How can I stop crashing tabs on Firefox?

Hi Thom, sorry to hear the tabs keep crashing — a few details would help narrow this down: does it happen on particular sites, or on any tab, and did it start after an update or after adding an extension? In the meantime, these steps usually help to isolate the cause: 1. Restart Firefox, then try with your extensions temporarily disabled — if the crashes stop, re-enable them one at a time to find the culprit. 2. Try Troubleshoot Mode from the Help menu, which starts Firefox with extensions and some custom settings turned off, to see whether the crashes still happen. 3. Make sure Firefox and Windows are fully up to date, and check whether any security or cleanup software is interfering with Firefox. 4. If a particular tab always crashes, note what is open in it, so the pattern is clearer. Let us know what you find, especially whether Troubleshoot Mode makes a difference, and we can take it from there.
