Version 5.71
Released Jul 18, 2026 - 491.86 KBWorks with firefox 109.0 and later, android 120.0 and laterClicking the extension icon in the Firefox toolbar now opens the PGP Suite interface in a new tab instead of a popup. This provides a larger, more comfortable working area without the size constraints of a browser popup.
Thesidebar_actionmanifest entry has been removed. Previously, clicking the toolbar icon would open both a new tab and the sidebar simultaneously. The sidebar toggle button has been removed to avoid this conflict. The extension now opens exclusively in a new tab when the toolbar icon is clicked.Source code released under GNU General Public License v3.0 only
Version 5.70
Released Jul 16, 2026 - 491.85 KBWorks with firefox 109.0 and later, android 120.0 and laterA new Persistent Vault tab has been added, allowing you to securely store sensitive notes and credentials encrypted with your own PGP key directly in the browser.
- Create entries by selecting one of your own private keys, writing your sensitive content (passwords, usernames, notes, etc.), and clicking Encrypt & Save. The content is encrypted with your key's public key and stored persistently in
browser.storage.local— surviving browser restarts. - View and edit entries by entering your key's passphrase and clicking Unlock & Edit. Once decrypted, the content becomes editable in-place.
- Save changes by clicking Re-encrypt & Save, which re-encrypts the updated content and overwrites the stored entry.
- Lock an entry at any time to clear it from session memory and return it to its encrypted state.
- Delete an entry — only available after successfully decrypting it, proving ownership.
- Only your own private keys (keys for which you hold the private key) are available in the key selection dropdown. Imported-only public keys are excluded.
- Decrypted content is held in session memory only and is never written to disk in plaintext.
- An entry cannot be edited or deleted without first successfully decrypting it with the correct passphrase.
- Added Persistent Vault tab to the main navigation.
- Added
VaultControllerclass inui.jshandling all vault UI logic (create, decrypt, edit, re-encrypt, lock, delete). - Vault entries are stored under the
MiniPGP_vaultkey inbrowser.storage.local. - Tab switching to the Vault tab automatically refreshes the key dropdown and entry list.
