Really? Why’d Firefox remove such a useful feature?
Security concerns? Or no one maintaining it?

It’s cool.
I currently catch up on news with it.

Firefox has RSS radar extensions that can help find rss feeds in websites(that don’t really show/mention it on every page)

VLC is awesome. Rcently started getting frequent updates too.

MPV is another nice one. Tried it out recently. The user script option seems very cool: SkipSilence, SkipChapters etc.

VLC for vids and audio I want to watch normally and MPV for ones where I want SkipSilence(Got used to that feature thanks to Newpipe and Pipepipe)
