doesnt work.

Stopped working a long time ago.

Not working!

I did not see any effect.

The standard Firefox option may even be enough. I just noticed I had to change a setting to 'always'. Now that works as far as I have tested.

So for the moment, I disabled the add-on.

Like so many, what once worked beautifully doesn't any longer or only in clunky "soviet" style

I can find no way to access this or to use it.
