Hello Here are some ways to troubleshoot it : '''Use Firefox Troubleshoot Mode: ''' Hold down the Shift key on your keyboard and click your Firefox shortcut. Select "Open" in the dialog box. If it works, an extension is likely causing the crash. '''Rename Profile (Force Reset): ''' If Firefox won't open at all, rename your profile folder to OldFirefox in %APPDATA%\Mozilla\Firefox\Profiles\ to force Firefox to create a new, clean profile. '''Disable Hardware Acceleration: ''' If you can reach the menu briefly, go to Settings > General, scroll down to Performance, uncheck "Use recommended performance settings," and uncheck "Use hardware acceleration when available." '''Update Graphics Drivers: ''' Ensure your GPU drivers are updated, as faulty drivers often cause browser crashes.
