Operetta

I've had an opportunity or so as of late to look over the various browsers... the big names. Those would be:

Explorer: With the most market share, Explorer is a serious player.
FireFox: Mozilla's salvo into the browser market isn't too shabby, and sports some innovations that kept MS on its toes.
Safari: As far as I know, Safari only works on Macs, and is the equivalent of Explorer in many regards. The other browsers I've only used on PCs.
Opera: I'm addicted, but it's a smaller name, with few interested in switching to it, for some reason.

I'll start into this with a bit of a disclaimer: I don't like Microsoft. Don't get me wrong: I understand why they do what they do, but I'm not a fan of folk that seem less innovative than Chimpanzees. Plus, as I sit here, Explorer keeps trying to open up some ads, and I feel like I'm being nasally raped by Bill Gates.
thpppt! The upside is that most sites run with this one in mind, so if you do a lot of browsing for, say, business needs, you'll probably be happiest with this.

Firefox, my browser of choice until recently, had tabs first, featured a supportive community, included widgets (which they may have picked up from Apple), and actually had some security to it that blew Explorer out of the water. The only reason I kept Explorer on my machine after Firefox came out was that I still wasn't certain about that whole "necessary component" thing. I use Firefox at work, but only because they don't want me to download Opera. This one gets more support, but both it and Explorer have their own standards. Expect some glitchy pages, but only a few.

Safari: Safari is pretty comparable to both Firefox and Explorer as far as "features" is concerned. I consider it more secure than Explorer, and the widget selection is better. I'd expect Apple to have better support, but the web community does not really care for Safari.,

Opera: Widgets? Tabs? So last week... have you seen speed dialing? The "browse from command line" option? Built-in note taker? Zoom function? You can validate code with a few hot keys... did you see that? Fully frickin' compliant with the W3C standards at the time of release?

This is not to say that Opera isn't without problems. I've noticed some glitches(the cursor suddenly relocates) while typing this that I attribute to either it or the random Explorer pop-ups. Either one is plausible to me. Even though Opera is fully W3C compliant, it isn't Explorer or Firefox compliant. You may still notice some differences on sites that use either as a basis.
