Small update I almost forgot to make.
As some may already know, I now use Brave Shields in Brave itself.
And I as of today I use Adguard in Opera One. I did try that out already a short while ago, but I saw some things happen on YouTube while visiting channels I follow. They would not load correctly, and today I found out that it actually was Dandelion's Annoyances List causing that to happen? I can not remember ever activating that list, yet it was? Anyway, after I deactivated that list all the YT channels loaded as they should, and as such there was no reason for me not to switch to Adguard.
Although I still hope there will be a uBlock Origin version for Mv3 in the near future.
