All Tabs Continue to Crash After Multiple Troubleshooting Attempts

Hello,

Since starting Firefox up today, every single attempted open link or tab crashes. A new, blank tab will crash, and even some about:tabs crash and must be attempted a few times to access. After going through multiple troubleshooting guides from both Mozilla and from users, I'm at a complete loss. A list of things I've tried:

-Restoring crashed tabs -Restarting Firefox -Restarting Firefox in Safe Mode -Clearing Cookies & Cache -Removing all addons and plugins -Restarting PC -Reinstalling Firefox -"Refreshing" Firefox -Making a new account -Restarting Firefox in Safe Mode after reinstall/refresh/new account -Checking browser internals -Troubleshooting/Reinstalling Flash -Checking for security software/malware issues -Switching browser.tabs.remote.autostart to false -Switching media.wmf.vp8.enabled to false -Checking that drivers are up to date -Switching to an older version of Firefox -Making a new profile for an older version of Firefox -Re-reverting to the current version of Firefox -Restarting PC another time and trying these again

Despite all of this, all tabs save for the about:tabs (excluding about:blank) crash immediately. I have no idea what else I can try, and any assistance would be appreciated.

We have seen multiple reports that Bitdefender is causing this issue. If you use Bitdefender then try to uninstall this software.

You can try to contact Bitdefender for support.

EDIT: I noticed that a bug report is filed:

  • Bug 1616993 - Reports of tab crashes caused by Bitdefender

First attempt didn't work. Checked again, Bitdefender Agent was still installed. After uninstalling both Bitdefender products, Firefox works perfectly. Thank you ♥
