I have installed Firefox 12, i then added 6 add-ons, when i go check on them, i go to "tools"\"add-ons", and find nothing there. Some show up under "tools" (like tweaktube and delicious) but none show up in the main list of add-ons.

الحل المُختار

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.
