I figured it out. Fuckfox doesn’t sync extension setting like every other browser sync in the world.
Now I’ve got to go enter everything manually into all six of my machines like it’s 2005.
Ignore me.

I didn't know that, just synced like coupla weeks ago but didn't notice if the extensions did not sync. I spent an hour though, on changing the new tab, as I like it with videos of waterfalls and forests - can put loads of videos, changing every 5secs, just to give my eyes some rest - cool extension
firefox good for me, but no vertical tabs though, need to install tree-like tab extension
Don't know if it's a good idea to sync your private key through a cloud-like mechanism.
