At the moment I cant use PDF.js on Mull, based on Firefox nightly, meaning I also have about:config features.

Pdf.js is turned on in all settings, why isnt it shown? Is it even available on mobile? The annotation feature is pretty great and I think no FOSS app can do that at the moment, so really important, especially on Tablets.

Hi

If you are using a different browser than Firefox for Android, I recommend that you contact their support team for help. It is currently not possible to view .pdf files in Firefox for Android.
