"Installation aborted because the add-on appears to be corrupt." Updated 2 hours ago and it says this.

I've been using this add-on for a few years, and it is fantastic. The user interface is the best I've encountered so far because it is simple, versatile, and fast. It executes what it does flawlessly, but I give it four stars because it is missing a couple of QOL features that could. I think it should have an advanced setting page where you can set defaults on a per-domain basis, so, for example, every video on [domein.tld] starts at 1.6x speed, and the ability to make it so you can choose to keep the speed consistent within the same tab after a reload.

Until recently I thought this was the only one that worked in Prime Video.
It is not.
And compared to Video Speed Controller, this one doesn't manage to make Prime Video remember your preferred speed for the next video, so if you're like me and you like to binge a series in one go, you need to set the speed again at every episode.
Not ideal.
But I thank the Dev for their effort, it was much appreciated until now.
If they manage to make the speed change permanent, I will use their addon again because it's visually easier. I like visual controls.

Unlike Chrome/Edge, there is no speed badge.

Fast

cumple su propósito, funciona tanto en Netflix como para Amazon Prime Video que era lo que buscaba.

Thank you. This is the only video speed up/down tool that works with formed.org.

Could you add Ctrl+mouse wheel up/down, (or a configurable keyboard shortcuts), please.

cannot remember playback speed of each individual sites. I want youtube video to play at 1.3 but that speed carries to ALL video on ALL sites, very bad extension.

It is very easy to use, simple but powerful, good add-on. Hope this add-on become popular. Developer should add some shortcut to quick access.

Very wonderful donation of 5 *

Must be shortcut key.
