Details

Description:
In some pages (like Google, as an example) Firefox stopped rendering some text; this happened since first version of Quantum (57th) version.

I tried to delete the ~/.mozilla directory and start a new config from scratch but this doesn't change things. I tried to change fonts also, but nothing changed.



Additional info:
Firefox 57.02
* config and/or log files etc.


Steps to reproduce:
Start firefox
open www.google.com.co (this page has two buttons, I'm feeling lucky and Google Search, "Buscar con Google" y "Me siento con suerte"): these two buttons doesn't render.
(application/x-gzip)    screen_capture.tar.gz (140.4 KiB)
This task depends upon

Can confirm this.

I looks like it has problems rendering any webfont, disabling them makes the site render correctly (ignoring potentially missing fonts for icons and such).
Sites I noticed this on are github.com and community.wanikani.com (which is a Discourse forum).

Installing the nightly version of Firefox fixes this issue, the "Developer Edition" is also broken.

disabling webfonts acted as a workaround, I just typed about:config and searched for gfx.downloadable_fonts.enabled and set it to false, then the pages started using the default fonts for my browser and the problem solved (partially).

Is there something to do in order to get a faster fix for this issue? Maybe reporting it to Mozilla? I don't have the experience about this.

Reducing security.sandbox.content.level to 2 should be a more effective workaround than disabling webfonts. Does this work?

I used firefox 57.0 some days without problems but suddenly it doesn't render some buttom or text at my pc too. bahn.de has other fonts and doesn't expand the details (the site will be completely greyed instead). youtube.com doesn't play html5 videos anymore. The workaround with gfx.downloadable_fonts.enabled disabled or security.sandbox.content.level 2 doesn't help for me.
Only a downgrade to firefox 56.0.2 works :-(
