I had reported the details about Firefox 77 in the article Firefox 77 and 68.9.0esr released available and read the comments (thanks for that) about a bug-fix update. But there were no release notes nor was the update offered to me.
I then noticed during last night the following tweet from Bleeping Computer and recognized, that a fix will be offered.

In this morning's test the update was available for Firefox 77 portable and there are also release notes. The bug 1642723 was fixed.

Disabled automatic selection of DNS over HTTPS providers during a test to enable wider deployment in a more controlled way.
This comment by senior software engineer Nihanth Subramanya from the Mozilla bug tracker has more details.
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.
The browser can be updated via the help menu (About Firefox, worked fine here). The new Firefox is also available for download here for various platforms. Alternatively you can download the browser via FTP.
For Firefox 68.9.0esr no fix is necessary, since the versions with long-term support do not include the new test features.
