- - - - - 9357ba91 by Pier Angelo Vendrame at 2023-02-08T12:20:18+01:00 Bug 9173: Change the default Firefox profile directory to be relative.

This commit makes Firefox look for the default profile directory in a directory relative to the binary path. The directory can be specified through the --with-relative-data-dir. This is relative to the same directory as the firefox main binary for Linux and Windows.

On macOS, we remove Contents/MacOS from it. Or, in other words, the directory is relative to the application bundle.

This behavior can be overriden at runtime, by placing a file called system-install adjacent to the firefox main binary (also on macOS).
