its mediocore... after i got rid of it (i belive) that the speed of the videos got fucked permentally, plz help

The functionality of the plug-in is great, but performance is unfortunately awful.

Admittedly I am a person that regularly has over 30 tabs open at once, and noticed Firefox's general performance drop when open for long periods of time to the point of requiring regular browser restarts.

I've had no performance issues after disabling the extension, so unfortunately will give it a low rating.

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?

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

Used to love this plugin but it seems to be causing issues with Paypal. It shouldn't be touching paypal! Cause for concern.

The plugin works very good, but it has access to all websites and strangely when activated paypal signins do not work anymore, which is i find strange

It continually slows down websites that don't even have videos on them. e.g. google docs continuously has problems running when I had this extension installed. Removing this extension solved the problem. Why is it even running on the page?

I can’t use it..why?

each press of the button expands the video screen into full screen mode, and then the next button decreases it to normal dimension. entirely frustrating and unnecessary.

conflict with translatesubtitles.com, the translate box dont show up when using TRAN SLATE/EDIT SUBTITLES section, found out cause by this extension, disable it the problem gone

After the update, it stopped working :(

Reverts to 1x speed when changed to full screen or back.
