I've had this Shopback Firefox extension now for a couple of years. When I'm on a page that I can get Shopback Rewards such as AliExpress I will need to remember to click on the Shopback button to activate it, no login, just click, it then turns green an you're ready to shop. You do need to be careful as sometimes when you go to shopping cart it will open in a new window, so you need to check that the Shopback button menu in the menu bar is still green, it usually is though sometimes it will turn to orange(off) again so then you need to re-click the Shopback button then wait for it to turn green again before you make your purchase. Other than this little frustrating issue (which I don't think is by Shopback's design) then this is a very useful and profitable little button, 5 stars form me⭐⭐⭐⭐⭐
