Thanks to Tim Nguyen, and some groundwork laid by our excellent MSU students from last semester, we have preliminary support in today's Nightly for the ntp_background and ntp_text theme rules for WebExtensions (these rules set background and text colour for the New Tab page).

Mozilla @Firefox 62 (currently Beta, Dev Edition, and Nightly) and newer support a new TLS API for WebExtensions. I've developed what I hope a useful and comprehensive certificate viewer using those APIs, and I would love for your feedback. Thanks! addons.mozilla.org/en-US/firefox/…
