Operating system : Windows 10 1809 LTSC
Browser version: 33.9.0.1
32-bit or 64-bit browser?: 32-bit
Problem URL: https://code.videolan.org/videolan/npap ... 15a9a14abe
Browser theme (if not default):
Installed add-ons:
Installed plugins: (about:plugins):

If possible, please include the output of help->troubleshooting information (as text):

Code: Select all

Faulting module name: fontdrvhost.exe, version: 10.0.17763.1757, time stamp: 0x32f7786a
Exception code: 0xc0000005
Fault offset: 0x000000000008c0c3
Faulting process id: 0x58
Faulting application start time: 0x01dc3d2c87d14c88

Faulting application name: palemoon.exe, version: 6.8.0.9398, time stamp: 0x68d3b221
Faulting module name: mozglue.dll, version: 6.8.0.9398, time stamp: 0x68d3b216
Exception code: 0x80000003

Faulting application start time: 0x01dc3d7dd5c71e00
Faulting application path: C:\Pale Moon\palemoon.exe

And because it crashes fontdrvhost, the only solution (except OS restart) is taskkill /im dwm.exe /f /t

I have direct2d disabled (gfx.direct2d.disabled;true), when hardware acceleration is enabled, maybe it affects that too?

That URL was opened as new tab (in background).

Seems to be similar one indeed. Will try setting gfx.content.azure.backends to skia,cairo

But I thought, simply disabling direct2d should disable it everywhere, so it is not?

It does disable it everywhere. But this Windows font bug is obviously not in Direct2D.
