Loading the vimeo site on nightly and rapidly switching back and forth between full screen produces this crash consistently for me using Flash .268 1. Load Vimeo 2. Use context menu to switch into full screen 3. Mouse click in Flash content area and switch back and forth. 4. After about 4 times it crashes consistently. https://crash-stats.mozilla.com/report/index/bp-ff469da3-623e-42bd-9ea2-5f8c32120725 https://crash-stats.mozilla.com/report/index/bp-08180ad5-7dd7-4c0e-a0ff-d057c2120725 Windows Vista machine, 32 bit OS, 2 GB RAM, 2.80 GHz Graphics Adapter Description NVIDIA GeForce 8800 GTX Vendor ID 0x10de Device ID 0x0191 Adapter RAM 768 Adapter Drivers nvd3dum nvwgf2um,nvwgf2um Driver Version 8.17.13.142 Driver Date 5-15-2012 Direct2D Enabled true DirectWrite Enabled true (7.0.6002.18592) ClearType Parameters ClearType parameters not found WebGL Renderer Google Inc. -- ANGLE (NVIDIA GeForce 8800 GTX) -- OpenGL ES 2.0 (ANGLE 1.0.0.1041) GPU Accelerated Windows 1/1 Direct3D 10 AzureBackend direct2d

This showed up on the explosive report - https://crash-analysis.mozilla.com/rkaiser/2012-07-29/2012-07-29.firefox.15.explosiveness.html and it still occurring with .268.

Thanks. It would be helpful to know whether or not the crash occurs with protected mode disabled, and/or if it occurs with Hardware Acceleration disabled. In the meantime, I'm trying to track down a similar configuration to repro on.
