Iv'e been using Firefox for last five Years,for the last two month Iv'e been using Chrome more and more until it became the default browser . Both of those browsers Firefox and Chrome are installed on my machine and don't get me wrong I have allot of respect for Firefox. Five years ago there was no real alternative for IE, at least on Windows Firefox was the only safe browser and Iv'e been using it since then and of course since I started using Ubuntu Iv'e used Firefox.
Lately something went bad at Mozilla, Firefox takes allot of time to start, the number of crashes is increasing and installing extensions became a big problem. In the meantime Chrome has started to gain more and more fans, It has almost the same extensions as Firefox and it's faster, so why not ?
In January 2009 Firefox passed IE and it's peek number of users was in July 2009 but since then the number of users is going down. Firefox is still the most common browser, but one can remember that once was IE. IE is still the fastest looser of users mainly to Chrome but also Firefox (check the numbers here).
Since I had to add something graphic or a picture I add a graph I mad on Google Docs (I like to test it once in a while, It's getting better, but that's not enough for me) . back to the graph, the graph is made to January - June 2010, IE includes IE 6, IE 7 and IE 8. You can see that IE is loosing very fast to Chrome but Firefox is also starting to loose, is starting to loose users, will Firefox end up like IE ?
