After installing add-ons from the add-ons menu, my Mozilla Firefox 19.0 browser doesn't display the toolbar associated with that add-on. Like, I downloaded 'cocoon' from the add-ons menu. Even after restarting firefox, the cocoon toolbar didn't appear. Similiar is the case with other add-ons. What should I do? Please help.

It is possible that there is a problem with the file(s) that store the extensions registry.

Delete the files extensions.* (e.g. extensions.sqlite, extensions.ini, extensions.cache) 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, 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 check if there is a compatibility update available.

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

You can also check for problems with the localstore.rdf file.
