Problem with extensions should be sent to the developers behind them. You can find their emails in the extension details, ie https://www.twitch.tv/ext/zfh2irvx2jb4s60f02jq0ajm8vwgka-1.0.12 -> support.
If it’s just you that’s having this problem, maybe your browser is blocking the extensions (ie plugins). Try it in an incognito window and see if it makes any difference.
