Firefox 4 is slow and uses a lot of memory with Adblock Plus

I have been using Firefox and Adblock Plus and I have been happy with it. Then I installed the Firefox 4 release candidate, and it was running slow and using lots of memory (usually almost 1 GB, sometimes more). After some experimentation, I noticed that it runs fine if I disable Adblock.

I got Firefox 4 on my Windows computer at work and it seems to run fine, even with Adblock Plus. AFAIK, the problem only happens in OS X.
