@karebu i do the same for youtube but not google and ive never had an issue with that, i think sometimes i do get stuff because im using a hardened firefox profile though that could be it
it's also nice to see a non populated share menu, for some reason the share menu on my old install had one of my ex's friends that i definitely only texted once, probably when i first got my phone 😭 and it wouldn't go away after removing her from my contacts
idk how to describe it but factory resetting my phone made it snappier ? not faster, but snappier. i guess that's what having not-full storage means, and probably some background services that i didn't need running.
