- Other minor tweaks, fixes, and refinements.
Desktop-only
- LINUX: Disabled Geoclue by default (to reduce our reliance on OS-provided/external services, in favor of the browser's built-in network geolocation provider).
- non-OS X: Explicitly enabled the network geolocation provider by default, to ensure that it's properly enabled, instead of just relying on the fall-back/testing provider.
- Added DNSBunker and
dnsforge.deto the list of built-in DNS over HTTPS providers. - Disabled fetching GMP plug-ins from Chromium servers (if GMP is enabled) to prevent additional unnecessary connections to Mozilla.
- Disabled the Remote Settings-backed new tab renderer.

- This also fixes an issue that caused favicons to not display properly on
- Disabled reliance on OS location services/system permission for geolocation, so that the network geolocation provider can always fall-back/work properly as expected.
- Prevented the browser from automatically downloading tab group AI models (if the relevant functionality is enabled).
