Is there a service for developing add-ons for the most popular browsers?

Question

Browser extensions

Hello. There is a need for your own product to create a plug-in for time tracking, which would work as a kind of standard extension with REST support and several basic pages.
Tell me, please, is there any platform that allows you to assemble a ready-to-publish plugin for most browsers from js, css and html?
Preferably Chrome, Mozilla, Safari, IE.
I wanted to develop a mobile application (ios / android) and plugins for popular browsers in the same style. To do this, for example, you can take ionic / cordova, make an application based on it, and shove www stuffing into a certain combine that converts it into extensions for major browsers with minor modifications.
As you know, there are some combines, like Kony, that make both applications and extensions, but they are paid on an ongoing basis.
Thanks for answers.
