Plain Matrix rooms are a bit too foreign to Discord users i’d say.
There’s another alternative being built which resembles Discord a lot more, is federated and as i understand is built around Matrix communities: https://github.com/commune-os/commune-server
Here’s a demo instance: https://shpong.com/
Firefox in general is faster for me than Chrome in many pages
However a notable exception are web games and web based game emulators. They’re a lot slower on Firefox and i get horrible sound crackling whereas on Chrome its much better. It’s been like this for years with no seeming improvement.
For now your best bet is to do the community search in the section at the top of the web ui. for example, choose “All” in the filter and search for “gaming” and it will find all gaming communities on all the intances.
The sub you’re on right now also displays on the right hand side of the post, you can also press subscribe there.
