I was using Mozilla Firefox but it was not that much good as google chrome.
When I updated it, after that my facebook page was becoming non-responsive. Google Chrome is more secure than the firefox.
Browsing speed is not good to compare to other browsers. It does not have in-built adobe flash player plugin we have to download it externally. this just sucks. sometimes you tube videos not working well with Firefox.
Compare to chrome it has very fewer extensions. Compare to chrome it also takes too much of memory. Thats why sometimes your pc may slowdown. I recon chrome over Firefox.
