Yes, this is intended. We disabled about:config and about:addons for beta and release builds.

I rely on making modifications to change custom pixel scaling when using Firefox Beta to use it as an "always in desktop mode" version of the app.

I know this veers off-topic but how can I do this in the future?
Is it only Nightly that has access to this now, or can you enable it again after enabling developer mode somehow?

Looks like it is still accessible but from this URL instead:

chrome://geckoview/content/config.xhtml

I can work with this!
