OS: Ubuntu 20.04 Affected Browser Versions: Latest Official Canonical packages, Mozilla Beta/Nightly apt releases, Manually downloaded tar.bz2 packages. (64bit versions 88/89) Installed Extensions: None, Clean profile

Firefox has stopped responding to pretty much anything - opening a new tab on a clean install doesn't show the suggested links/pocket articles - only a blank page (right clicking on the page doesn't open any context menu). Attempting to navigate to any `about:` pages also results in a white page. Fresh profiles exhibit the same behavior. Occasionally, executing `firefox about:config` will open the config page - but attempting to navigate to another site or about page fails. However, attempting to execute `firefox www.google.com` does not load the requested webpage.

The console also offers some warnings:
