I've just created a new Firefox profile and now Firebug works awesome, webs go fast again, nice!
Same situation for me. Running OS X10.8.3 and Firefox 21.0
I get lots of spinning beach balls when Firebug is activated on a page. I'm not doing anything special in particular outside of viewing a website with Firebug open. Doesn't seem to matter which tab is highlighted. Is there anything else I can give you to help debug the problem?
firefox 21 and firebug 1.11.3 = slow
firefox 21 and firebug 1.11.2 = slow
firefox 20 and firebug 1.11.3 = works as expected
Same for me. Win7 SP1 amd64. Firebug is the only one extension enabled.

Hi Honza & all,
I too have had this just occur. To recollect what I did: I updated Firebug to 1.11.3 about two days back, less.js (it mentions how long it takes to load the less CSS) jumped to about 2secs from 1.6secs previously.
About half an hour back, I updated Firefox to 21 & immediately after my firebug has slowed down to a crawl. The same less.js page is taking 45secs + to load. Am using Windows 7 Premium.
I am installing on Ubuntu 12.10 as well & will report back with results.

When press F12 to enable Firebug, Firefox will take 100% CPU utilization.
Downgrade to 1.11.2, the problem is gone.
