This. I tried Chrome two or three times for several months a few years ago. Yes, it was fast but had issues with loading pages I usually used, e.g. I click on a link and shows me white page for some time, long enough to be annoying. On the other hand FF since pre 1.x versions is always about the same. I don't see big improvements in speed and I don't see big degradation too. The only problem I had is with Atlassian web pages that tend to memory leak when left open for days. At home where I never open them FF is very stable.
