With my experiences with firefox i found that it is much easier to view than microsoft internet explorer...not only do you get tab browsing but the perimeters for printing is much much better...with internet explorer the words run off the page....
I don't like how much resources it can eat up, especially with extensions installed due to crappy extension development. I do like it and use it a lot, I wish the linux version was as robust as the windows version.
Firefox is better compared to IE because it is opensource. You can get various features to suit your surfing needs. Maybe if IE shows its codes and let users make add-ons to it, it might get back into the race to be the best browser.
I like mozilla firefox a lot better than IE. you can have tabs instead of opening 20 windows of IE that fills up ur taskbar or whatever its called at the bottom of your screen
