Hi all, I'm new to the forum. I've tried to search for my issue but I find only something from 2015 and 2016 and it is not for the android version of Firefox. Basically on my Tab S 8.4 marshmallow if I try to tap the 3 bullets button to access the menu nothing appens. Same story if I try accessing the menu long pressing the recents button on my device. The issue happens with no extension installed and with my regular extensions installed, both logged in in my Firefox account and not logged in. I've noticed, though I cannot quantify, that when Firefox is installed the general usage of my device feels more laggy and it takes longer to load pages in chrome. So far I've tried: deleting data, reinstalling the app, factory reset. On my phone I do not have this problem. (though is a completely different device with a different version of android). Thanks a lot for helping fixing my problem.
