impossible to use even though signed in to Premiumize.me account!!!! Click on add-on icon - it shows "you are not logged in" -- click on "login" and it just opens Premiumize.me web site where I am already logged in - OVER & OVER & OVER AD-INFINITUM! Complete waste of time. Just Pure Crap!

Thank you, thank you, thank you! So glad to see this addon up and running again after FF 71 seemed to break almost all the proxy addons. I tried a few replacements, but none worked as smoothly and dependably as Premiumize. I use it several times a day, so I really missed it those few weeks.
