All of this may beg the question: What add-ons would we like to see?

One that doesn’t exist is QOI Viewer that would render the Quite OK image format into a png for Firefox to display.

It’s very specific but I’d love an auto-skip intro add on for Plex like I have for Netflix.

Plex has that feature built in. No idea if it’s included in the free version though. It works pretty by analyzing sound and it’s pretty good.
