great

Does exactly what it says on the tin, love the improved performance and ability to switch to live chat by default.

HyperChat is a must-have extension. YouTube's regular live chat box can slow down your browser, especially on non-Chromium-based browsers. HyperChat replaces the chat box with its own, more performant version. For those who watch streamers with community or hired chatters who post "live" translation comments, such as select streams from Hololive, this extension features a custom interface to display those messages, making it easier to follow along with the dialogue.

Makes youtube chat efficient enough to actually be usable on my tablet

This made my day, old laptop(i5 3210m) now can open chat on youtube live!

Fixed the memory leak.

I won't knock a star off this really good add-on, but it's admittedly not what I was looking for.

I was hoping that this add-on would come equipped with some way to write filters for chat, as I simply want to disable EN comments on JP streams (the two fanbases behave very differently). If they added this, I would be so pleased. Otherwise the only other thing I could ask for is more subtle branding on chat because it sticks out like a sore thumb. Still, these are not significant downsides at all.

Absolute hero of an extension! I was having horrendous memory leaks on stock YouTube on all browsers. Finally tracked it down to the live chats of live streams. Installing this extension instantly solved my problems. Amazing that third party developers can consistently do what the biggest companies in tech consistently can't. Well done!

Works perfectly for me ty
