According to your system info, you have dmi.chassis.type: 10, which is a
notebook.  What brand and model of notebook is it?

Try adjusting Firefox's setting for High DPI support, which operates as
a global zoom factor:

(1) In a new tab, type or paste about:config in the address bar and
press Enter. Click the button promising to be careful.

(2) In the filter box, type or paste pix and pause while the list is
filtered

(3) The layout.css.devPixelsPerPx preference usually is set to -1.0
which means use the system default. You can change that to 1.0 for
96-dpi dispay and see whether that is what you prefer. And you can
increase the size from there in increments, for example, 1.1 for a
global "110%" zoom.

Please be careful not to set this value to something tiny, as it can be
hard to recover from that.

Title:
  Firefox appears horribly distorted after upgrade to 38.0

Status in firefox package in Ubuntu:
  New

Bug description:
  Today when I opened my package manager (muon) to check for updates, I
  saw there was an update for Firefox, to version 38. I installed this
  along with other available updates like I always do. Upon restarting
  Firefox, however, I discovered a nasty surprise. All of Firefox's UI
  was appearing as if I was on a computer with a much lower screen
  resolution, and web pages were appearing as if I had massively zoomed
  in on them.

  Everything looks many times bigger than it should be: icons, toolbars,
  tabs, menus, web pages, they're all big.

  I have no idea how or why this happened.

  I tried restarting Firefox in safe mode, wondering if it was maybe an
  incompatible add-on. This did absolutely nothing for me. I began to
  suspect that the update to Firefox 38 had caused the problem. So I
  decided to test my theory by downgrading. The only prior version in
  the repos appeared to be 28.x, but luckily, in my
  /var/cache/apt/archives/ folder, I found the .deb for the last version
  of Firefox I had installed - 37.0.2. I opened the .deb and installed
  it. Upon opening Firefox, everything was normal again -no abnormally
  large chrome or web pages.

  I ran the upgrade to Firefox 38 again, and bingo - the problem came
  back. I ran ubuntu-bug firefox to get Apport going, and then finished
  up by coming here to Launchpad to submit a report. Attached a
  screenshot to show the distortion.

  My computer's native resolution is 1920x1080, and that's what I run.

  I'll have to stick with 37.0.2 until I get some confirmation that this
  issue with Firefox 38 has been addressed/resolved. Firefox is unusable
  with this problem.
