Your first three crashes are associated with a graphics problem. If you haven't already tried this, start Firefox in its Safe Mode and disable Firefox's use of hardware graphics acceleration. (1) Firefox's Safe Mode is a standard diagnostic tool to bypass interference by extensions (and some custom settings). More info: [[Troubleshoot Firefox issues using Safe Mode]]. If Firefox is running: Help > Restart with Add-ons Disabled If Firefox is not running: Hold the Shift key while start Firefox Then, in the dialog, click "Start in Safe Mode" (''not'' Reset) (2) The hardware acceleration feature is sensitive to graphics driver incompatibilities. Disable it here: orange Firefox button (or Tools menu) > Options > Advanced On the "General" mini-tab, uncheck the box for "Use hardware acceleration when available" Then exit and restart Firefox. Any improvement?
