This Add-on can not work Today? At Aug-11, 2020.

Я не понимаю, почему автор дополнения молчит и ничего не делает? Ничего не работает.

does not work

Not working! The addon that is working is: "Good Old YouTube"

This extension is the only known way (as of July 16) to restore the Classic (2012) YouTube design on all pages, including videos, channels, and the homepage. However, it requires some special configuration to work. Instructions: https://old.reddit.com/r/youtube/comments/hrzooy/old_youtube_layout_is_gone/fy8vh1e/

Masih berfungsi hingga review ini ditulis 16 Juli 2020. Cara menggunakannya seperti ekstensi lainnya hanya saja ketika ke YouTube jangan menuju ke Halaman Utamanya www(dot)youtube(dot)com tapi copy paste video url YouTube baru YouTube Classic ke Trigger. Hanya saja deksripsi masih kepotong sehingga nggak bisa di baca sampai habis.

can you please fix the add on ? thank you for your time.

GUYS IT STILL WORKS (kinda). So as of 7/13/2020 the entire legacy version of youtube will only work with this addon on firefox (homepage, videos, channels, search page etc...). Basically what you have to do is copy and paste a youtube video link into the omnibar and only browse ON THAT TAB; so if you open a new youtube tab, it will go back to the newest layout. As someone who is generally disgusted with major UI overhaul changes on any platform (and oh boy has youtube had its share of those) I tend to hold out as long as possible with these kinds of tricks.

Does not work anymore (July 2020)

Works fine. I need to refresh to make it work.

unfortunately this version doesn't seem to work at all, there's no way that any old youtube design will appear....please fix the bug! else, its a great tool overall-keep on developing

Расширение хорошее, но поскольку Ютуб постоянно что-то переделывает, то и расширение порой работает криво. Сейчас, к примеру, уже неделю не всегда отображаются комментарии под видео - просто висит бесконечная загрузка их. А отключаешь дополнение - всё нормально становится, но вид ужасный.)

It works and I am happy with it, but it kinda malfunctions. For example, whenever I open YouTube in a new tab the new layout is forced upon me, if I refresh on the main page it still stays in the new layout. I have to go to an video then refresh it and only then the old layout will come back.

Ютуб опять что то обновил, и дополнение перестало корректно работать буквально час назад...
