@jon Definitely have! While I use Waterfox as my day-to-day choice mainly due to familiarity with Gecko, Vivaldi's been my immediate backup and as I get more and more comfortable with it, it might end up being the new main. I've been loving the features you guys offer.
Less worried about the old MV2 extensions like uBlock Origin as I once was as I'll just simply not use a site or service if the built in blocker, with some extra filters, can't do the job.
