Simple and easy to use. Just wish there was an option to use mouse keys as well as keyboard

It's cool but it makes reddit lag so hard sometimes... It doesn't even work in reddit, so idk whats wrong

Works exactly as described.

i like this add-on because it is very precise but what my complaint is it freezes when i receive live on youtube and i can not hover to find setting back to 1.0/ TY maybe is a quick fix for this?

Easy simple and clean and goes way past 2x on most video/media sites. Simple, does the job.

Very useful, easy to use, lightweight, non-intrusive, not bloated with tons of unneeded features, and simply gets the job done without getting in your way.

worked very nice. But in recent days firefox keeps telling me "video speed conroller is slowing down firefox"
