Hello,
I want to use a slightly modified version of Vimperator, but I can’t install it if it’s not signed (which is quite annoying imo). So I tried to sign it with https://addons.mozilla.org/en-US/developers/addon/submit/distribution by following the instructions on https://github.com/vimperator/vimperator-labs, but it fails with “Starting with Firefox 53, new extensions on this site can only be WebExtensions”.
Is there a way I can use my version of Vimperator or do I have to use Icecat?
Thank you for your answers.
You can use Nightly, Developer or Unbranded versions of Firefox.
All developers do that too, in order to run unsigned addons.

I tried using Nightly, but Vimperator isn’t compatible with it (i think it has something to do with non-webextensions addons being disabled in future versions of firefox)
I am using Unbranded FF54 and no problem with non-webextension addons.
I hadn’t tried Unbranded, it works.
Thank you!
