I don’t even pay attention to it, the moment I log into YouTube and Vivaldi stops blocking ads I’ll switch to FF. I’ve already got it set up, V just works faster and takes up less RAM than Fox with the equivalent extensions (minus UBO cause V has ad blocking built in.)
Until then it’s just reactionary fear mongering, this same crap was floating around last November/December claiming that it would break in January and I’m still here waiting for that day to come.
