User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.15; rv:106.0) Gecko/20100101 Firefox/106.0

Steps to reproduce:

I'm running Firefox Developer's edition 106.0b5 (64-bit) on Apple MacBook Pro (14-inch, 2021) with M1 Chip and MacOS Monterey v12.6. I was working on developing a website with WebGL rendering using 3d-force-graph (https://github.com/vasturiano/3d-force-graph).

Actual results:

• Couple of seconds later, Browser became unresponsive

• Checked Activity Monitor - noted high memory consumption (possible memory leak in my code or 3rd party library)

• Force Quit Firefox and reopened - things got even weirder

• Primary Password prompt opened and closed multiple times by itself.

• Primary Password prompt goes behind main Firefox window.

• Unable to Bring it into focus, Unable to interact with Main Firefox window either.

Expected results:

• Primary Password Prompt should stay on top of main window
• Should be able to interact with Main window with or without Primary password prompt open(??)
