Does not work, they block for 24hrs and then ask for payment. I think this is a scam.

Worked for 24 hours, only.
I have now deleted this rubbish.

I don't necessarily have an issue with extensions requiring payment, but that this one doesn't disclose up front that it is not free is just dishonest. It only seemed to work half the time, and then not at all- because I need to 'make a payment to continue using it'.

Seriously, if it at least stated in the description that it's a paid extension I wouldn't have been moved to set such a low review, but dishonesty from developers is a big red flag if you ask me.

It doesn't work most of the time, and now, after an unwanted update, the authors of this barely functioning add-on actually have the nerve to want money for it.

Love it. Just works.
