definitely chrome. i've tried many different browsers, but chrome is the best. it's fast and has plenty of extensions. ghostery blocks google trackers, so no need for chromium!
I've used many browsers in the past, including Netscape, Firefox 0.x, IE5, Opera, and others. Firefox has always been my choice browser, as Mozilla stands for a free Web and is committed to your security. Since installing Windows 8 x64, however, I've been using the 64 bit version of Pale Moon and love it! PM is based on Firefox, but there is a noticeable improvement on speed and responsiveness.
Tried many browsers over the years, but for me it's Chrome all the way. Firefox - Has some interesting UI features planned but feels like a bloated hog so can't commit to using it. IE - From v9 onwards it's good but compared to other browsers it always seem like it's missing something. Opera - Used older versions a handful of times, it always seemed cluttered, v15 (Beta) is pretty much Chrome in disguise so I've been using the beta for about 3 weeks, shaping up to be a good browser.
