FF8 is out. FF10 is in beta testing.
I had to put FF5 back on my main XP machine, because FF7, which was supposed to correct part of the ongoing memory-hogging FF has become notorious for, didn’t. At one point, with only one window/tab open (and it blank), FF7 consumed over 400k of memory.
I did upgrade my Win7 laptop with FF7. The laptop has enough memory that memory consumption has not become a problem.
The big problem I find with the rapid release is trying to keep extensions/add-ons updated. I lost some that never made the FF upgrade beyond 3.6 series. I lost a couple of others that got shelved between FF5 and FF7.

FF needs to rethink their rapid release philosophy. It may be cute and fine for developers, but for productivity users, new releases are more trouble than they are worth.
400 MB, I guess.
I am running FF7 on a laptop with 256 MB total RAM. Works OK, for a few tabs although 192 wasn't enough and had to upgrade.
I used Firefox ever since it started but finally gave up on it 3 weeks ago because of the memory hogging issues. 2 years and still it eats memory like breakfast cereal.
I tried Chrome and it works so much faster and so little memory. Set up was easy and it imported my favorites.
