Im working on an addon which injects an html element into the webpage and in that element that I inject I want to include some font that I have stored locally in the ‘data/fonts’ folder. Unfortunately I get this error
downloadable font: download not allowed (font-family: "Avenir LT W01_35 Light1475496" style:normal weight:normal stretch:normal src index:0): bad URI or cross-site access not allowed source: resource://gt-firefox/data/fonts/Avenir-light.ttf
Does anyone have any idea how I can get the fonts to work?

This solution uses low level components not available to SDK I think. So you will need to use require('chrome')
I had a project where I hit this as well, but it was for Twitter. I used evalInSandbox -

his topic links an article to MDN which gives the code that worked exactly for me on Twitter - http://www.stackoverflow.com/a/32495180/1828637
It likes to MDN here - https://developer.mozilla.org/en-US/docs/Mozilla/Tech/XPCOM/Language_Bindings/Components.utils.Sandbox#Example
Once inside the sandbox, try importing the resource. If it doesn’t work, make binary data out of and make a blob from within the sandbox, that way it shouldn’t see it as remote.
You sir are awesome!

Woohoo! So glad it worked. You’re awesome for actually taking the pointers and trying it all out, excellent job!
