You can try to disable hardware acceleration in Firefox.

• Tools > Options > Advanced > General > Browsing: "Use hardware acceleration when available"

You need to close and restart Firefox after toggling this setting.

You can check if there is an update for your graphics display driver and check for hardware acceleration related issues.

Firefox has consistently crashed on closing for more than two weeks. I went through all of the trouble shooting steps and it continues to happen (including refreshing, "safe mode", checking add ons, etc.) Please help. Here are the last group of crash reports: bp-dffd6541-51b4-4e99-bbcb-8fd4a2150823 8/23/2015 6:32 PM bp-09923bb0-6bf9-4f0f-a6fa-f23172150823 8/23/2015 6:32 PM bp-5a2b8534-5ad0-4bdf-b3e9-039392150823 8/23/2015 11:54 AM bp-18c4ac12-a650-4270-a253-a15012150823 8/23/2015 10:13 AM bp-4016b3c1-aa4f-4234-8bad-805722150822 8/22/2015 8:08 AM bp-f3997ec5-f94f-404d-8fd9-0ca042150822 8/22/2015 8:06 AM bp-45b499a0-4e50-46a2-befc-14b542150822

Thank you, Cor-el. Disabling hardware acceleration solved this. My NVIDIA driver was up to date though. Thank you for your help! I am grateful.
