Now if you would only listen to me and use ******* Mozilla!!! I swear people, the best piece of internet related software you could ever download is the Mozilla Firefox web browser. Not only is it a fast, clean and smooth running app, it's got a lot of Java, ActiveX, popup, adware, etc protection that the piece of crap known as IE will never have, without downloading a half dozen ancillary pieces of software.
while i would agree with this, mozilla does have it's own issues. it may seem silly, and petty, but my mouse doesn't work properly with mozilla. i have one of the logitech trackball thingies with this little wheel that they call the "webwheel" - it's the little scroll wheel like a lot of mice have nowadays, but when you press it down, it pretty much gives you a little round circle of links, kinda like what's at the top of your browser... basic stuff, like 'home', 'back', 'reload', etc. and i've been using it for a while, so i've gotten used to it. but those functions don't work in mozilla
and mozilla's e-mail client isn't the greatest either. if you have multiple emails - like i do - outlook can check them all at the same time. but i couldn't get mozilla to access all four of mine without going and clicking on "check mail" under each identity seperately. again, silly and petty, but extremely annoying.
well for overall web browsing experience and security mozilla is the way to go. but i do agree with you that it does have some quirks. when i first started using it, the buttons up top like home, stop, reload, back, etc, the little images wouldn't load and all i would get is a black outline. it was a known issue with that particular version and was resolved by the next release. that's the great thing about mozilla, though its a continuing work in progress, you can interact with those working on mozilla via mozilla.org and let them know of any problems you've experienced as well as look up a list of known issues.
i have no experience with the e-mail client however, so i can't say anythign good or bad about it. i used to use outlook myself at home and have to use it at work and its a good program to use so long as you are careful with the attachments that are sent your way.
