It's an off topic, but if someone is in know of these things, please help. I am using firefox Marionette framework for automation of several routine interactions with websites. Marionette used to work on firefox on android as well. After some recent upgrades it seems marionette port 2828 is not being listened to by firefox.
Firstly there are 4 different firefox versions on Android play store. 'Firefox' 'Lite' 'Beta' and 'Nightly'. 'Firefox' and 'Lite' do not provide about:config interface to check the settings. 'Nightly' and 'Beta' allow that but enabling marionette there isn't really enabling it i.e. on port 2828 where it's supposed to listen the connection is refused, if I test with telnet. Web searches on this topic almost lead nowhere indicating probably there aren't takers for marionette on android. -- Mayuresh
