This addon works. I guess there arent many addons like this for ffox 57.
I am adding 1star review, because there are popup ads, that will display for no reason.
This is not mentioned in the addon about section. There is also no option i can see to donate and disable the ads. Is this even allowed, for addon to add popup ads? I have never seen it.
If its allowed and it will be added to the about section, i will update this review.
