Firefox 9 Aurora was updated to Firefox 10 Aurora a few minutes ago. The update dialog listed several incompatible add-ons which I ignored at that time as I'm using the Mozilla Add-On Compatibility Reporter to make add-ons compatible. When I started Firefox 10 after the upgrade installation I noticed that the web browser listed all of my add-ons, with the exception of the Compatibility Reporter, as not compatible with Firefox 10.
Something was not working as expected, and so the search for a fix began. My first thought was that the Compatibility Reporter needed an updated, checked the official site and noticed that none was available there.
I then checked the add-on manager in the browser to see if I could re-enable the disabled add-ons. This too was unfortunately no possible.
Next step were the Firefox Options, I thought that Mozilla maybe had added a switch or flag to the options to prevent automatic add-on enabling. This too was not the case.
Last and final step was my decision to force compatibility directly in the about:config dialog, and this worked. But lets start at the very beginning. Enter about:config in the address bar and tap on the enter key. You see a big list of parameters. Enter compatibility at the top to filter for all parameters with compatibility in the name.
If you have the Add-on Compatibility Reporter installed you will see a large list of compatibility parameters. They start at Firefox 3.6 and go all the way up to Firefox 9. Yes, that is right. My take on this is that the parameters are added by the Compatibility Reporter, and that the program was configured to add compatibility up to Firefox 9. Considering that Aurora is now Firefox 10 and the Nightly builds Firefox 11, it is safe to assume that we will see an update of the program soon that remedies the situation. For now, you have to add the compatibility information manually. Right-click in the listing and select New > Boolean.
Enter extensions.checkCompatibility.10.0a as the name and select the value false on the next page. Restart the browser afterwards. If everything worked out correctly your add-ons should all be enabled again in the Firefox web browser.Advertisement
