Downgrading the kernel to 5.15.0-46-generic #49-Ubuntu seems to prevent Firefox from crashing. I do not know specifically the cause.
</p><p><strong>After downgrading the host kernel, one may need to execute the command below in the host to re-install the downgraded headers to Vbox.</strong>
</p><p><strong>sudo apt install --reinstall linux-headers-$(uname -r) virtualbox-dkms dkms</strong>
</p><p><em><strong>**Please inspect the command above before using it to reinstall the headers for your particular linux distro.**</strong></em>
</p><p>Be sure to boot to the host's downgraded kernel until a fix can be completed to prevent crashes in VBox guests. Use a search engine to scout how to do this if you are unsure.

<p><strong>Updated to give a final resolve without rolling back the kernel:</strong> I Googled on the specific VB version and coupled it to the Ubuntu version above which directed me to a post that specified this particular issue. VirtualBox is claimed as the culprit for this issue. The solution is to uninstall VirtualBox 6.1.34 completely and install VirtualBox 6.1.38.
</p><p>Thanks to the users over at Ask Ubuntu for the solution!! Below is the link to the forum post.
