Beta version yet always don't works on Linux Rated 5 out of 5 stars
The 1.2.0b4 version yet always don't works on Linux with Firefox 3.0.
Bugs on Linux (Debian Lenny): after Firebug install in "Devices" and right-click context menu cannot be found Firebug option and cannot Firebug icon. "Settings" option cannot be used in extensionlist.
Good news: Firebug works on Windows with a full functionality :)
I like Firebug and it is necessary for my work. I hope for it repaired will be on Linux too.
