Oh, 3.0 beta 1 then (the first beta for Firefox 3.0)

I had the same experience. Using Firefox 3.0 beta 1 on Windows XP SP2. After several minutes of normal use, no matter what page I was on or how many tabs were open (from 1 to 20) Firefox started to consume more and more RAM (up to 400mb until I killed it). This happened even if I I did not touch the computer. Strangely I did not experience that with nighties or alpha8. I did not test using Safe Mode...

Does it stop happening if you go 
  Edit > Preferences > Security > Uncheck "Tell me if the site I'm visiting is a suspected forgery"

If so, this is a dupe of bug 404645.

Sorry, I uninstalled previous ff3 beta1 and create a clean install, now the problem is gone so I can not replicate it. If it happen again I will try to run ff in safe mode and with unchecked option you mentioned. I do not exclude my leak was caused by some extensions like print to pdf or ctrl+tab, adblock plus seems to work fine with beta1.

This probably was bug 404645, which Google fixed by changing the data served for the safe-browsing feature. Can't prove that though, so --> WORKSFORME.
