Hello All, For some unknown reason, the browsers available on Play Store for Nvidia Shield are crap - so far I've not found any that allow me to easily sync bookmarks etc between Shield/PC/Mobile. I therefore tested and found Opera and Vivaldi sideloaded to my Nvidia Shield TV Pro both worked perfectly. I wanted to use test Firefox as I was about to use this as my main preferred PC/mobile browser, but first I wanted to check it all worked OK. I was able to sideload and set up Firefox, but as soon as I open a webpage the Controller stopped working. How can this be fixed please? Please don't suggest a browser that's intended for AndroidTV on the Shield Play Store - they are all crap due to the reasons I mentioned, the controller with Right Joysick acting as mouse pounter works perfectly on Opera and Vivaldi, so I don't understand why this it doesn't work on Firefox. I hope this can be fixed/resolved as I would like to use Firefox as an alternative. Thanks and regards! Andrew Henshaw.
