Upon first install of Firefox 4 beta 3 codenamed: “Minefield” you will notice right away that they have simply thrown away what Firefox was and totally reinvented it.
Firstly, the look, as you will see it looks similar to Google’s Chrome browser which is very simplistic but perfect as there is nothing to clutter your screen and allow you to browse without hiccups. Secondly, they have added a progress circle so you can see how far a webpage is loaded without going to the tab which I found very useful with more then 30 tabs open.
Firefox has yet, after their launch of the browser in 2004, to fix the memory leaks and stop the need for the browser to use over 1gb of ram at all times and stop constant crashing. There is sure to be many glitches and road bumps until the official release of the browser but so far it seems they have really stepped up their game and I would recommend it as a replacement to your current browser.
