You can try safe mode - to see if an addon or plugin is conflicting. If it doesn't help, the next fastest thing is uninstall Fx.

If it crashes & didn't before, easiest thing is to uninstall Fx completely from Control Panel, remove any remaining files, reboot.

Shut down everything - incl. AV / FW. Disconnect from web. Then reinstall.

If you have submitted crash reports then please post the IDs of one or more recent crash reports that have a "bp-" prefix:

• bp-xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx

You can find the IDs of the submitted crash reports on the about:crashes page.

• You can open the about:crashes page via the location bar, like you open a website, or open the crash reports page via "Help > Troubleshooting Information".
