Yesterday, Mozilla released Firefox 47.
Unfortunately, current version of Vimperator doesn’t work with Firefox 47.
Firefox 47 has several updates for Videos, such embedded YouTube videos can be played with HTML5 video if Flash is not installed.
Another update is for the synchronization, that you can view/search open tabs from other machines.
In addition, there are some changes related to addons, and there seems some addons don’t have compatibility.

On the other hand, this
xpinstall.signatures.required option will be
removed at Firefox 48.
I think new Vimperator will be released in Firefox’s Add-ons page soon, but we should be careful about these releases.
