mozilla/web-ext 2.3.0 on GitHub

Running an extension in Firefox for Android is now supported via --target=firefox-android (#868) (1b22d60)
You can now set option defaults in a configuration file using --config (#1080, #1152). Several other patches from @shubheksha had already landed to make this feature possible.
A config file named web-ext-config.js in the current directory or one named .web-ext-config.js in the user's home directory will be loaded automatically (#1161)
