so what happened just like the title, i cleared private data on my android device ( firefox 57.0.1, ff 58 not show up in play store yet maybe because different country) when i cleared private data i checked all option, then after that when i try to install any add on from mozilla it will said blocked add on. "Firefox prevented this site(addons.mozilla.org) from asking you to install software on your device". ill attach the picture below, the normal one(taken from long ago) and the one after cleared private data note: picture "ff" is what usually asked when i installing addon from AMO https://imgur.com/b6br847 picture "ff1" is what asked by firefox after i clear private data (checked all to clear) https://imgur.com/Ua6Vawx try to upload picture but its on endless loading. is this known bug or what? i doubt its a virus since its happening on all devices, gonna try reinstalling firefox soon Firefox 57 on Android
