Mozilla plans to release Firefox 77.0.1 to the Stable channel later today. The new version of the web browser comes just a day after the release of Firefox 77.0 Stable on June 2, 2020.
While it is not uncommon for Mozilla to release a smaller update shortly after a major version update, the time between a major release and a bug fix release is usually a good indicator of the importance of the update.
The release notes list a single bug:
Disabled automatic selection of DNS over HTTPS providers during a test to enable wider deployment in a more controlled way
The linked bug, 1642723, provides additional insight on the fix. According to its assignee and other contributors, the fix "prefs-off a feature" related to Firefox's rollout of DNS over HTTPS that caused network strain on the network of the provider NextDNS.
We need to be able to roll this out gradually so that we don't overload any providers. Even the dry-run involves up to 10 requests per client which can be very significant when the entire release population updates.
NextDNS is one of the providers that Mozilla selected for inclusion as a default HTTPS over DNS providers in the Firefox web browser.
This prefs-off a feature that seems to be effectively DDoS'ing NextDNS, one of our DNS over HTTPs providers. This patch is blocking the rollout of Fx77.
DNS over HTTPS is a new security and privacy feature that is being rolled out in Firefox, and also available in other browsers. Most browser makers, e.g. Google, plan to introduce support for DNS over HTTPS this year. Microsoft has integrated the feature in the company's Windows 10 operating system as well recently.
Mozilla stopped the rollout of Firefox 77.0 Stable because of the bug. The organization created a patch and plans to release it on June 3, 2020 to the Firefox Stable population.
