Even FF7's UI lags a little with 10+ tabs open on my sig rig. The close tab animation goes at around 2 fps, which is annoying when you're trying to close a bunch of tabs at once.
Oh and when I was trying to get my memory usage over 1GB in Arch Linux, I had to open 46 different tabs in Chrome, then switch over to Firefox and open another 8 tabs, because adding more tabs in Chrome wasn't really getting me anywhere.
browser.cache.disk.enable = false
Sorry but FF doesn't touch the swapfile on any of my OSX, Windows or Linux systems. Chrome has a cleaner UI by default(although you can change the FF UI unlike in Chrome) but it's nowhere near as fast as FF8. With Fasterfox+Speed DNS it just makes the difference even more drastic. I just tested 93 tabs with memory never going above 1.46GB. I could never do that in Chrome, much less, trust Chrome to not lose those tabs during a crash either. Chrome's profile gets corrupted way too easily and I've lost so many tabs with it.
There is no lag at all moving tabs around or closing/opening them for me. Enable hardware acceleration and if that doesn't help, reset your preferences or make a new profile.

Mozilla need to fix this, it never happened in 3.6.18 or 4.0/4.0.1
You need to try FF7 or FF8. Memory defragmentation has been fixed.Edited by PoopaScoopa - 8/9/11 at 4:46am
