Firefox not granting alarms permission

I've hit a brick wall while rewriting my extension for WebExtensions. I
need to use the alarms API, and I request permission in manifest.json, but
when I try to access the API from any of my background scripts I get errors
(because browser.alarms is undefined).

This is what I have in manifest.json:

    "permissions": [

All the permissions are granted except alarms. Does anyone know what's
going wrong? Any pointers would be appreciated.

I'm using FF 55.0.3 with web-ext to run the extension.
