Firefox quantum 57.0 (64 bit) for linux mint Linux Mint 18 64 bit Kernel 4.4.0-21 generic AMD Athlon 5370 APU with Radeon R3 x 4

On some web sites all letters disappear. This didn't happen with the previous versions of firefox. The 2 screenshots were taken two minutes ago. 1) ff01.png: xml.com 2) ff02.png: github.com.

Chosen solution

The culprit seems to be some kind of new sandboxing in 57 which prevents fonts from loading.

  • Open a new tab and type about:config in the address field (press enter, accept risks, etc., etc.)
  • Type “sandbox” in the search box
  • Change the setting security.sandbox.content.level to 2
  • Restart Firefox

If that doesn’t work you could try changing it to 1.

If this solved your problem, mark as solution.

security.sandbox.content.level was 3, now it's 2 and it works.

Many thanks.
