Couple of days ago I installed Firefox V-1.5 and Thunderbird for email. I've never been comfortable with IE or OE, both of which are magnets for virii of all kinds.
One click copies the necessary from IE and OE, no glitches, less than ten minutes to install both and have them run the first time.
I sometimes find that links don't work, but also know that enabling javascript would probably clear this up. Adaware not finding anything after several days of browsing also gives a bit of confidence, haen't been hijacked yet either. Some sites will have to allow popups, changing one to allow doesn't change all of them.
Otherwise a great improvement over IE, you can actually find tools where you would think they'd be instead of having to search 150 functions that you never use.
And it's freeware. I like free.
