It's a web browser. I use it, a lot of people are crazy about it. Some people think it's going to be the Internet Explorer killer, but I think Microsoft is too cunning to let that happen.
ohh thats it, well ill give it a look but im fine with internet explorer. ill see what kind of features they have and see if i like it, im not a big fan of change
The big thing people like about it is how customizable it is, there are literally thousands of extensions that do anything from display the weather to play music to an FTP client, not the mention all the different themes / skins for it.
firefox owns ie bad. even the outdated firefox can out browse ie7. firefox protects users from spyware, popups, viruses and is overall a faster browser. it is a bit more demanding of memory than ie but it is certainly worth it.
firefox is awesome. It's way better than IE. IE is just a haven for spyware and all sort of crap, it's also gotten bloated with version 7 IMO. I don't even use IE unless it's for updates.
