I had this happen in CCleaner. In Tools Startup Firefox, extentions and plugins are listed twice and all were listed as enabled. They are not all enabled. I disabled the duplicates but then I lost one extention and had to reinstall it.CCleaner is not in sync with the actual settings in Firefox. It seems useless to use this part of CCleaner. Does anyone know why this happens or if there is a fix?
This a on Gateway LT40 Windows 7 Starter.
there may be a problem with your JSON file that holds information about addons and extensions.
make sure that you're using ccleaner v4.10 which is the latest version
if you're not using this version, update ccleaner and report back here if the problem solve or not
It's v4.10.4570
What and where is a JSON file and what would I do to it to fix this problem?
http://www.fileinfo.com/extension/json
Your computer search engine should easily find the json files.
Since System Restore will reinstall a previous FF version, see if it will fix this issue.
I can't use system restore, it says "Windows has detected file system corruption You must check the disk for errors before it can be restored." I have run disk check and still have the error mesage. That is another thing I am searching for a solution. I found json files for addons and extentions but I haven't tried anything with them, they are dated 02/20/2014. I have a Firefox backup but it is from December 26 so I guess I would loose a few bookmarks but nothing too important If that is the problem.

Try a computer reboot in Safe Mode and repair the system. http://www.computerhope.com/issues/chsafe.htm
May require several Safe Mode reboots.
If holding down F8 doesn't work, continually tap it.
I can confirm the listing of things more than once in Firefox. I use Firefox Portable and CCleaner does list Microsoft DRM twice, showing both disabled exactly as I have the one disabled in Firefox Portable.

It looks like there may be columns past "program" are there?
Ok I've repaired C: drive but I don't think I need a System Restore. Firefox correctly lists active addons and extentions. CCleaner looks like the two screenshots I have attached. I guess I just don't need to refer to CCleaner I'll just look in Firefox Addons to see what is enabled.
Do you have multiple builds of firefox installed? I've seen this behavior with multiple builds of Chrome installed.
Also, do you have an extensions.json file in your profile folder? It's located in %AppData%\Mozilla\Firefox\Profiles\(profile identifier just click through)\ If you do, is there also an extensions.sqlite?
If so, try deleting extensions.sqlite
I don't think I have multiple builds of Firefox. How can I tell? I deleted extensions.sqlite there is no change. I have an extentions.json. Should I delete it too?
Copy it to the desktop first, so you have a backup. Make sure firefox is closed while you delete it.
I deleteted extentions.json Now only one of nine extensions enabled is listed in CCleaner Tools. It is not duplicated.
The active plugins listed are correct, but it lists each of them twice.
Now it lists all enabled extentions just one of them twice. All plugins are listed twice each.
How about this for a solution? Uninstall Comodo Ice Dragon. It is based on Firefox so that's why dual entries for extentions.
I suppose that'll do it, glad you got it sorted out.
