There are tens of thousands of compatible add-ons (BTW, the most recent version is 31, not 30) so we can't give you a list. If there is an issue you are having with a specific add-on we can give that to you.

Go to the Mozilla Add-ons Web Page {web link} (There’s a lot of good stuff here) and search for what you want.

You can look up what you want, and the site will tell you if it is not compatible to your current system.

Also, if one of your add-ons is no longer compatible, the manager will tell you.
