not the OP, but I have had some webpages that didn't work correctly in firefox. Firefox's market share is lower than 5% and some web devs have opted out of optimizing for firefox. The crypto stuff is completely opt in, I disabled it, added the typical ublock, decentraleyes, badger and clearurl addons and it's basically as secure as modded firefox with the same addons or the shitty firefox port called librewolf with the settings that takes 1 min to set up already done by default, and yeah it's shitty because it takes longer to update than firefox because all they do is to merge from the main branch.

If they asked chromium, let them, why the hell are you chastising people for their preferences.

When the Addon version change rolls in things will be different, but it has been delayed due to the user pushback and I don't think that it will get implemented. If it does, tons of users will migrate to firefox anyway.
