I was using "Video Speed Controller by codebicycle" until it decided to crap the bed yesterday... Suddenly, if I set the speed to say, 1.5, and then move the video along, either by clicking on the timeline, arrow keys, or number keys, it would slow back down to 1. The other addons based on the same repo seemed to also have that issue, so I'm guessing it's a YouTube problem. Please, please, pleeease keep an eye on that, because the global speed addon is a faff, and I'll keep the 5 stars coming! ❤️

No controls show in the YT video. Some keyboard shortcuts work but I don't need them. I want controls to click on in the YT video.

Is Speeder 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.

Speeder 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.

Speeder is probably trust-worthy. Prefer other publishers if available. Exercise caution when installing this add-on.
