Firebug 1.8 beta 2 fixes 18 issues.
We are in beta phase and running full steam ahead to have final 1.8 release around the same time as Firefox 5 release (June 21).
Firebug 1.8 final targets: Firefox 4 and 5.
Do you want Firebug 1.8 to be the best? Help us and become a beta tester by installing beta 2. In any case, switching back to the release channel is as easy as clicking the Add to Firefox button on AMO.
Our automated testing framework has almost 200 tests that cover most of Firebug features, but still not every single one so, having feedback from you is always very valuable for us.
We are focusing on fixing bugs now and every report is having our attention. If you have any problems, file a new issue.
For developers: if you need Firebug Tracing Console for debugging Firebug itself install FBTrace 1.8b8.
You can also post feedback in the newsgroup, thanks!
