lately the html5 video player controlls are gone until you once disable the addon , play a video and then enable it again.

great! any known addons it breaks ?This review is for a previous version of the add-on (0.1.0).
It will only break some of the add-ons that load their own files into Web pages. It should be compatible with uBlock Origin and HTTPS Everywhere for example.
