I just downloaded the latest version of Opera, I have been using Google chrome and really haven't had any problems aside from having a hard time inserting pics into my responses. Do you have any widgets you like and please let me know if you've had any concerns with this browser.
I use Opera, in fact just updated it. It works great for me. No worries so far and I've had it for a couple years. It's not at all buggy the way Firefox was for me. I don't really use widgets much so can't offer much help on that. If they come up with a halfway decent video downloader widget I'll get that, but so far they haven't.
