Not really. Use Chrome or Safari? I still use Firefox predominantly but find myself using Chrome more and more often since 4. I find it hangs a lot also, more than 3.6.x. It also uses gobs of RAM, it hovers at around 1GB of "RealMem" (or RSIZE). Idle CPU regularly around 15% sometimes 25%. Whereas on Fedora 14/15b Firefox 4 loading the same web sites, on the same hardware, is using at most 200MB. Usually it hovers around 150MB and doesn't go much higher. And it draws a lot faster. And the idle usage is 1% or less. I don't understand why. Maybe Linux is putting the application data caching into its separate "cache" category, whereas on Mac OS X the application itself appears to take the memory hit for everything that's cached. But that doesn't explain the lack of hanging, lower CPU at idle, and overall much faster performance. And I don't think FF4 on Linux has the ability to use the GPU for acceleration like it should on Mac OS, because there aren't proprietary drivers yet available for Linux on this same hardware. Javascript execution feels much faster in FF than either Chrome or Safari on Mac OS, and that makes it worthwhile for me.
