Firefox crashes while using inspect tab pane in FireBug. Please follow the steps I describe:
1. go to my test page: www.domnodes.org/test.html 
2. activate fireBug (I use <F12> to activate)
3. click on the inspect tab pane
4. this is the first problem: firebug can not focus on a HTML element in the page.

5. Launch Firebug in a new window. This is an important step. Use the little red arrow button on the top left of Firebug
6. click again on the inspect tab pane.
7. Firefox crashes

It has something to do with the CSS on the test page. It is real simple common CSS declarations. There is also a second test page : www.domnodes.org/test1.html
This test page behave normal. No crash at all; There is only one CSS line difference.

See also my blog entry:
www.domnodes.org
