@jon@social.vivaldi.net I've been using Vivaldi almost since it was released (switched directly from true Opera, because ChrOpera's mouse gestures didn't work properly). Been a supporter for a few years, too. However, unless there's a viable replacement, I'll switch to LibreWolf once uMatrix stops working in Vivaldi, as I can't imagine browsing without it (unfortunately matrix³ is too cumbersome to use [and missing important features], and I'm not aware of any other similar extension).
