Created attachment 821030 [details] font-pdfjs.png Font rendering done by Mozilla's internal PDF viewer (pdf.js) is sometimes ugly. Note that the status of "Allow pages to choose their own fonts..." doesn't matter. This is *not* bug 738627 (which is fixed in this version, BTW). For instance, the problem can be seen on: http://www.dgdr.cnrs.fr/achats/agence/fichiers/Bonnes%20pratiques-Marche-Voyages-hebergement.pdf I've attached a part of a screenshot on page 3, obtained with Iceweasel 24 (Debian/unstable). But the same problem occurs with Nightly 27.0a1 (2013-10-23). External PDF viewers Evince and xpdf do not have any problem on this PDF file.

Mozilla/5.0 (X11; Linux x86_64; rv:27.0) Gecko/20100101 Firefox/27.0 I couldn't reproduce the issue on latest Aurora (20131118004001). Do you have hardware acceleration enabled? Thank you
Here's what about:support gives me for Graphics: Adapter Description nouveau -- Gallium 0.4 on NV98 Device ID Gallium 0.4 on NV98 Driver Version 3.0 Mesa 9.2.2 GPU Accelerated Windows 0/1 Basic Vendor ID nouveau WebGL Renderer nouveau -- Gallium 0.4 on NV98 windowLayerManagerRemote false AzureCanvasBackend cairo AzureContentBackend none AzureFallbackCanvasBackend none (I'm currently using Debian's Iceweasel 24.1.0, where I can reproduce the bug.)
Also reproduced using Firefox 25 on WinXP with HWA disabled (blocked due to driver version). Looks like the font selection is incorrect, so the (wrong) selected font is stretched badly.

Reproduced with the latest PDF.js add-on (0.8.713).
I have the same problem on FF 25.0.1 viewing the same pdf on two Windows 7 x64 systems. The older system has a Radeon X600 graphics card with the Microsoft-supplied drivers, and has an ugly display. The other uses the internal Intel HD graphics on the i3-2100 CPU and is fine. gfx.direct2d.disabled is false on both FF's.
The same on FF esr 24.2.0 with Win XP et 7. It's ok with Chrome or FF+Acrobat Reader. I just understand that this new feature is buggy at first but why change the pdf reader by default during installation of FF 24??
The same with Firefox Nightly (firefox-29.0a1.en-US.win32.installer.exe)

Thomas, on latest Firefox versions, this pref is set by default (see Options -> Applications: Portable Document Format (PDF) - Preview in Firefox) and can be changed.
