Manufacturer: LibreWolf Community

The bottom line

When Firefox patches a critical zero-day, LibreWolf users have to wait 1-2 days for the community to rebuild and release it. During that window, you're running a browser with a known exploitable vulnerability. No paid team, no guaranteed timeline. LibreWolf disables Google's phishing protection by default. Nobody is watching your URLs — which means nobody warns you about fake bank sites either. Netflix won't work out of the box. Maximum privacy, minimum convenience.

Findings by concern
Data Sharing 1/4 LOW 1 finding
✔️ lowfirmware analysis vs regulatory findings
No company behind LibreWolf means no one can be forced to hand over your data. It also means no guaranteed security team if something goes wrong. They moved to Codeberg because even GitHub (Microsoft) was too much corporate control.

What they claim: LibreWolf is a community project with no corporate entity

What we found: No company means no one to subpoena, no shareholders pushing monetisation, no business model conflicting with privacy. But it also means no formal incident response team, no SOC 2 certification, no guarantee of continued maintenance. The project moved from GitHub to Codeberg in October 2025 for sovereignty reasons.

⚫ mediumfirmware analysis vs app permissions
When Firefox patches a critical zero-day, LibreWolf users have to wait 1-2 days for the community to rebuild and release it. During that window, you're running a browser with a known exploitable vulnerability. No paid team, no guaranteed timeline.

What they claim: LibreWolf strips all telemetry from Firefox — zero phone-home on launch

What we found: LibreWolf's security updates lag behind Firefox by 1-2 days. When a critical Firefox zero-day is disclosed (like CVE-2024-9680, CVSS 9.8, actively exploited), LibreWolf users are exposed until the community builds and pushes the update. There is no paid security team and no SLA for patch turnaround.

⚫ mediumpolicy claims vs firmware analysis
LibreWolf disables Google's phishing protection by default. Nobody is watching your URLs — which means nobody warns you about fake bank sites either. Netflix won't work out of the box. Maximum privacy, minimum convenience.

What they claim: LibreWolf is fully open source with zero telemetry and zero tracking

What we found: Safe Browsing (Google's phishing protection) is disabled by default. This means LibreWolf won't warn you about known phishing sites or malware downloads. Maximum privacy comes at the cost of a safety net that protects most users from the most common threats. DRM is also disabled — Netflix and Spotify won't work without manual configuration.
