These warning have been out for years, so I have been using Opera & Firefox for years...and 2-3 others. Chrome doesn't do enough yet to suit me, but I suppose it will. "SeaMonkey" is an offshoot of Firefox for those who want a 'complete suite' in one application.

If you really want a versatile browser, try "Opera Unite". It is 'different' than Firefox, but has SO many virtues. I see no value in making browsers an 'either/or' decision when both have different features.
