deliria, very well said. I've used Opera since pre-5.x days and that's one of the best features it's got. I like being able to disable pretty much any animation/scripting at the click of a few keys and then being able to re-enable after whatever it is has been done.
As for 'not killing popups', that's where Opera shines in my book. "Only allow requested" in Opera lets through those I want, such as phpBB login/pm windows and the like. All the others can rot! I also use the email client in Opera, which knocks out 99.99% of the "viruses" that are spread through Outlook* (I'm refering to .vbs and other macro viruses).
