Interestingly enough, Microsoft just said they won’t be updating Internet Explorer any time soon. All this while the Mozilla browser just keeps getting better and better. It is quite possible that “the browser wars” that were supposedly over a few years ago may be rekindling. There is no doubt in my mind that Mozilla is the best browser I’ve ever used, spam filtering, tabbed browsing, no pop-up ads, and 100% compliance with W3C HTML (this means pages render exactly as they are coded–it is common that some pages are coded incorrectly so they display in a sensible way in IE) are key reasons why.
Remember, Mozilla is free software and can be downloaded at no cost. If you spend any time at all on the ‘net (of course you do, or you wouldn’t be reading this), you’d be foolish not to at least try Mozilla.
