Ask HN: Firefox connection problems after enabling DoH?
594 by killdozer | 338 comments on Hacker News.
The latest version of Firefox (96.0 and 95.02) seems to have a problem where as soon as you enable DOH (DNS over HTTPS) the browser is unable to establish any connections. Disabling this feature once enabled doesn't resolve the issue, closing the browser leaves processes hanging in the background consuming resources. Several of my friends have reported (Windows/Linux) seeing the same issue but we haven't been able to find a solution.
