i wonder if this extension is a fork of Igrigorik's. 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), not all of the video screen. 2- hotkey for preferred speed (for example i need 2 different hotkey for 2 different speed)

few things i wanna suggest as a feature. I like the mouse-hover-scroll, but over the video is sometimes inconvenient. Better would be over the add-on ui, maybe with a 5em padding and an outline to show activity. Also would like to add it to the left corner (with some padding). Otherwise, works quite well. PS: sometimes the icon isnt showing up in the url bar, although the overlay exists. In such cases, the program doesnt work. Also, i find it a bit inconvenient with the 2x button. Pressing that button from default, makes it 3x speed. Personally, i prefer something like 1.7 or 2x, and to get to that, requires at least 2-3 clicks. The UI is also rather small and half opaque. Since there is the option for it to disappear, i think transparent icons is unnecessary PPS, also wanted to say regarding pinning the icon mentioned in another review by Julian, the icon is in the URL bar; not the toolbar, and theres no option to unpin; just manage or remove extension

Would have been 5 stars if it was possible to hide the extension icon in the url bar. Its taking unnecessary space and is always visible, I don't want that!

Is Web Video Speed Controller Safe?
