Festive Greetings Mozilla Company and I hope that you are developing for the future. I mentioned this idea in Google Playstore as part suggestions part opinion and got a response, FROM MOZILLA, and a link to say that here so it's about the Mozilla Firefox Browser having a fully Web Developer friendly features such as :
1.Dhtml , Shtml ,Html ,Html5
2.Css , Css2 , Css3 or Css4 etc...
3.Javascript encyclopedia of libraries to add and choose from e.g. Json, React , jQuery ,Ajax or Phaser
4. Php MyAdmin with Zend Engine ( Sqllite, Sql , MySql )
to allow offline developments on the developers device as a virtual server as to allow for offline developments of the web.
This would then enable Web Developers to further Develop how they can with the, Mozilla Firefox Web developer browser and once it's prototypical , I suggest that Mozilla would broadcast on all Socials so people like me can get to explore it and reciprocate communication about it here and there
