Ask HN: Firefox connection problems after enabling DoH?

Article summary

The latest version of Firefox has a problem where enabling DNS over HTTPS (DoH) causes the browser to be unable to establish connections. Disabling DoH does not resolve the issue, and closing the browser leaves processes running in the background. Several users have reported this issue across different versions of Firefox on Windows and Linux. A potential workaround has been found by disabling HTTP3 support in the browser's settings.

What commenters say

• Disabling HTTP3 support in Firefox's settings resolves the connection issue caused by enabling DoH.
• Automatic updates can cause problems when they introduce new features or bugs without user consent.
• Some users prefer to have control over when updates are installed, rather than having them applied automatically.
• Separating security updates from feature updates could be a better approach than the current automatic update system.
• The default setting of automatic updates is convenient for most users, but can be problematic for those who value control over their environment.
• Disabling automatic updates altogether may not be a viable solution due to the importance of staying up-to-date with security patches.
• Users should be given the option to choose their update policy, rather than having it imposed on them by the software manufacturer.
