Good call. It's especially good for those unpleasant emails.
It was forced onto one buddy's computer and wrecked a lot of links. I repaired them manually, but ultimately Ayieeeeeeeeeeeee! (er, I mean "IE") is a massive pipe perfect for pumping sewage onto your hard drive.
I've been using Mozilla/Firefox for more than four years, and highly recommend it. (Be sure to get Thunderbird for email too.)
I too use Firefox, almost exclusively. Another good browser is Opera 9. Version 9 is much better than previous Opera versions. It has the fastest Javascript interpreter I've found (faster than either Firefox or IE) and is mostly compatibile with Firefox.
For email I use Gmail. I like the way it streamlines the workflow and organizes your mail. It also has a highly effective spam filter. I mostly use it thru its AJAX web interface, however, when composing mail, I sometimes use Thunderbird. (The web interface doesn't support imbedding images in HTML mail, however, the web interface displays them just fine. So, I just start up Thunderbird, compose, and send.)
Good call. It's especially good for those unpleasant emails.
My IT guy for my Mac department told me that Quarrelsome no longer supports Eudora mail and I should switch to Thunder bird. I'm glad to know he wasn't talking about wine...
