Latest crash report: bp-c7581c18-335d-41c6-826e-383c40231009

Firefox blinks and then crashes when attempting to visit various websites, specifically Unsplash.com (a stock photo site) but also inconsistently on other pages including Google search results pages. I have tried refreshing, uninstalling and reinstalling, ensuring all my drivers are up to date, and disabling hardware acceleration and webGL. The only time the browser works consistently without crashing is in Troubleshoot Mode.

Chosen solution

assertion failed: self.fonts.templates.has_font(&shared_font_key) |[G0][GFX1-]: Failed sanitizing font 31 (t=1.87)

Looks like a font issue, try uninstalling fonts used by the Unsplash site:

BlinkMacSystemFont
San Francisco
Helvetica Neue
Helvetica
Ubuntu
Roboto
Noto
Segoe UI


Failing that, go to about:config and change gfx.e10s.font-list.shared to false then restart the browser.
