Thanks, I somehow managed to scroll past that like three times. If anyone else needs to know, it's settings > websites > video pop out.

I had the pop-out button disabled for a while but it's back with the new update and I can't figure out how to turn it off. Anyone know how?

I've been having the same problem. I couldn't fix it myself but until you find an actual solution you could either disable the backspace keyboard shortcut (Settings > Browser > Shortcuts > Configure shortcuts) or hold alt while pressing backspace.

I recently updated Opera to version 40.0.2308.62 and I've noticed that the autocomplete when I'm typing a URL has replaced the first result for certain letters with other terms. For example, I used to be able to just type Y+Enter and get taken to YouTube in no time flat, but now doing that takes me to Yahoo. Is there any way to get rid of the recommendations for Yahoo, Bing, DuckDuckGo and the like?

That did the trick, thank you!

I recently updated Opera to the newest version and found out about the new pop-out video feature. It's neat, but I know that I'm never going to use it so I'd like to disable the big button, but I can't seem to find a way to do so. Even adding every possible version of a URL to the detached video exceptions thing doesn't seem to do anything. Anyone have any advice?

Didn't realize there was an update -- I just installed it and everything's working fine! Thanks so much for pointing that out to me, I'd have been totally lost if you hadn't!

Up until a few weeks ago, I never had this problem, but ever since upgrading to Windows 10 I haven't been able to watch YouTube videos, listen to songs on things like SoundCloud, or even click on anything that makes any kind of a noise without it being jittery and stuttering. SD video tends to be alright, unless I open another tab, or scroll down the page, or do anything at all, and HD is right out. CPU usage also seems to shoot higher than it should at times, but I haven't actually been keeping a super close eye on that.

The thing is, though, that it's only when it's coming from Opera. Like, I'm able to listen to music in Chrome while I browse with Opera and it runs fine. I've tried disabling/re-enabling Flash, hardware acceleration, and all of my browser extensions and nothing works. I'm running the latest version of Opera (31.0 while I'm writing this) on Windows 10, but so is my friend, who's having no problems whatsoever.

Thanks in advance for any advice you can give me.
