+1 interesting.<p>Started using Opera since ~2000 and really liked it. Really innovative (tabs, mouse gestures, download manager, ...) and fast! Even an email client was included :) !<p>But replaced it with Firefox by the time FF had tabs and was fast enough, due to &#x27;trust&#x2F;privacy&#x27; reasons. For the same reasons I do not use chrome.<p>And if FF keeps disappointing me and Opera gains trust I can imagine a switch :) (hmmh, but how if closed source?)
