I’ve been using Mozilla’s browser (i.e. Firefox) for a long time; its tabbed windows features is convenient, it blocks popup windows, and it has never crashed on me.
However, Firefox’s latest version has been running slow on my system, taking a long time to download pages; so I decided to try, an Internet Explorer-based browser that has the same features as Firefox and it’s free. I’ve been using it for a few weeks with no complaints.
I’ll go back to using Firefox once they produce a release that doesn’t bog down my system.
