Font rendering in Nightly 68


(Core :: CSS Parsing and Computation, defect)

Not set





(Reporter: koutris, Unassigned)


(Keywords: regression)

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:66.0) Gecko/20100101 Firefox/66.0

Steps to reproduce:

Nothing in particular. Just did my daily nightly upgrade.

Actual results:

The fonts in various sites changed from Arial to something else. Verdana or Tahoma. The rendering is now similar to Google Chrome. Sites affected are,, I use the same settings from Netscape era and I never change them.

Expected results:

Firefox should respect my font settings to Arial 14. Instead it has changed to something else.

Component: Untriaged → CSS Parsing and Computation
Product: Firefox → Core

Can you go to about:config, search for font, and copy all the pref values that are there? In particular, is browser.display.use_document_fonts set to something different than 1?

Tagging as a regression for now, but I think this is going to be bug 1536718.
