I don't have very high hopes for Firefox. They promised V8-like speed with 3.5, 3.6, and now they're promising it with 4.0, but they're still more than twice as slow, and have been every single time I have tried them.<p>The only reason I use Firefox anymore is Firebug. All of my normal browsing occurs in Chrome. Even if they eventually get Firefox's VMs as fast as V8 or SquirrelFish Extreme, the interface is clunky and old and much, much slower than Chrome, and really that's what makes it feel so much faster; Chrome starts immediately, I can move tabs quickly, there's no needless address bar/search bar segregation, and so on. I think I am a permanent Chrome user.<p>Firefox has had years to catch up to Chrome by this point and their results have been pretty bad, imo. Unless they can get it together, I think that Fx is destined to decline permanently soon.
