@fitzydj: Thank you! I couldn't find any version but 38.4, but installing the extension from the Chrome store instead of the Opera store worked. Although I had to go and redo all my settings, because it claimed I was installing it for the "first time," which is annoying, but at least it works now. Appreciate the tip.

@loulou6: Yeah, it's not an ad popup. It's the Opera popup that alerts me that I've installed a new extension. But it keeps popping up over and over. No way to shut these off it seems, but definitely buggy.

@loulou6: Same problem. Opera won't let me use it. Same error message. And I get an annoying "FB Purity has been added to your extensions" popup message every few minutes, even though it's not working. Frustrating.

Since this update yesterday, uBlock is not working on any site for me. Been using it for years without problem, but suddenly it's just not filtering anything. Not sure what's changed, but it's been broken for the last day.

Every time there is an update, I start getting inundated with sponsored ads in my feed again. It usually takes weeks for it to start filtering them properly again after each update.

@timleland: App was working again briefly, but has once again stopped updating the temperature automatically for the last few days. I have to constantly click on it to get it to update. Seems to be fairly hit and miss overall.

Been down for almost a week now. Site is unreachable, extension no longer works. Not sure if it's dead or not, but I'm sadly going to have to replace it since it's not functional.

Seriously, I am getting so sick of Opera and Flash not playing with each other every time there's a bloody update. This problem happens time and time again. You'd think they'd have figured it out by now. I'm seriously considering going back to Chrome if Opera can't get its game together. I can't even listen to a bloody hockey game because Opera won't allow Flash to play.
