Actually, I've been fairly satisfied with the unstable release of the
Google Chrome for Linux (.deb file for 32-bit systems) browser. I use it as my secondary. The pros and cons with it, for me, are:
PROS:
Set-up is easy, and imported all my /.mozilla data with one click and no errors.
Loads pages very fast.
Uses, on my system anyway, maybe a fourth the resources that Firefox uses.
By the same token, this allows you to keep your browser open while running resource-heavy apps.
CONS:
Has few extensions. If, like me, you have five or more extensions running on your browser, you'll have to make workarounds. Which, to be fair, could also be seen as a pro, if you're the type that likes to make workarounds.
It does have an ad-blocking feature, but it's Privoxy, which a lot of users might find unwieldy compared to the ease of Right-click>AdBlock Image.
I do use it as a secondary browser, for the occasions when I want a browser open while doing something resource-heavy like playing Fallout 3 in WINE, for example. Plus, they seem to be updating it on a weekly basis, so they are actively developing it, too. I recommend it. With time, it could become a primary browser, but I don't think it's quite there yet.
