No doubt,Google chrome is the best and fast internet browser.But in terms of seo i would recommend Firefox.Because it provides so many add-ons features that makes every task easy.
My preference goes to either Chrome or Safari on OS X. There's something about Chrome's user interface that makes me want to continue using it even though Safari is already doing a good job as far as browsing goes.
Safari's user interface could work out for me with a little bit of modification as I have done here not too long ago, but so little can be done with the current resource files. I'm not too fond of extensions, usually 1Password and Adblock would do the trick and both browsers have these two so there's no problem there.
Firefox isn't an option as it can't even do something about the awful scrollbar integration. I just have it installed for the sake of testing sites for compatibility issues since there's a lot of people still using this browser to this day. Should I even mention that it renders fonts horribly? Most especially fonts from Typekit.
Finally, Opera shouldn't be much of a problem once it starts using the new Blink engine.
I use Chrome since Facepunch (http://www.facepunch.com) loads incredibly slow on Firefox for some reason. I also like the design of Chrome. Nice and tidy!
I mainly use Google Chrome on computers with more than 1GB of RAM, and running Windows OS, but Firefox, and Opera feel faster on slower computers with 512MB-1GB of RAM.
Firefox 20 is pretty fast on Linux, and Windows XP.
I still have a computer which runs Windows XP which only uses 512MB of RAM. I think a lot of computers from 2006 or older still have 512MB of RAM.
Linux computers which run a Linux distro like Lubuntu, Puppy Linux, and Tinycore Linux may also be using less than 1GB since having more RAM may not make their computer much faster since Linux runs faster on Windows on older computers with less RAM and slower CPUs.
I found a web browser called Slimboat which I downloaded from http://www.slimboat.com/en , and Slimboat is fast because it uses the Webkit web browser like Safari, Chrome, etc.
Slimboat is available for Windows, Linux, and Mac.
Voted Chrome and it is my favourite, though I recently learned that Firefox is more secure than Chrome, your passwords saved in Firefox are the most encrypted hence secure than in Google Chrome.
