UPDATE 2008-03-20: This bug is easily resolved by upgrading to the latest Beta version of Firebug (currently 1.1). Thanks to PatternHead!
I’ve experienced this bug for quite a while now, and it is really annoying. Basically you can’t inspect an anchor in Firebug, and there’s no way around it.
Today I had enough and decided to do a thorough search on the web to get rid of the problem.. Looks like it’s a well known bug. Someone suggested that I’d revert back to Firefox 2.0.0.11, as it didn’t have this bug. I found an old version, sadly a .exe though. I could not find any mac equivalent, until I stumbled across a Ukrainian .dmg file… So now my Firefox is in crazy Ukranian, but at least it works properly!
Thanks! That worked like a charm… So obvious, I should've tried it from the start.
