It had been a really useful extension. But from the day I updated to FF 76.0.1 on, It's not working at all. Please fix this issue, since some depend hugely on this. Never thought, I'd have to rate this with 1 star since it worked absolutely fine.
===================Updated Review============================
Thank you dev team for the new update provided. Glad to see Add-on is back in action. Deserved 5 Star rating is given back.
