I personally recommend the stable version. It has integrated Adblock and sponsorblock. The dev is very responsive when issues arise like YouTube breaking stuff.
I'm guessing that's not the reason for the downvotes. Even though this is the reddit community, Lemmy users generally just don't care about what happens on reddit.
I don't know the number, but you can definitely brush too much. My sister in law was obsessive about brushing her teeth so much that the dentist advised her to lay off as she was damaging her teeth enamel.
