Hmm, mine shows "25", which is a surprising amount.

We can get more information on the Troubleshooting Information page. Either:

• "3-bar" menu button > "?" button > Troubleshooting Information
• (menu bar) Help > Troubleshooting Information
• type or paste about:support in the address bar and press Enter

If you scroll down past the first one or two sections, you'll find these tables:

• Firefox Features - these are hidden extensions that Firefox uses for certain features (as the name implies). I have eight of these, and I assume they all count toward the total extensions on the Health Report.

• Extensions - this list should match the Extensions list on the Add-ons page. The ones that have "true" in the Enabled column count toward the total extensions on the Health Report. (I have 18 of these. Which is why a total of 25 instead of 26 is strange. Hmmm...)

Does that make (more) sense?

helllo

i have found troubleshooting page ..it automaticly adds "about:support" .it doesnt show any extensions..

Thanks for checking that. Those "Firefox Features" are implemented using extensions, so that is where "8" is coming from.

somehow i dont believe that ...couse i know others have different number of extensions installed

If you have used a profile for a very long time then you may have accumulate a lot of these special system extensions. You can find these in the features folder in the Firefox profile folder. You can cleanup this folder to make Firefox re-download extensions for your current Firefox version.

You can use the button on the "Help -> Troubleshooting Information" (about:support) page to go to the current Firefox profile folder or use the about:profiles page.

• Help -> Troubleshooting Information -> Profile Directory:
  Windows: Show Folder; Linux: Open Directory; Mac: Show in Finder
• http://kb.mozillazine.org/Profile_folder_-_Firefox

hello yes about:support takes me to about:profiles and by opening "root directory" i found folder "extensions" and its empty ..health still shows 8 extensions

thnx all for help ..i hope we will soon find solution :)

The Mozilla extensions now seem to be in the program folder:

32-bit Firefox on 64-bit Windows: C:\Program Files (x86)\Mozilla Firefox\browser\features

64-bit Firefox on 64-bit Windows: C:\Program Files\Mozilla Firefox\browser\features

The 8 .xpi files here match up with the "Features" section of the Troubleshooting Information page. As I said before, I suspect the Health Report is counting these Mozilla extensions in its total extensions count.

thank you

i checked it out and numbers are ok :) there was also extension folder in same directory as browser dir with one extension inside it..not user friendly name so i deleted it something like "23947823948798qweu009.xpi" ..thank you for all the help :)

Not need to worry about that file in the extensions folder.

• {972ce4c6-7e08-4474-a285-3208198ce6fd} default theme

This file is a placeholder for the builtin default theme, so deleting this file might cause problems. You can check this in about:addons appearance and ȟeck for errors in the Browser Console.

• "3-bar" menu button or Tools -> Web Developer
