Vast majority of sites work for me (librewolf), but for the few that don’t I also have Vivaldi installed

My favorite e-reader is Cool Reader(granted, it was last updated 3 years ago)

My favorite music player is innerTune (however that is more for playing YouTube vids as music)

Self hoster of Invidious, I’ve just setup a docker instance with a Watchtower docker container running too for auto updates. No real maintenance needed.

There are definitely times where things will stop working for a bit (due to Google shananagans) but the devs seem on top of it. So it doesn’t take too long before it’s working again.
