This release fixes some issues reported after releasing Firebug 1.7 (all our automated tests pass). Note that this is supposed to be the last maintenance release for 1.7 branch. See description of news in three betas prior this final (b1, b2, b3).
FWG is currently fully concentrating on Firebug 1.8 that should switch to beta phase in couple of weeks and final is expected at the end of June (around the same time when Firefox 5 is coming out).
Here is simple compatibility table:
Firebug 1.7 is for Firefox 3.6 – 4
Firebug 1.8 is for Firefox 4 – 5
(Firebug 1.9 is planned for Firefox 5-6)
Firebug 1.7 is also uploaded on AMO, but it can take some time to make it through caches…
Please post feedback in the newsgroup, thanks.
