[d] enclosed in brackets chaotic perfectionist for hire

As I mentioned a few days ago, Firefox has been crashing on me a lot in the past couple of weeks. Every time it happens, I get a little more upset, since I just want it to work (who doesn't?).

To be honest, I probably have too many Add-Ons installed. At one point, I think I had almost 40. Before anyone says anything, I actually use most of them on a daily basis. Here's what I have, including the versions, but not the Themes (thanks go to Listzilla for generating the list):

Not all of them are enabled right now, but they're all in there. I think the problem has been Firebug, which I use to figure out how pages work and what is (or isn't) working on pages. It's super useful, and I wish I didn't need to disable it, but it's necessary for now. I also want to re-enable NoScript, which I've had mixed success with in the past...

This isn't one of those "list of great extensions" things, just a little something to show what's happening on my particular browser.

Are there any good Firefox extension debugging tips out there? I'd like to know what's actually happening when it crashes, so I might be able to narrow down where my problem is.
