After an hour or two of heavy use on the site I'm developing, Firebug develops the following problems:
Breakpoints get glitchy -- it becomes difficult to add/remove breakpoints. Sometimes I click on a line multiple times, see nothing, move to the console tab and back, and then see my breakpoints again.
Console stops logging xhr's, or stops logging debug statements.
Script files become non-viewable.
I'm working with a javascript file which is quite large (over 10k lines). I don't think this is a memory leak issue with my own code. I'm refreshing the page all the time. Looks like an issue on the Firebug side. Is my logic sound? Is there anything I can do to get firebug to behave better? Or do I just need to restart firefox every hour?
