My add-ons manager can't tell if plug-ins are up to date or let me update them.

I can't work with any of my plugins because the plugin check says the status of all my plugins is "unknown," and offers no action except the "?research" option. I can't uninstall them, either.
I am trying to make google hangouts work with firefox, and I think I need to be able to remove or update old google voice/video plugins to do that. But I can't get at them.

Does Google have any "uninstaller" or "updater" for its stuff?
If you don't mind deleting those plugin files by hand, you can get the locations from a different page. Type or paste '''about:plugins''' in the address bar and press Enter. For each plugin file, the physical location should be listed. Note that some folders may be hidden and in order to reach those, you may want to copy as much as possible of the path (not including the final file name) and paste that into Finder to drill down into the hidden folders.
Any luck?

HT2305 How can I tell if my downloads are up to date?

How can I tell if my downloads are up to date?

Hi..
Your downloads? Are you referring to your Mac OS X system software???
Click your Apple menu icon top left corner of your screen. From the drop down menu click Software Update ...

Plug-in page tells me all plug-ins are up to date, but I keep getting error messages from Firefox telling me they are not and are unstable

I keep getting error messages stating that my Adobe Flash is out of date and vulnerable. I go to the Add-ons Manager, click "update" and it takes me to the plug-in page which shows it's up to date!! Same with Java DT and Shockwave Flash. How can I update if I have the latest versions already!?! I am inclined to just allow the plug-ins to work but don't want my pc to become vulnerable. Please help!

hello Danagriz, unfortunately the plugin check page lags behind. adobe has released a critical patch for a vulnerability in its flash plugin, which is reportedly already exploited in the wild. therefore firefox will block insecure versions from running by default on websites for your protection.
https://helpx.adobe.com/security/products/flash-player/apsb14-27.html https://addons.mozilla.org/firefox/blocked/p794
please update to Adobe Flash Player version 16.0.0.235 as soon as possible, which you can download from http://www.adobe.com/products/flashplayer/distribution3.html (use the windows-exe for plugin-based browsers).
in order to update java, go to java.com (or if you don't need the plugin you can also uninstall it though the windows control panel)

How do I tell what Plug-Ins are installed on Safari?

The Settings > Safari menu on the iPhone has a switch to turn Plug-Ins on and off, but is no link on the menu to display which Plug-Ins are installed. Is there another way to view/manage Safari Plug-Ins on the iPhone?

Thanks for the confirmation. I tried browsing the local file that would normally display the plug-in information in the full desktop version of Safari, but the handheld version throws a message that it can't display local files.
It would be nice if there were information on line regarding what plug-ins are installed. I can see how they would want to keep tight control over installation and updates, but it would be nice to know what the unit will not work with. Lack of .swf support has already been discovered to be an issue.

In Firefox 5.0 I cannot view add-ons and can't tell if they're running.

When I click on Tools | Add-ons, Firefox just takes me to the Mozilla Web page for add-ons instead of showing me a list of the add-ons installed on this machine. I can't tell what add-ons are running and which are not. I re-installed Forecastfox, but I still can't see the Forecastfox information icons at the bottom of the browser screen. Adblock Plus is running, but now it has its own place in the Tools menu, separate from other add-ons.

Whew! Thanks. I wasn't expecting the information to be in the browser window. And now that I selected View Add-on Bar I can see the Forecastfox weather info. Thank you again.

How to stop add-ons manager tab from loading at start up of Firefox 3.6.17 (disabling the update add ons option doesn't stop it)?

Recently firefox has started loading the plugin checker in a new tab everytime it starts. This is annoying and turning off the automatic check for addon updates doesn't stop it.

It is possible that there is a problem with the files sessionstore.js and sessionstore.bak in the Firefox Profile Folder.
Delete the files sessionstore.js and sessionstore.bak in the Firefox Profile Folder.
* Help > Troubleshooting Information > Profile Directory: Open Containing Folder
* http://kb.mozillazine.org/Profile_folder_-_Firefox
* http://kb.mozillazine.org/sessionstore.js
If you see files sessionstore-##.js with a number in the left part of the name like sessionstore-1.js then delete those as well.<br />
Deleting sessionstore.js will cause App Tabs and Tab Groups to get lost, so you will have to create them again (make a note).

