Details

The preferences file reader in prefs.py currently reads from the user.js files, translates it into a python-like structure and then uses the python parser to read the values.

This causes workarounds like we're having to do in bug 1830265 for multiline preferences.

We should be using a JavaScript AST parser to avoid these types of workaround being necessary, and it would be more reliable overall that trying to translate into python.

Gijs also suggested using Firefox's Rust-based libpref parser directly, which may be possible using something like maturin
