User Reviews
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?
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.
Web Video Speed Controller requires some sensitive permissions that could impact your browser and data security. Exercise caution before installing.
Risk impact analysis details
- Critical Allows access to all websites, posing a significant security risk as it can monitor and modify data from any visited site.

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.
Web Video Speed Controller has earned a fairly good reputation and likely can be trusted.
