The Add-on Compatibility Reporter (ACR) has been redesigned and rewritten from the ground up to make it easier to use!
After installing the ACR, you can report if the Firefox add-ons that you're using are working properly. 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 'Report Issue' next to that add-on to send a report to Mozilla.
Three weeks after a Firefox version bump, we will be prompting users using Aurora/Beta for information about whether their add-ons work. This will be a popup panel. The panel can manually be initiated by clicking the add-on icon in the Add-ons Bar.
Even if your add-ons all work fine, if they're marked incompatible, please let us know that they work fine by submitting a success report so we can encourage the add-on developer to update their compatibility information.
We'll collect all of the reports and let add-on developers know what users are having problems with, or if their add-ons seem to work just fine in future versions of the product.
If you're an add-on developer trying to find reports submitted for your extension, head over to the Report Viewer here: https://addons.mozilla.org/compatibility/reporter
