Firefox does not recognize that I already have add-ons installed (prompts to install add-ons I already have installed AND turned on). Why?
Add-ons, which are updated and already installed and running (and have been for some time), seem to think they are not added. When looking at my add-ons in the Tools menu, they are listed as enabled. However, clicking to go to their information page on the web (where you can read reviews, and where you originally chose to add them to Firefox), the "add to firefox" button is available. (As opposed to some sort of "already installed" or "uninstall" or "reinstall" button) I tested the button to see if pressing it would THEN tell me "you already have this", but it didn't! It started downloading the plug-in I already have! What is going on?

hello Amsuko, the "+ Add to Firefox" button on addons.mozilla.org and similar sites is just a normal static element on the website. websites don't have the possibility to query which extensions a user has already installed (this would probably be seen as a privacy/security breach). in case you install an addon that is already present on your system, it will simply get replaced...
