Please, if you don't have a test case or the time to write detailed
instructions on how to reproduce your problem, then post to the newsgroup,
http://groups.google.com/group/firebug. We can only fix bugs that we can
reproduce exactly the way you see the problem.

What steps will reproduce the problem?
1.View webpage on HTML tab in Firebug using the inspection feature
2.Change external CSS file and save file 
(any change, aka: background-color:#ffffff; )
3.reload webpage
4.Firefox freezes and requires task manager to close  
(If I turn firebug off, firefox does not freeze)

What is the expected result? What do you see instead?
Web page should reload without freezing firefox even when firebug is active.  

Which version of Firebug? (more specific than latest please): 1.4.5
Which version of Firefox? 3.5.5
On what operating system? Windows XP


To be able to fix a bug we need a test case and detailed steps to reproduce
the problem. Please attach a small test case or public URL for one. No
matter how trivial you think a test case may be to create, we almost never
work on bugs without one.
Don't think the page matters as it has happened with all sites I've worked
