Want to help your good friends at Mozilla do a little add-on testing?

It takes a lot of work to see if add-ons still work or not, so you can do your part by installing the Add-on Compatibility Reporter.  Help the Firefox team make sure your favorite add-ons get updated for upcoming Firefox releases with this tool. 

Here is a little more about the add-on from the Mozilla team:

After installing the Add-on Compatibility Reporter, your incompatible extensions will become enabled for you to test whether they still work with the version of Firefox or Thunderbird that you’re using. If you notice that one of your add-ons doesn’t seem to be working the same way it did in previous versions of the application, just open the Add-ons Manager and click Compatibility next to that add-on to send a report to Mozilla.

Also worth mentioning is that Mozilla only recommends this add-on for alpha and beta users only. So if you like to stay on the cutting edge, this add-on is for you. You can pick up the Add-on Compatibility Reporter on the Firefox Add-ons web site.
