  • Please consider adding the ability to change the *Keyboard shortcut* for Cinema Mode.

    Alt + Shift + End is mission impossible on my laptop... :'(

    Love the addon,
    Thank you! :-)

  • For some reason it stopped working on my current esr build 52 of firefox So I searched for older versions of EFY (ALL versions including the latest were working yesterday!!!!). I have compatibility checks disabled in about:config. I installed one from 2018 and it works just fine except for the autoplay pause that only kicks in after 20 or 30 seconds for each video I open in a background tab instead of instantly. This is Youtube's aka Google the Anitchrist's fault.
  • I'm very happy with this addon it gives me what I need on youtube (slow/fast speed, default *4K, HD).
    I wish this kind of add-on can be added on android ;) (mmh maybe it can)

    *Sometimes, it doesn't shows the 4K as default (why?).
  • This addon is very helpfull but it has some bugs - it spams many same elements (style and script - including usermade) into head of document. It can make browser slower as well as it takes more memory.
