You can easily check if xdyinfo is correct by dividing your screen dimensions (in pixels) by their actual physical value (in inches). If you find significantly different values from xdpyinfo, x is wrong and you need to open a bug to get it fixed (@rh is you use FLOSS gfx drivers, @someone else otherwise). If xdpyinfo is right that's a pure firefox problem. Two possibilities: 1. you've been lying to firefox about your dpi all along to get small fonts → now that autodetection is working the correct fix is to change the default font sizes (in pixels) in firefox (and vote/comment for https://bugzilla.mozilla.org/show_bug.cgi?id=414427 so you don't have to enter font sizes in two places with two different units in the future). I guess the ultimate test would be to create a page with font sizes specified in inches or millimeters, and then check than when it's rendered by firefox the physical sizes are right. 2. something else is broken → open a firefox bug As others wrote the dpi situation is in a lot of flux right now. Not because someone broke something but because our previous handling was massively wrong (with various apps abusing dpi or even hardcoding it to fixed values, and downstream apps adding bandaids over bandaids to compensate), so fixing it involves changing apps behaviour and replacing font defaults when they've been set up for false scaling factors values. Also the Xorg people underestimated the importance of getting xdpi computation right when the latest xrandr landed, so many xrandrified drivers still get this wrong. -- Nicolas Mailhot
