- Fix fingerprint-injection.patch: remove duplicate BrowsingContext line and fix hunk header
- Fix font-hijacker.patch: add space to blank line 125
- Fix no-search-engines.patch: add missing context for getProvider call in UrlbarProviderInterventions
- Disable webgl-spoofing-TEMP.patch to avoid conflicts
