The leader of the pack is Mozilla, which is one of the most mature browsers in terms of development and capabilities. Mozilla is the engine that runs Netscape’s Communicator browser which, for many years, was the browser of choice before Internet Explorer overtook it. Prior to Mozilla, it was the Mosaic browser that was Netscape’s main engine. Netscape is still a powerful browser although a bit lacking in certain features.
With tabbed browsing, tabs within one window link to different pages, while other browsers would traditionally launch another browser page covering the rest on the screen. Tabbed browsing is an innovative feature that suits users with smaller monitors and desktop real estate. Mozilla also integrates Chatzilla, a chat function built into the interface.
On the downside, since Mozilla is an open source browser being implemented across numerous platforms, there seems to be no end to the revisions and bug fixes that need to take place from time to time. There’s also some level of confusion with integrating some of the multimedia plug-ins and their newer versions. Mozilla also limits connections to certain ports for security purposes, sometimes getting in the way of the surfing experience.
Mozilla has also spawned a number of clones such as Chimera and Camino that offer similar functionality and speed but are platform-dependent to MacOS as well as for assorted flavors of Linux.
Mozilla remains to be one of the more customizable browsers around; you can design it to look different and substitute its skin as well.
Claiming to be the fastest browser (a claim similar to the one Apple is making with its proprietary OS X browser Safari), Opera seems to travel well between platforms although testing it on older machines, there were noticeable problems resizing the pages as well as redrawing webpages.
One of Opera’s crowning achievements is that it can stop surprise pop-up windows from appearing, which is one of the problems encountered by surfers today, particularly those visiting marketing-intensive websites. If only other browsers could make this option more easily available and configurable to new users, then the experience of trawling the Web for news and images would be painless.
Opera is available as freeware but with online advertisements. There is a version available for online purchase without the dreaded ads.
There may well be more but still in their very infant stages of development. For most users, whichever browser works best in their current set-ups should be the one they would stick to. Owners of newer machines will be able to enjoy Internet Explorer’s advanced technology and multimedia savvy but owners of older machines may be fine using earlier incarnations or even some of these alternative browsers.
