I did more digging and testing. I fixed my performance problem but discovered something pretty strange and disturbing that might be relevant to other performance issues I've seen posted.
Way back when FB1.3 came out, I had a number of problems w/it (initial bugs that were later corrected) and one of the things I was told to do was try running it in a newly created profile. So I did that and it fixed some minor things, but had a major performance problem (the one I posted about above). Since then, I've tested all updates in either that new profile, or an even newer profile. In every case, the performance problem existed. But... I had never actually tried to completely uninstall Firebug on the new profile. So I did that today. And performance was still horrible even w/out Firebug. So it was the new profiles, and not Firebug that was the problem. Maybe. To test that theory, I backed up my original profile, then upgrade it from FB1.2 to FB1.4 and it's super fast So now I'm left to wonder why my default profile is so damn fast, while all newly created profiles are so damn slow. And some co- workers also have very slow performance which I now suspect has to do with their Firefox profile. Very strange. Makes me wonder if everyone installing Firefox these days is seeing greatly reduced performance due to some non-obvious (to me at least) change in the default profile settings. I mean, we're talking instantaneous site loading vs. 10 seconds for this web application I'm talking about. It's less noticeable on sites w/fewer resources to be loaded. The"connecting to..." message shows up on the status bar a lot and stays around a lot. So whatever the profile difference(s) are, they seem related to slowing up connection speed. Guess I'll try the Mozilla folks next.
