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.

Vimperator @ Firefox 47

When I started Firefox 47, configurations of views in .vimperatorrc were not reflected.

I could use such o command and open a site, but there was no complement, and it showed Application is not defined.

This is because Vimperator depends on FUEL library, which was removed at Firefox 47.

Developers of Vimperator build new version for Firefox 47, and released new version in GitHub just a short while ago.

Release Vimperator 3.14.0 · vimperator/vimperator-labs

To install it, first you need to disable a signature check. Open about:config and search xpinstall.signatures.required, then make the value to false.

Then, download vimperator-3.14.0.xpi, drop it to Firefox.

If you try to click the xpi link directly, Firefox rejects to install from these sites directly, so that you need to download first.

It seems it takes a time to release it in Firefox’s Add-ons page, therefore you need to install GitHub version if you need Vimperator with Firefox 47.

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.
