Stylus stopped working on sites like Facebook and Instagram on Firefox Android

I notice that font replacement script stopped working on Firefox Android after Stylus is updated to latest version.

What is "font replacement script"? How can I reproduce the problem?

[asf383]

Sorry I forgot to attach the script. Please check the attachment "stylus_script.txt". However, I use a font file hosted on my own AWS S3 and I removed the FQDN. If you want my URL, please let me know I can share with you via PM.

Also I found that the same issue happens also on Firefox Desktop (Windows).

Sounds like Patch CSP is disabled in the options.

Anyway, with a public google font it works for me in Firefox even without enabling this option.

[asf383]

It is enabled.

Tried setting the options just like that, a google font still works for me.

It seems that the part not working is the loading of remote font. I replaced it with a local one on Windows and it worked.

The remote font was working in the previous version of Stylus.

Pressed the wrong button and closed it accidentally. Reopening it.

I managed to find a console error with 2.3.18. Sent you the URL also.

That error is unrelated, but there was an error in tab's console and turns out PatchCSP option was broken in 2.3.18, so I've reverted it in AMO to 2.3.17 re-published as 2.3.19. If you want to keep testing the broken version, you can disable extension auto-update in about:addons.
