firefox: 'this.getEditor() is null' if doc._id is 'settings'

[kinesias]

This seems to be a Firefox > 65 issue.
I have a document with the _id 'settings'. If I open the doc in Firefox via Fauxton, the entire page becomes blank and I get the following stacktrace in the console:

TypeError: "this.getEditor(...) is null"

This error only happens if the doc._id is 'settings'.
It does however work perfectly in Safari and Chrome.

Environment:
Fauxton on Apache CouchDB v.2.3.1
MacOS 10.13.6

@kinesias What was the database name? Are you still able to reproduce the error?

[kinesias]

Now, I know why this is happening: it occurs when a document has CONFLICTs: if a document is in conflict mode, I get a white screen of death -- but only in Firefox.

[Darren Cook]

I just hit this (Firefox 69), and yes it turned out to be a conflict.
Is there a workaround? (Other than having to open fauxton in chrome and tell it to resolve all conflicts.)

[Angelo Teixeira]

I think this error still persists, is there any update?

[Diana Barsan]

This is happening in Chrome 91.0.4472.114.
