Which is Better, Firefox or Opera?

Roblimo writes "Firefox and Opera are the two most popular cross-platform Web browsers. Each has its own advantages and disadvantages. Kris Shaffer tested them side-by-side on SUSE Linux 9.1, Mac OS X Panther, and Windows 2000, and decided that your choice may depend more on what you *do* with your browser than anything else, unless (as is the case for many of us) Opera is off the table from the start because it's not open source."
