Hello, the Tools of 3-bar menu > Add-ons not working ?

If you click ctrl+shift+A works ?

also try if you write in location bar about:addons

thank you

Thanks, Ideato, but here's what I see if I do any of those three things you suggested (screenshot). Can you show me what I should expect to see?

After going there click on extension (below Get addons),here you can see all your addons you have installed.

Thank you, Chandan_Baba. That was very simple, but somehow not obvious :)

Note that you can also see this information on the troubleshooting information page.

To add to this the word Addons does not refer to Extensions only as it is a general term that also includes Plugins, Themes (both complete and lightweight) and search engines.

Plugins like Flash, Java are not actually installed in Firefox but are on system and Firefox has foiund and is making use of them.
