I have tried Chrome, Opera, Safari and other strange internet browsers .... Internet Explorer works ok but it takes up too many system resources...open up a load of tabs and the browser quickly comes to a crawl eating up system resources. Firefox on the other hand, I could have over 100 tabs or more and it still continues to function at 100% capacity. I always browse with Firefox but for some sites, I use Internet Explorer. Today you need to browse the NET with two guns; Mozilla Firefox is your AK47 while Internet Explorer is your 5mm pistol.
By the way, Google Chrome is infact very fast and user friendly but that browser has so many bugs I could not stomach it after a month of use. Chrome uses gears for plugins and almost has the potential to over-take Firefox if Google can polish it better but, the competition is hard specially since Mozilla has a tremendous reputation and it is open source which demonstrates the better of the internet community, people uniting together the make the lives of other more reliable, Firefox is perfect example of that.
I don't believe any browser will ever over take Firefox! Firefox is FREE and it works with no B.S, plain and simple. While the rest of the browser just seek to take money out of your pockets. Opera is not free, Internet Explorer is not free, you purchase part of it when you purchase your operating system....Chrome? That's just Google trying to over take the competition so they can get more users and earn more from advertising, can't blame them, we all need money.
