My 7TV broke down pretty much, this is an example of the error message I receive when trying to login into 7TV through the 7TV badge on twitch. The 2nd picture is how my chat is now, with only being able to see the last 2 messages despite the FFZ setting of scrollback being overriden by 7TV -which happens to be 150-. Last but not least the badge near the chat settings button is gone and the emotes are gone as well.

for first one try to login on 7tv.app first
for the second one does changing manually the scrollback length not fix the issue? 
you can enable badge on chatbox again in settings
Already tried to login directly through the website and this is the message that pops up:
I think website may have issues atm, try again tomorrow maybe (loggining into extension doesn't give you much either way)
smol update: for some reason ffz is blocking(?) 7tv, disabled ffz and the chat works fine. emotes unfortunately not working/showing text only.
Update: 7TV working again, thanks #developers for fixing it.
Update 2: 7TV broke down again after trying to enable FFZ back; when the picture was taken i managed to login into the site normally and after that, that "failed to fetch" error popped up again and kicked me out.
Last update regarding the problems i had: As of today (April 25th), 7TV is working fine. Currently using only BTTV + 7TV since i dont know if enabling FFZ again will brick it.
if you enounter 7tv extension fully not working, just do chrome://restart
