All I could find was an article at http://www.omgubuntu.co.uk/2015/05/firefox-38-arrives-with-tab-based- preferences-ruby-character-support which mentions near the end:
"Improved HiDPI on Linux, with scale now set by DPI (previously defaulted to 1)". They don't really explain that and it seems to conflict with your comment that "Firefox has been set to use the system default for a long time... since Trusty was installed on this system, actually. Prior to version 38, -1 had the same effect as the 1.0 setting you suggested." Perhaps that preference was actually ignored/overridden until Firefox 38? I don't know. I don't need to adjust the layout.css.devPixelsPerPx preference on my system. When I open a command prompt and type "xdpyinfo | grep dots" I get the result "resolution: 96x96 dots per inch".
