I upgraded my Firefox to 25, from 24 I'm getting problem regarding installation of any add on. Every time I start Firefox it notify me to install the disabled plugin. I allow installation, and then restart FF, but it still stay opened and open a new tab for the same prompt. It's not just annoying, but it's not installing the add on into my FF.

I just want to DISABLE (by unchecking or sth.) the default feature into my FF. I'm a developer and aware enough what add on is running behind the scene and how to remove them.

Which plugin(s) is/are involved in this alert?

Just to be sure: do you mean extensions (Firefox/Tools > Add-ons > Extensions) or plugins (Firefox/Tools > Add-ons > Plugins) as those are different add-ons?

In case of extensions, you can check for problems with the file(s) that store the extensions registry.

Delete the extensions.* files (e.g. extensions.sqlite, extensions.ini) and compatibility.ini in the Firefox profile folder to reset the extensions registry.

New files will be created when required.

See "Corrupt extension files":

If you see disabled or not compatible extensions in "Firefox/Tools > Add-ons > Extensions" then click the Tools button at the left end side of the Search Bar to check if there is a compatibility update available.

If this hasn't helped then also delete the addons.sqlite file.
