Today, Firefox on macOS, and Firefox in a Parallels VM (Windows 10) are unable to open any websites outside my local network(e.g. 192.168.1.1). Other browsers are work correctly, and even "curl" works correctly. Checked all settings, reinstalled Firefox, refreshed Firefox, re-read all Mozilla docs on this issue. Doesn't appear to be affected by Firefox setting "DNS prefetch". Mac is running Sequioa 15.0 Firefox versions: macOS 130.0.1 (64-bit), Windows 10 (within Parallels for Mac): 125.0.3 (64-bit) Firewall is set to prevent incoming connections to Firefox and Google Chrome (set by company profile).

Thanks in advance for any insight.
