1460821 - font-face mixed http https stops fonts rendering

Status: UNCONFIRMED

(Core :: Graphics: Text, defect, P3)

Description

Attachment: 30-days-fonts-2018-font-bug.zip

User Agent: Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/66.0.3359.139 Safari/537.36

Steps to reproduce:

visited https://e-activist.com/page/23394/action/1


Actual results:

Virtually blank page because of not being able to load some fonts that are defining a font-face. It was immediately obvious something was wrong & fonts were missing. There were mixed-content warnings. Fallback was supplied.


Expected results:

Fallback font to be triggered because the webfont had loading issues (and therefore should be unavailable, not available with no glyphs)

Thank you for the report. Please test if this makes a difference:

1. Enter the following into the address bar
about:config?filter=security.sandbox.content.level

2. Click the big button to bypass the warning.

3. Double-click the security.sandbox.content.level preference and set it to 1

4. Exit, then restart Firefox.

5. Try the page again. Is the text visible?

Works for me. Quite a few things blocked because of mixed content and CORS though.

Hello,

That setting (1, close all firefox windows, load check setting is one after restart, load url) does not affect the rendering of text in nightly or stable.

I'll try in windows later see what firefox on windows and what IE + Edge do.
