Firebug 1.9b5 has been released (compatible with Firefox 5-12).
Firebug 1.9b5 fixes 11 issues.
A problem with HTML edit (issue 5058) is fixed in this release.
This should be the last Firebug 1.9 beta. In case there are no critical problems or blockers found, we’ll release Firebug 1.9 final in January.
Post feedback in the newsgroup, thanks!
