Example addons that are currently working include no-script and downloadthemall. Both addons are working but do not show up under extensions. I can only see my plugins, such as java, realplayer, shockwave etc. It's very annoying when trying to acess my addons to constantly be taken to the "Get Addons" page.

Chosen solution

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 do a compatibility check or see if there is a compatibility update available.
