I can’t believe there is no web console yet for Android, directly and without adb, Remote debugging or sth. As sample while I want to run a simple JS code from console, what shall I do?!
We try to keep the size of Firefox for Android as small as possible so that it can be used on many different Android devices all over the world.
Adding developer tools to Firefox for Android would make the app size much bigger and may only be useful to a small number of people.
We do keep the features of Firefox for Android under review and this may feature in a future update. Alternatively you may want to look for a suitable add-on that may provide the functionality you are looking for.
Thanks, but at least give me a clue, like a magic word to search the add-ons?
A good place to file this as feature request is also https://github.com/mozilla-mobile/fenix , where development of the new mobile browser happens.
