Temporary solution until Firefox fix the Twitch high CPU usage issue. PD: how could I see the live channels, I don't see it.

you can't follow raids but it works great

I've just downloaded this extension so I can't comment on all the features. But... I had been having this really annoying issue with the audio and video being desynched for Twitch in Firefox. After trying all kinds of solutions that didn't work, I installed this extension and it solved the problem. Very happy! :)

Please add 7tv.app emote menu

Used to work great until today, the button on the top right to switch to the player doesn't appear anymore.

Temp fix : go to your extensions > cogwheel top right > debug extensions > scroll to the Alternative Twitch player and click the manifest URL> replace /manifest.json by /player.html?channel=
This should work for now

not working anymore. Working fine yesterday

It's almost perfect, but you can't whisper people with this addon enabled.

Huge improvement over the default player, excluding the odd theater preference. Videos load way faster, buffer less, and adds extra customization. Also, it solves the vanishing controls bug, which is why I used it initially. (EDIT: Doesn't solve the vanishing controls for VODs)

Хорошее дополнение, уменьшает нагрузку на ЦП, удобное управление, но когда стример кидает рейд, то поток просто останавливается и не перекидывает на другой канал. Не хватает ссылок на описание, видео, расписание канала.

*final conclusion

ive been using alternate twitch player between oct '20 and february '21 due to twitch overblowing their ad deployments. however over the past month ive switched back to the standard built in twitch player and ive been faced with, well a reasonable amount of ads really. and their video quality has improved drastically (better than alternate player quality in some cases). just recently theyve FINALLY aligned the theater mode player to have even top and bottom black bars (which has prompted my final conclusions here) so i must say that as much as i now fully recommend sticking to the original twitch player, this still has its use cases as being a very efficient player (5w on my laptop compared to a jumpy 6-9w with the built-in player) and as well being very responsive and less obtrusive. however with the lack of FFZ compression and the comparative quality of twitch's built-in player, i will use theirs for the foreseeable future.

thanks for the extension which saved me for some months from pulling my hair out.

Only thing that works to block all ads and purple screens on twitch right now. The volume is quieter than the default player for some reason, and the latency is a bit worse, but it's a small price to pay.

EDIT: Of course it stops working the day after I send this review. I assume twitch changed something but this extension is broken for me right now.

EDIT 2: Working again 2021/01/25.

Great player with a lot of thought put into it, but one star ding for lack of pop-out video support via Firefox picture-in-picture. ( https://support.mozilla.org/en-US/kb/about-picture-picture-firefox )

UPDATE: It seems raiding doesn't function correctly, when the twitch channel raids another channel it doesn't swap to that channel's video feed when the first one stops broadcasting. The chat does swap, however.

very nice addon, way less cpu usage & ram when watching a stream ( twitch use WAY too much ) one little thing, it seems like a message "hiding ads" for 15sec made his appearance,and it totaly stop the stream, which is a bit annoying. ( ok for now its unusable saddly as its like stop every 10min for that "hiding ads" thing, no idea what is happening or the reason )

Works most of the time

Love the extention, Sadly twitch patched it recently.

Up until maybe the 25th or so, the player now gets ads when it previously did not. I assume it just needs an update, but otherwise a great player that I've been using for a while now.

Great extension, only issue is the slight additional stream delay. Otherwise no problems
