I downloaded the 272MB version and I've installed it on 5 computers of varying types with no problems whatsoever.
The firewall is easy to disable if you don't need it and the pop-up blocker in IE means I don't need Google's toolbar anymore.
I had been using Mozilla Firefox but I didn't like some of the bugs. It wouldn't return to the same part of a page when you hit the back button and it wouldn't show followed links by changing their color. VERY annoying for eBay users like me.
I'll just wait for IE7 to get tabbed windows.
Go to http://www.avantbrowser.com/ and get tabbed windows in IE6 *now*.
Avant bills itself as a new browser, but it's actually just a fantastic UI modification to IE. It adds tabbed windows, and much, much more. Of all the people I've shown it to, 100% have become converts.
~~t wouldn't show followed links by changing their color.~~
It allows you to change the colors to your preference. It gives you about 50 colors to choose from. I use blue for link and burnt orange for read on Firefox.
Try Mozilla instead of Firefox. I've been using Mozilla for a few years now, and I swear by it. I can't stand firefox or IE. Firefox, as you'll note, isn't even 1.0 yet, which essentially means it's 'beta' quality right now. I have next to no problems at all with Mozilla. I use Multi-zilla to get enhanced tabbed browsing, and a few other plug-ins that make my day go smoother. The built-in mail client is a dream, esspecially the spam filter - which filters roughly 60 - 80 messages a day for me with less than 5% false negatives now. (It requires some time to 'train' it to be accurate) It's also available free at Mozilla.org.
