1388471 - Add a configuration option for "this is a local development build"

Status: NEW

(Firefox Build System :: General, enhancement)

Description

[Brian Grinstead [:bgrins]]

Spinning this discussion out from https://bugzilla.mozilla.org/show_bug.cgi?id=1385452#c9.

There's a few places where we want to run code or change a preference only in a local development build. Right now we use !MOZILLA_OFFICIAL for that, but it's not obvious what it means when reading the code, and it's potentially not reliable.

There are a couple of usages of Services.appinfo.isOfficial that could potentially be switched to a new option as well

Rereading this after all these years... isn't this covered by DEVELOPER_OPTIONS?
