Sorry to hear that your Firefox is crashing. To help us understand the issue, we need some more data from you. When Firefox crashes, it usually records information about what was happening at that moment and shows you the Crash Reporter. You can submit that data to Mozilla and share it with forum volunteers to see whether it points to the solution. Please check the last section of this support article "[[Firefox Crashes]]" for steps to get those crash report IDs, and then post some of the recent ones here. If that's not possible because Firefox crashes too quickly, have you tried Firefox's Safe Mode? That's a standard diagnostic tool to deactivate extensions and some advanced features of Firefox. More info: [[Troubleshoot Firefox issues using Safe Mode]]. You can restart Firefox in Safe Mode using either: * "3-bar" menu button > "?" button > Restart with Add-ons Disabled * Help menu > Restart with Add-ons Disabled Not all add-ons are disabled: Flash and other plugins still run After Firefox shuts down, a small dialog should appear. Click "Start in Safe Mode" (''not'' Reset). Any difference?
