It works, thank you thank you thank you! After a maddening hour of Googling and playing fruitlessly with about:config, this finally, blessedly works. It would be nice if I could set the add-on permanently enabled for all sites, but oh well.

esse Plugin do carlh* show da pra copiar mesmo bloqueado pelo site. pena que desenvolvo site ;/ dmbsites at gmail.com

Does what it was made for and I'm happy with it. No compatibility issues to tell off.

i love simple extensions that need no tuning or calibration.

It's a good addon but it breaks video controls on sites such as Twitter.

edit: Revert to 1.3.6 and it works fine.

Finally found one that actually WORKS after trying out the other ones out there. Thanks and kudos to the developers of this very useful addon! ツ

doesnt work with https://thermalimagingcamerareviews.com/

Very simple,minimalistic and also clean desgin.
