Most Crashes (not all) are from below problems....... See if you can find updates for your Intel(R) HD Graphics as they are unknown yrs old :driverDate: 7-19-2011 You can Google Intel(R) HD Graphics and find the download page https://downloadcenter.intel.com/product/80939/Graphics-Drivers, but you may have to know what generation chipset you are using. CPU-Z would tell you this https://www.cpuid.com/ Can also try : https://www.intel.com/content/www/us/en/support/detect.html I see several errors in the drivers. Old & corrupted Drivers cause a wide range of issues. Please keep them updated to prevent issues and you never know when Intel will stop supporting them. This far out of date a new card is warranted You could try this please : Go the Menu then Tools --> Options --> Performance and untick everything. change the recommended size lower then see how it runs. Note: 0 = No Multi-processor = slow again. TRY 2 Restart Firefox after making these changes please. If still need to if above does not work : Please Submit your bp- files as a URL directions to do so please follow : https://support.mozilla.org/en-US/kb/firefox-crashes-asking-support Send last 2 only. Please let us know if this solved your issue or if need further assistance.
