LibrifyJS: change.org (experimental) oleh h3nn3s

GNU LibreJS blocks the non-libre JavaScript running on change.org which makes the site unusable. This extension replaces the blocked code with liberated JavaScript which makes the site functional again.

⚠️ This extension is currently experimental and unfinished.

# What Works

- Petition signing form (in some cases)

# What Doesn't Work

- Probably anything else
