Not in Firefox (to my great annoyance)

I use Firefox, and I don't have issues sharing the screen with Discord

Screen sharing works in Firefox, but sometimes the (terrible) websites/apps only care about Chromium, even though it'd work on Firefox.

I use Unified Remote (https://www.unifiedremote.com/) for this, works great.

Glad to see this app is still kicking. I used it a decade ago in college to control my PC while laying in bed and watching movies.

I agree with this sentiment, I also purchased the pro version and it's the only app I ever bought.

It just works.

I'm interested as well!
