Prevent Firefox from inheriting system font size

submitted by u/nuwanda_nova to r/social

I’ve recently changed my Windows 7 system font size to 110%.

I notice Chrome and IE don’t apply the system size, and continue to display the base font at 16px, the browser default. This is the way I prefer it for development.

But Firefox (and Dev edition) apply the system font size to the base size for all text. Consequently the pages render at 110% of the actual font size setting.

Is there a setting I can use to force Firefox to use 16px or to prevent it inheriting the system font size?

Setting layout.css.devPixelsPerPx to 1.0 should give you what you want.
