Wait -- if there are extensions you can't live without and that have no javascript alternative.
Chrome isn't released for Linux yet (although there is a developer preview, this only works on Debian/Ubuntu-based distros -- it definitely doesn't work on the RedHat-based distros for 64-bit machines yet).
Chrome is only just getting going with add-ons and such, so if there are add-ons/extensions that you can't live without (other than adblock plus which can be replaced with a Privoxy proxy, or using one of the many javascript greasemonkey-ish scripts which can also be enabled in Chrome.
Personally, I find that general browsing is so much faster in Chrome that I use it and put up with the lack of extensions, and use Firefox for just the very few things I really need it for (debugging web apps with Firebug being one).
