Still after the newest update there is a bug where when scrolling up in Twitch chat and click the new messages, the video player messes up. When you scroll up the stream shrinks ever so slightly and when you click the button to see new messages it goes back to normal. If you watch the bottom right of any stream you'll see what I am talking about

auto-tab emote completion randomly breaks. the only way to fix it is to refresh the tab. this bug has been around for years now.

Don't say it works for YouTube, when it's not planned to.

Sadly every streamer uses a lot of 7tv emotes. Problem is: 7TV always has extremely long loading times for emotes in my area and most of the time emotes don't load AT ALL or instantly un-load again after closing the window!
7TV is extremely frustrating to use and it only gets worse every week!
ONLY 7tv has this problem! All other emote extensions work and load emotes without any problems!

All emotes except 7tv emotes themselves work...

Emotes always fail to load, autocomplete never works, no emote modifiers. FFZ > BTTV > 7TV