Firefox Check Your Plugins found "unknown plug-ins". My other plug-ins are up to date. To keep Firefox running safely and smoothly can the "unknowns" be safely uninstalled? How do I know if I need them? Where do they come from?

These are the Plug-ins in question;
Yahoo! activeX Plug-in Bridge Unknown plugin Research
Microsoft® DRM
DRM Netscape Network Object Unknown plugin Research
RealPlayer Version Plugin
12.0.1.666 Unknown plugin Research
RealPlayer(tm) HTML5VideoShim Plug-In (32-bit)
RealPlayer(tm) HTML5VideoShim Plug-In Unknown plugin Research
RealNetworks(tm) Chrome Background Extension Plug-In (32-bit)
RealNetworks(tm) RealPlayer Chrome Background Extension Plug-In Unknown plugin Research
RealJukebox NS Plugin
RealJukebox Netscape Plugin
I cannot say with certainty any plugins known or unknown installed on my computer are problematic. My other plugins are up to date. "Unresponsive Scripts" comes up quite often. No particular website, Grooveshark and Centurylink more than any others. Are the two (Plug-ins and Scripts) related?

option discovered in preferences. Really this and any feature that moves deletes or edits a users data should as far as possible be OFF BY DEFAULT. It shouldn't by default and without the users specific say do this dangerous and unnecessary thing without even letting the user know what it's doing!!! And then cause me a few hours (as i'm new to mac) searching for the option so as to switch it off. If i hadn't noticed the status cage declaring that it was copying files then i might never have twigged that this insane thing was occurring. And if i hadn't of noticed i would have been left maintaining the contents of the folder i copied the files to, the folder which as far as i was informed and so believed was also the location of the music files i was playing. How does Apple justify this 'genius' piece of software non-design? Surely it will hurt no one if this was off by default for new users - overall at least i dare say it would cause a lot less distress in the future for the unsuspecting public at large. Thanks for the support.

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?

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.

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.

I want to disable plugins, which i can do through add-ons manager, but every time i restart firefox they are enabled again

When i disable plugins firefox runs faster. I could uninstall the plugins, but i periodically want to use them. I have tried using click to play but i want some plugins to run automatically.
I want to disable selective plugins and have some enabled. When i do this via add-ons manager, all plugins are enable on restarting firefox.

i don't use any cleanup tools & MSE is my security software, which is rather unobtrusive and shouldn't interfere here...
i currently have one blocklisted plugin (see screenshot), but if i remember it correctly the problem was already present in my case before i had the outdated acrobat plugin installed.
sometimes when you enable/disable a plugin in the addons manager & press f5 afterwards, it immediately switches back to its old state/sometimes it will stay on the new state until a restart of the browser & in some cases it will remember the state even across sessions - it's just not working reliably in any way.
as far as i can observe the pluginreg.dat file in my profile folder the change of a plugin's state isn't written to the file as soon as it's toggled in the UI during a session, but only when the browser is getting closed - so the information has to be in the memory somewhere before and might be getting corrupted. i suspect it might be a general bug but i cannot reproduce it reliably .
''edit: forgot to attach the screenshot & i'm using the current aurora build''

Why can't I access extensions thru Add-ons Manager?

I just upgraded to version 8 on WinXP. Flagfox extension died on start up, so I tried to uninstall and re-install as suggested. However, Add-ons Manager says I have no Extensions, but Tools Menu lets me access and configure a number of extensions.

Well, after restarting Firefox enough times, everything seems to have gone back to normal. I even have extensions listed in the Add-ons Manager. I guess I have a successful upgrade to version 8, but it wasn't a pleasant experience.

Add-Ons Manager Tab won't go away

Using Firefox 10.0.2 on a brand-new Mac Mini running Lion 10.7.3.
Every time I open up Firefox, it opens in two side-by-side tabs. The one on the left is my home page; the one next to it says 'Add-Ons Manager' and it simply tells me the add-ons I've installed and so on. How do I get rid of this tab? I can click the X and it goes away, but it reappears every time I open Firefox again. I can't find anything in the settings that obviously gets rid of this for good.

Click on something below the Get Add-ons menu item on the left side of the Add-ons Manager tab.

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 <u>[[Safe Mode]]</u> 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.
* https://support.mozilla.com/kb/Safe+Mode
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.

My add-ons manager can't tell if plug-ins are up to date or let me update them.
