How do I fix incorrect resolution for Firefox user interface on Retina display Mac?

I have a 15" retina display Mac (roughly a year old) running Mountain Lion. A couple weeks ago the user interface in Firefox seems have switched from using the normal zoom level of every other application to the native dpi of the retina display monitor. This means that the UI elements are all extremely tiny, etc. Is there anyway to reset this without simply reinstalling or reseting the rest of my configuration?

Currently running Firefox 27.0.

Here's a screenshot to clarify the question. You can see how the UI of Firefox is tiny in comparison to the Chrome browser running in the background.

You can try to modify the gfx.hidpi.enabled pref on the about:config page (<=0: disable; 1:all screens same res; >1:enable always).

Try to disable hardware acceleration in Firefox (you need to close and restart Firefox).


You can set the layout.css.devPixelsPerPx pref on the about:config page to 1.0 and if necessary adjust layout.css.devPixelsPerPx starting from 1.0 in 0.1 or 0.05 steps (1.1 or 0.9) to make icons show correctly.

You can look at this extension to adjust the font size for the user interface.

You can look at the Default FullZoom Level or NoScript extension if web pages need to be adjusted after changing layout.css.devPixelsPerPx.
