This bug was filed from the Socorro interface and is report bp-c5522888-e1a4-4903-abbb-3c59f2130120 . ============================================================= Reporting this for the person who posted the linked thread on MozillaZine. I'll try to get the Graphics section from about:support. Apparently 18.0.1 is instantly crashing whenever acceleration is enabled.

Okay, here's the graphics section of about:support, with acceleration disabled: Adapter Description ATI Radeon HD 4300/4500 Series Adapter Drivers aticfx64 aticfx64 aticfx32 aticfx32 atiumd64 atidxx64 atiumdag atidxx32 atiumdva atiumd6a atitmm64 Adapter RAM 512 ClearType Parameters Gamma: 2200 Pixel Structure: RGB ClearType Level: 100 Enhanced Contrast: 400 Device ID0x954f Direct2D Enabled no information DirectWrite Enabled false (6.1.7601.17789) Driver Date 7-3-2012 Driver Version 8.970.100.3000 GPU #2 Active false GPU Accelerated Windows 0/1 Basic no information Vendor ID0x1002 WebGL RendererGoogle Inc. -- ANGLE (ATI Radeon HD 4300/4500 Series) AzureCanvasBackend cairo AzureContentBackend none AzureFallbackCanvasBackend none

It's Catalyst 12.6, the latest one for ATI Radeon HD 4300/4500 Series (legacy). He is the only one to hit this crash signature (https://crash-stats.mozilla.com/report/list?signature=atidxx32.dll%400x1b95b7) so no need to add a graphics blocklist, the Safe Mode prompt following a startup crash is enough.

Closing as incomplete since we have no recent data to go on. Please reopen this bug report if the issue still reproduces.
