User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:58.0) Gecko/20100101 Firefox/58.0 Build ID: 20180130084414 Steps to reproduce: I'm using firefox with arch linux and dwm. I can adjust layout.css.devPixelsPerPx to 2 if I use a hidpi display. Actual results: The font size in bookmarks and address bar and dropdown menu does not get scaled, only the content of web pages does. Expected results: The font in bookmarks and address bar and dropdown menu should get scaled appropriately.

Indeed it is GTK+ 3 related: setting export GDK_SCALE=2 almost solves the issue (still the icons remain small, while e.g. in Chromium they scale nicely), but all the rest is fine.
Actually, I stand corrected: notwithstanding the above export, one still needs to change the parameter in about:config by hand to get the text in web pages in the correctly dimension. This is very painful to do every time one switches monitor; consider Chromum does that automatically once the export above is set.
If I also set that variable to -1 it automatically handles everything, so it is not a bug, just my ignorance.
