@Opera-QA-Team That's great! Thank you for listening and caring.

@Opera-QA-Team Maybe you have an idea how to handle the Facebook issue with not loading feeds and some other annoyances with the new ad blocker turned on.

So for me it seems there's only to alternatives:
either turning ad bock off for Facebook generally (which isn't what I want to do, actually) or just using another browser for it.

What would help me: turning off the specific filter list that breaks Facebook for just this site. As far as I see it, you can toggle on or off filter lists only generally and for all sites.

Besides, there's no such issue with Firefox and the uBlock Origin extension.

The Facebook-issue hasn't been resolved, actually. I can load about four to ten posts until I get an error message like this:

I don't know which filter is responsible for this. But as far as I know you can't turn on and turn off filters for each site. You can only disable the ad blocker generally for specific websites.
But as I found out, doing this in the address bar will make the button disappear from there for this very site as well. And to bring it back you have to go to settings and delete exceptions (for Facebook in this case).

@Himmelsschlingel I've seen, that the list uBo Cookie Notices has already been removed.

Facebook doesn't load either, I'm afraid. And disabling the adblocker in the address bars let's the icon disappear for the very site as well. Tested it with Gmail as well.

Awesome. Seems to work fine out of the box. I noticed that the list uBO: Cookie notices was unchecked by default. And after enabling it, I ran into some serious site issues. So I think it's better to keep it unchecked as in the default settings.

@Opera-Security Thank you, I've already done that. Very interesting read.

Hallo Dieter, das ist mir, ehrlich gesagt, in all den Jahren bisher noch nicht passiert, dass plötzlich alle Schnellwahleinträge komplett weg waren. Manchmal kamen noch einzelne Werbekacheln hinzu, die ich nicht haben wollte. Ärgerlich genug, aber dass die Schnellwahl komplett zerschossen wurde, habe ich so noch nicht erlebt.

Du sprichst wahrscheinlich von der Desktop-Version, oder? Windows?
Hast du Sync aktiviert? Und nutzt du noch andere Opera-Versionen auf einem anderen Gerät?

Ich weiß jetzt aus dem Stand auch keine Lösung. Aber du könntest zumindest deine Lesezeichen exportieren und speichern und ggf. wieder importieren, wenn dir das Problem wieder widerfährt.

Es hört sich jedenfalls nicht nach einer normalen Reaktion an.

Thank you for bringing the post back again.

I have to add, that it worked once correctly with ad blocking disabled but next time not.
And with VPN enabled it surprisingly worked as well.
