-ins Check shows there is an update, and I downloaded and installed Flash Player version 11.3.300.268. Six times! Each time, the installation shows as successful on the Adobe site, but FF14 does not reflect the new version, and the Plug-in check continues to insist that the version is out of date.
I had no problems whatsoever updating to the latest Flashplayer version in IE (8). But FF is once again giving me trouble with this.
In addition, the add-ons manager shows a version of Flash 9.0.45.0, last updated Feb 20, 2007. There's a big red warning that it's out of date. This is in addition to Shockwave Flash (the correct one) and Shockwave for Director (which is current). It's been like this for awhile, and I disabled the antique version of Flash and it does not affect FF or Flashplayer performance.
I tried deleting my plug-ins database, but I just get all the same info when it is rebuilt. Any suggestions or solutions would be appreciated.

Such old version are usually located in the plugins folder in the Firefox program folder (C:\Program Files\Mozilla Firefox\).
You can enable the plugin and verify the path on the about:plugins page.
You can set the plugin.expose_full_path pref to true on the about:config page to see the full path of plugins on the about:plugins page.
*http://kb.mozillazine.org/Issues_related_to_plugins#Identifying_installed_plugins
*http://kb.mozillazine.org/about:plugins
*http://kb.mozillazine.org/about:config
It is best not to leave that pref set to true as it exposes that full path to web servers, so reset that pref to false after you are done with the about:plugins page.

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.

This can be a problem with the file(s) that store the extensions registry.
Delete the files extensions.* (extensions.sqlite, extensions.rdf, extensions.cache, extensions.ini) 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 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 an update.

Why does add-ons Manager create a new tab every time I go to home page?

When I start Firefox my home page tab shows up along with an add-ons Manager tab and a plus sign for new tab. Every time I go to a web site and then return to my home page ANOTHER add-ons Manager tab shows up. This apparently will go on forever. I have had as many as 20 add-ons Manager tabs showing. The only way to eliminate them is to stop Firefox and then restart. Then it starts all over again. What is causing this?
I'm running the latest version of Firefox and Windows 8.1 on a Dell Inspiron with 8G's of memory and a 1T hard drive.
Please help.

Can you post back here a screenshot from this issue?

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.

Extensions will not show in add-ons manager; Firefox start-up Java error

When I click Tools --> Add-ons, the Add-ons Manager opens but no Extensions show in the Extensions tab.
I think the problem is related to a start-up error message I receive. Every time I open Firefox, an error message labeled "[JavaScript Application]" opens and displays the following:

The error means that an add-on called yoono is having problems communicating with a component made by Microsoft. I spoke to somebody with experience in working with the firefox coding, and he said that they're likely to be different issued and to see if yoono or another extension is causing the problems by opening firefox in safe mode. To open firefox in safe mode, [[Safe Mode|click here]]. If you can get to the addon manager there, I recommend you get rid of yoono

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:

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).

Firefox 10 Add-Ons Manager does not open in a tab

In later versions of Firefox 9 and now Firefox 10, the "Add-Ons Manager" refuses to open in a tab. Instead, it opens as a window with no border that will not move and cannot be moved or closed except by closing it from the Start Bar at the bottom of the screen.
This occurs on 2 separate PCs, one running Vista, one running XP.
I know it should open as a Tab, but I see no way to do this.
Do I need to change some setting to get it to open properly?
Thanks,
Ken West

updates 9 and 10 have caused me problems as well with add ons and the extra tab appearing welcoming me to firefox.
With update 10 all my add ons disappeared.. upon going to tools /add ons I found half my add ons were incompatable and the others were closed! I just opened them again and all was fine. Luckily the add ons I use often were still compatable.
The other option is to just add them again if they are compatible.. if not you can get around it by googling and comming up with a solution there somewhere.. One I use a lot is download helper and I had to do this about 3 versions ago to get it running.
There could be a solution in Help/trouble shooting and looking at extensions.. your add ons should be listed there and all be True..
If not you will most probably have to open Containing folder in top block and do something there.. Not sure what but will leave it up to the experts..
Seriously it would most probably be quicker to reinstal you add ons.

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.

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.

After Firefox 6 upgrade, Add-ons Manager does not load, it just says "loading" forever

After loading a toolbar and finding it to be not what I thought, I attempt to go to Tools Add-ons so as to "uninstall" it, but get a tab labeled "Add-ons Manager" that says "Loading..." forever -- what's up with that?

Firefox 6.0.2. Loaded something called "Productivity 3.1 Community Toolbar", version 3.7.0.6, "Toolbar powered by Conduit". Simply want to go to the Add-ons Manager and get rid of it, but don't seem to be able to reach the Add-ons Manager. Is there some other way to rid myself of this toolbar?

No one here is going to do anything about it. Send feedback to Apple.

Is Shockwave Flash 16.0.0.305 which is shown in the list of plugins in Add-ons Manager insecure

Following a reply from Phillip to my earlier question and having followed the links supplied ie installed Flashplayer from the Adobe website I am still unsure if I have the more secure version of the software, since in Add-ons Manager it just shows Shockwave Flash 16.0.0.305 which does not tell me what I need to know. More hslp would be appreciated. Thanks

How do I stop Firefox from launching Add-ons manager?

I do not like having extra tabs open and add ons manager keeps opening automatically. How can I stop this?

Firefox 8 i am on and its doing the same,very annoying,ill be going back to previous version...
do you guys at Firefox ever check your update's on any of your own computers before you release them?
might be a good idea,its the same with kylo,updates come screw everything up when they were working fine...im am a house builder,if i built houses with this many errors i'd be bankrupt by now....
