I was trying to find a roadmap for Firefox Preview, I have supported mozilla since the first realease of Firefox and like this Preview version and as I understand Firefox currently has a low market share, but if you want to change that on the android or mobile phone market as a whole, then you really need to get the essentials into preview asap especially plugins, a lot of users rely on plugins for a variety of things myself I use plugins to enforce safe search since this feature is not built-in to Firefox although I think it shoud be and so because of the lack of plugin support preview is of no use to me atmm Also all users of preview are kept in the dark about up and coming features and I strongly recommend create a roadmap with a timeline of what features are scheduled to be implemented and a target date, otherwise you are going to lose many potential users. You could put a link to the roadmap on the app in Google Play.
