Firefox seems to detect that I'm using a HiDPI display and scales automatically, I really want to disable this so GNOME can handle the window scaling. I can't find the way. BTW changing the "layout.css.dpi" about:config makes no difference.

I'm using:

  • FF Quantum
  • GNOME 3.26.2
  • Ubuntu 17.10

Cheers

Does it work if you set layout.css.devPixelsPerPx in about:config to 1.0?

Like I mention in my original posting that makes no difference.

Just to be clear, you've tried both "layout.css.dpi" (which is what you mentioned in your original post) and "layout.css.devPixelsPerPx", and neither one worked? Because they're different settings.
