It has great plugins as well. I use a user agent switched for sites that employ 'internet explorer only' features. Also video downloader for youtube etc.
Greasemonkey is good as well for filtering out trolls, o2 thieves etc.
I switched. Never looked back ... bu66er Bill Gates and his Planet Takeover.
Firefox will import IE favourites for you.
Loads of bolt-on goodies ... if you feel you really need them.
And the esenttial spoll chekcer ...
Note that not ALL sites are happy working with FF ... but I can't remember any recently, apart from that one I had to close down quickly when Management came home early ...
There are several other browsers available that will make you give up IE forever. I am not an IT type but I do create some webpages for my office so I keep about 6 browsers on my desktop at work in order to check to see if the webpages I create work OK with all the browsers.
My favourite browser is Opera, available at Opera.com. When you install it will put all of your IE (and firefox) bookmarks into it's bookmark list. Opera's tabs work very well if you want to hop back and forth between several pages. Decent language support is available. The only problem with Opera is a few archaic pages optimised for IE don't work well.
Firefox is great also. Decent tab system, also ingests bookmarks from IE, fast. Firefox has an edge in languages and if you would prefer that your browser be in Irish Gaelic, Welsh, Basque or Frisian; Firefox would be your choice (at the download site there is a list of about fifty (50!) languages).
Given that the downloads are free, if you have a decent hard drive why not download both and compare. Whatever you choose will be better that IE.
