Only google chrome, only hardcore 
Firefox only.
Firefox due to some add-ons that i`m addicted to 
Firefox for the habit plugins and a true Firebug for real dev that is what i use.
More …. Safari i will never use due to their dictatorship policy.
Chrome- is way to nerdy browser for my taste …not cool for my karma ..

Chrome all the way. Firefox is a memory hog, and is generally slower and buggier than chrome in my experience. Plus chrome has awesome built-in dev tools!
+1 I use Firefox for designing only (firebug). Other than that Chrome remains the best (so fast!)
I found this on another thread (posted by Enabled), it may be useful
:

EDIT : To people saying that they can’t leave Firefox because of add-ons, I never found an add-on on Firefox that I can’t find on Chrome. There are always alternatives.
Firefox for its add-ons.
Even though I can install most of them on Google Chrome, I just somehow dislike Google Chrome’s GUI . 
Is there any Google Chrome add-on to make its UI pretty much the same to Firefox’s? 
Firefox, especially for the add-ons ; I agree that it is really slow sometimes because of the memory issues , but I can’t help it , I use it for everyday browsing and debugging.

Crakken saidGive me a good alternative for FireBug and i’m switching today. Don’t even mention Chrome built in dev tools, because they don’t even come close to FireBug
There are always alternatives.

Same here. Also, don’t say Firebug Lite 
Chrome. Best browser out there in my opinion.
