Annoying like no other thing :
Got an old PC struggling with some contents and this extension now actually forces the definition instead of respecting user's choice whenever a definition change is needed.
Basically unwatchable videos many times..
Old behavior was superior by far as it respected the changes made after the module had done its work.

Since a few days ago youtube randomly refreshes over and over. Disabled the addon for now. Was good until then.

only quality feature works;video speed feature doesnt work

it works on volume level but never works on video quality. video speed changes to 2 when i set it to normal.

Please fix the size of the widget button on right side (more tools area).

IMO this was the very best youtube addon. But as youtube kept changing and this addon was no longer updated, not all the functions work anymore :(.

Pensava peggio

Can't find any link where we can report bugs, so I have to do it here: it seems that since a few days, this add-on doesn't adjust the resolution on Youtube videos anymore and I don't know if it's just on my side or indeed broken. Until then it worked fine.

Good

Works as intended. However it opens a tab to the creators website pleading for donations every time it updates.
