@jwz Edge is no better. I don't know about Safari. If you want to use Firefox, you're going to need to troubleshoot websites / add-ons from time to time.
IMHO it's worth it, but I've got almost 25 years of experience working with open source projects.
@AlgoCompSynth Well, Edge is based on/forked from Chromium.
Safari/Webkit is OK, though they really deprecated the plugin support years ago meaning a lot of ad blockers stopped functioning. ;-/ Thankfully, not all of them. I think there are more Mozilla/Firefox forks than Webkit though, and the number of Chromium forks surpass both of them AFAIK.
