Works great for a while, then YouTube devs find ways around it again unfortunately. Like today, it was fine until I restarted my browser then YouTube started spamming me with ads. Adblock is great, YouTube sucks.
Also the options page does not appear to be loading on Opera for some reason.

@avgariat I'm having the exact same issue.
Frankly if Opera thinks it's up to them what websites I can and cannot view then I'm just going to stop using Opera.

@adam1709 I had tab scrolling enabled in a previous version via flags I think and that suddenly stopped working when Opera autoupdated a few weeks ago. I updated to 88 in the hopes of getting the feature back but it's never worked. When I go to settings I also can't see an option to enable tab scrolling either.

I'm currently using Opera 88.0.4412.27 but I'm not seeing the option to enable tab scrolling.
Also the changelog link does not work.
