Finding the bad Firefox plugin

I'm using firefox with a handfull of plugins, probably like everyone else. Now somehow, firefox locks up a few times a day, with CPU usage going up to 100% and staying there.

Now here's the question: Is there an easy way to find the plugin that causes the problem? I'm particularly looking for an easier way than to disable plugin after plugin and waiting to see what happens.

Is there some way I could attach a debugger (this being on a linux box), or detect what's going on "inside" in another way?

A little easier. Disable half the plugins. If symptoms continue then do the other half. Once you have shown which group has the problem, repeat by halving that group. This reduces n steps to log n.

But all these processes will fail if:

• It is the interaction between two (or more!) plugs.
• It is not an plugin (core FF issue, or maybe an extension, or some mixture across categories).

I've found (after googling for other search terms) the following page, which is quite helpful:

http://kb.mozillazine.org/Problematic_extensions

It lists some of the plugins that I'm using as problematic - Firebug, DownThemAll, Adblock Plus - with some good hints and workarounds for some of the problems.
