After reading the Firefox thread last week, I made the switch from Opera. Compared to Opera I think it's lacking in some functional/usability areas. Mostly small anoyances that I can live with. The big plus is that I have found several sites that were incompatible with Opera that work fine with Firefox. That alone will make it a keeper.

I'm experiencing some behaviour that I can't figure out. I'm a tab kinda guy. So in Opera I'm used to clicking on a link in a flyertalk thread and it launching a new tab. Firefox launches a new window - very annoying. I've been all through the Firefox menus and can't seem to see where I might change an option or two to fix this. Anyone have any idea?
