Love the functionality this add-on provides (especially the custom themes and ad block are great), however sometimes it freezes the tab. Happens about 3-4 times a day with admittedly very heavy use, so it's bearable but nonetheless annoying.

neat settings and capabilities, but it's unusable because it makes firefox crash during every video. nice try though

favorite feature is that you can read comments while watching the vid don't know how well the add block works since i use add block but great app

I use only the boost audio and loop button, with this settings, it's really odd to have just two button on the bottom of the page, it would be better to add it on the player toolbar itself !!! (or like the "maximize video" userscript from icycat (冻猫) = attached on top right of the player and visible on hover only)

Not getting activated. I'm Using Firefox in Linux Mint 20 Cinnamon.

Firefox version: 80.0 (64-bit)

Overall good, so far. will be testing for myself. the fifth star is in queue!

В сентябре 2020, обнаружил, что приложение заработало...Без него как без рук, всё как-то неудобно было.
Единственно что я не нашел, как исправить, изменилось направление прокрутки страниц с помощью колесика мыши, с вертикального на горизонтальное (только на ютубе)...не категорично для меня, но это произошло после установки приложения. Хотелось бы исправить сие.

It works very good with excellent configuration options and it is also on Google Chrome.

Says what it does and does what it says. One of the best Firefox add-ons right now.
