Hi Mozilla, I, unfortunately, have the same problem as others regarding Firefox not blocking ads even though adblocker has been installed. I have always had the adblocker icon in the tool bar, and for each web visit, I could see how many ads being blocked. This icon has disappeard. Your soluction is to go to customize, but there are only icons for your settings (eg plugins) not the actual adblocker plugin icon. So therefore not possible to move the adblocker icon to the toolbar, as it is not showing in your customize options. I have now run a Microsoft malware/adware full scan - this did not help. I have also re-installed Firefox, and re installed several adblocker plugins. The page videnskab.dk suddenly runs ads when I access with firefox. I have just tried with Edge and no ads. So this must be an firefox browser issue. Would be great to get my icon back AND also to get the adblocker back in action. Looking forward to solution, tks, all the Best Christianne Nielsen
