v2026.0630

Built on LibreWolf 152.0-1.

Fix: Installer now cleans up stale startup entries from previous or test installs, preventing multiple browser instances from launching on reboot.

Wisp 2026.0627

Built on LibreWolf 152.0-1.

Changes

• Preload 4 extensions (uBlock Origin, SponsorBlock, Bitwarden, Clear Cache) and allow in private browsing
• Pin 4 extensions to toolbar
• Enforce First-Party Isolation
• Simplify README; add personal-use framing and list pre-installed extensions
• Remove internal build plan docs from repo

Known limits

• Installer is unsigned — SmartScreen will warn on first run. Click More info → Run anyway.
• Verify the download: Get-FileHash Wisp-Setup-2026.0627.exe -Algorithm SHA256 and compare against the .sha256 file.
• SHA-256: 2fd213d83346cbedab0cd2f604789f5d44a60bbad4fb8467343e213e554d4c68

Wisp v2026.0620

Wisp v2026.0620

Wisp's first release: a privacy-hardened config overlay on LibreWolf, packaged as a self-contained Windows installer.

What's in this build

• Built on LibreWolf 152.0-1
• Locked hardening: resistFingerprinting, HTTPS-only mode, strict content-blocking category, telemetry off, all extension/dictionary/theme installs blocked
• DNS-level ad/tracker/malware blocking via DoH, defaulting to Mullvad (Base) — user-changeable in Settings → Privacy & Security → DNS over HTTPS. Note: this means Mullvad sees your DNS queries by design; swap providers there if you'd rather use your own (e.g. a pi-hole or dns0).
• Always-on private browsing: no persistent history, cookies, or session restore across restarts
• Full Wisp rebrand (name, icon, About dialog) across all ~104 LibreWolf locales
• Installs per-user, no admin rights required

Known limits

• Unsigned build — Windows SmartScreen will warn on first run. Click "More info" → "Run anyway" to proceed. Verify the download against the checksum below instead. Code signing is being evaluated for a future release; no date is committed yet.
• No per-site exceptions UI, no custom settings page
• Some sites may break under the blanket extension-install block or strict tracking protection — please file an issue if you hit one
