I receive all of Mozilla’s newsletters and I seethe whenever I see them demanding that more be done to sanitize online expression, which is all the time. That said, Chrome is hardly an alternative given Google’s approach to moderating YouTube.
Edge is a privacy disaster, sadly. You can't even make their sync fully end to end encrypted, and that's the tip of the iceberg from startpages to hardware-based browser IDs. Absolutely amazing product otherwise, but yuck.
