Bug Description
There seems to be something wrong with Firefox on my system, and I've seen it happening now for at least a couple of weeks on my Ubuntu Hardy laptop (even when the power is plugged in). This might be related to bug #131094 but I think it might be different.
Essentially, without warning, Firefox will stop being responsive, and I see from my System Monitor applet that I/O goes to 100% (but not really any significant CPU usage). I can still switch to other programs, only Firefox is unresponsive. It remains unresponsive for 15-30 seconds before eventually coming back to life. I have 4 GB of ram and plenty of spare disk space, and a fast current-model CPU.
I have the AdBlock Plus plug-in installed, plus the standard Ubuntu customisations.
Cheers

I checked the the AdBlock Plus developer and he hadn't heard of or seen this problem; he suggest that I could use Venkman to try to work out what Firefox was doing at this point, but didn't think I'd have much luck with that.
