User Reviews
it's funny that french is default language even though descriptions are english.
for a 5 star you need to add these features:
1- control playback speed with mouse scroll while mouse on top right corner (where extensions ui is)
2- hotkeys like preferred speed (this example is necessary)
3- double clicking on extension's ui enables fullscreen, must be fixed.
i also wonder if this extension is a fork of Igrigorik's.

You're a lifesaver for this, video speed was the only feature I couldn't cancel my subscriptions for and now that I found this simple but effective tool I can finally start saving my money lol. Thank you so much!
Edit: Thank you for your response! I indeed do have some feature suggestions for it:
-Ability to change the floating icon position, it gets in the way of the full screen button at the right bottom and often times making it inconvenient to keep it there.
-A mini form of the speed slider for the floating icon would be great, allowing to do faster changes.
-Ability to customize the speed toggles, from what I see it's always 1.00x to desired speed, adding alternate speeds options to the poll and customizing the ''default'' speed would be nice.
Things that could improved:
-The keyboard shortcuts doesn't work, like alt+s opening the Hi(s)tory pop-up on the menu bar like the Firefox default and alt+v opening (V)iew one, also alt+up/down buttons doesn't work at all. I'm not sure if the keyboard shortcuts are supposed to be manually configured by the user or override the existing ones which may require user data, because if it's the latter it doesn't do it. If it's manual or optional I'd suggest using other keys for those two it so it wouldn't get in the way of other existing keyboard shortcuts.
-When clicked too fast more then one times to change the speed to the speed control panel around the videos; if the website does has a double-click-to-fullscreen thing like YouTube, while it changes the speed, it also causes the video to go/exit full screen accidentally so the user click penetrates the panel. This doesn't happen on the floating icon, so I'd suggest making the clicks on the panel buttons work like how it does with the floating icon if it's possible.
That's it for now! Thank you again for this extension.

Is Video Speed Controller Safe?
Risk impact
Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.
Video Speed Controller requires some sensitive permissions that could impact your browser and data security. Exercise caution before installing.

Risk likelihood
Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.
Video Speed Controller may not be trust-worthy. Avoid installing if possible unless you really trust this publisher.
