would be better if it was compatible with all browser

Does the job!

Super

Nice

Could you provide info on what is collected by you on users? There are files in the addon loaded from your website(s). Is this necessary?

I downloaded the add-on based on popularity. It did not detect the video on twitter. Nor does it accept suggestions as to where the video frame is.
I suppose it is Windows oriented (I use it in linux).

perfeito show

Does exactly what I need it to, with no problems whatsoever. Probably my favorite Firefox extension!

Thanks

Awesome learning tool. Repetition is the key; having limited access to internet gives such little time to review... Thank you for the opportunity to learn off-line.

Fonctionne a merveille, je recommande.

ne fonctionne pas sur youtube

This extension is very efective.
Thank you.

Works great, but thought the developers might want to know when I run a virus scan with Malwarebytes, it flags the .xpi file for this add-on as a potential threat.
