Excellent, does exactly what i needed and that is to set video speed as globally (most/all videos) as possible.

I initially thought that I can only set the speed for all the tabs. After reading the description, and digging around a bit, now I have realized that I can set the speed only for one tab(as I only need it for spotify) which is really good, this extension is exactly what I needed

very nice. it's light and remembers speed globally (unlike others, which don't or are not updated)

挺好的

Because of today's website update, the page acceleration of Baidu's online drive can't be used，Please solve it quickly！

One of the most useful Firefox Extensions

It works like a charm. and the extra things like pinned tabs with different speed is a bonus

nice
