    The “regression fix from mixedpuppy” was in fact done by me, and the “test fix from kmag” seems authored by Sebastian Hengst. Did you confuse authors with reviewers?

    Also, it wasn’t mentioned that webextensions can now set or get sidebarAction properties per window. And the analogous for browserAction is coming soon.
