Problem: There is no cross browser standard for building browser extensions, which requires developers to create extensions for each browser individually.
Proposal/Mission: The Browser Extension group will attempt to standardize extension package structure, API, portability etc., across browsers.
This is a community initiative. This group was originally proposed on 2015-05-07 by Andrey Rybka. The following people supported its creation: Andrey Rybka, Gennady Slobodsky, Tao Jin, Erik Anderson, Huy Nguyen. W3C’s hosting of this group does not imply endorsement of the activities.
