org.mozilla.reference.browser.debug:tab W/Web Content: [JavaScript Warning: "Navigation to toplevel data: URI not allowed (Blocked loading of: “data:text/html;base64,PCFkb2N0eXBlIGh0bWw+PCEtLSBU...”)" {file: "about:blank" line: 0}]

Hmm.. seems like something changed in GV js policies?

about:version triggers the app's request interceptor which then calls GeckoView#loadData.

The same is happening for about:privatebrowsing.

A fix for about pages landed yesterday (autoland).

@pocmo: Do you know if mozilla-mobile/focus-android#4299 has the same cause? I know that the development of Focus is on hold at the moment, but still an update was released via Google Play Store more than three weeks ago and it's a bit sad that nobody seems to care about new regressions on the release channel. Would be interesting to know at least if it's the same issue.

@cadeyrn Yes, this looks like it's the same thing.

This is fixed. Closing!
