Loading fails on Firefox if no glyphs option is passed

[ayamflow]

Happens on latest Firefox and Developer Edition too (Mac OS X) - no issues on Chrome/Safari.
I also have these errors in the CSS:

downloadable font: DSIG: table overruns end of file (<file.otf>)
downloadable font: rejected by sanitizer (<file.otf>)

Loading of a custom font was throwing an error, turns out it's from this line.

I just passed the glyphs from the example, glyphs: "\uE600\uE601\uE602\uE605" and it works.

Seems like unexpected behavior but maybe there's a reason behind this?

I tried passing stuff like \u000 outside of of the private use area and was still getting that same bug on Firefox Developer Edition and Firefox.

¯_(ツ)_/¯

I believe this is fixed now in Firefox, just tested it locally. Please reopen if you’re still having problems!
