I am developing an app for panasonic smart tv with firefox OS 2.5 , i cannot find a simulator for firefox OS 2.5, also when i install firefox os for tv 2.6 unstable version it crashes very often, this is also limited to the firefox browser version, it can be installed on version 54.0 or less firefox browser. Can i know what are my option to simulate panasonic smart tv with firefox os 2.5 without the device ? I tried with mulet but that does not seem to work ? can you let me know the option to simulate the device ?
