In terms of self harm, the only "safe space" that should exist should be one that helps the person get the help they need - and the only kinda space that actually fits that criteria is often the relationship between a trusted stable friend/family member or a therapist. A space with only people struggling will end up as a toxic feedback loop that pulls everyone down.
Manifest v3 was why I switched to FF a while ago - it was going to only be a matter of time even with the delays so I figured I should switch early. I still like how chrome looks a lot more and wish we had tab grouping, but google can take uBO from my cold, dead hands.
