In addition, the new version introduced the about:certificate page, on which users can conveniently manage web certificates. However, it turns out that this major update had a mission-critical flaw that called for quick remedial action. The folks at Mozilla responded by issuing Firefox 77.0.1 to address the bug.

Mozilla releases Firefox 77.0.1

Version 77.0.1 contains only a single fix. According to the update’s release notes, the patch turns off the automatic selection of DNS over HTTPS (DoH) providers when performing tests. DoH is a user privacy protocol that more and more tech companies are incorporating into their app solutions. So, when testing DoH on Firefox, a bug was causing something of a Distributed Denial of Service (DDoS) situation. The problem affected NextDNS, one of the companies that Mozilla brought on board to provide DoH services. The bug would cause the provider’s network to overload, preventing the wider-scale deployment of the protocol in any test run. A contributor to Mozilla’s Bugzilla forum added this about the DoH flaw: Firefox 78 is the next major browser update from Mozilla. When it hits the release channel, it should offer improvements like the ability to check out blocked web resources. Have you updated to Firefox 77 yet?
