Fix blurry firefox under wayland

2025-01-12

I have an HDPI screen with fractional scaling of 1.5, and firefox was blurry under wayland sway.

I tried all combinaison of environment variable but it was either zoomed in too much or still blurry.

I finally found the culprit, which is a firefox setting.

In about:config change the following setting:

widget.wayland.fractional-scale.enabled must be set to true
