I used this tool for several months and and had a good experience with it for a long time, however, the recent changes make it unusable as an extension without paying.

Prior to this, I would have given it a 5-star rating, and should have, but I cannot currently do so given the price.

I wish for the best and hope that it does well, though I will personally not continue using it for the foreseeable future, even if I understand the reasoning behind the changes. If you are willing to pay for its services however, it is very high quality and I experienced few, if any issues with it.
