Thank you! One question,Can it support on Firefox57++?

This review is for a previous version of the add-on (26.0.0.151).

Fx57+ will probably ignore old-style addons. I still have no idea if new addon format is suitable for distributing binaries and placing them to plugin directory.
Will research later.
