 Whenever you login into the SoGO webmail, the browser my ask you if you want to **Add "your.site" as an application for mailto links?**; this is because the SoGO Javascript executes a **window.navigator.registerProtocolHandler()** call. If you are annoyed by this request you can disable it at least in Firefox by visiting the **about:config** URL and changing **network.protocol-handler.external.mailto** to **false**.
+===== Session timeout =====
+After upgrading SoGO from **5.0.1** to **5.8.0** (e.g. by upgrading from **Debian 11 Bullseye** to **Debian 12 Bookworm**) the webmail session exipres in a few minutes, despite user activity. This is a known bug cause by a datbase table being not be properly updated.
+To fix the problem you can drop the faulty table from the SQL prompt and restart the SoGO service; the table will be re-created with the corrected structure:
+<code sql>
+DROP TABLE sogo_sessions_folder;
+</code>
+<code>
+systemctl restart sogo.service
+</code>
+This hack will upgrade the field **c_value** from **character varying(255)** to **character varying(4096)** (using the PostgreSQL backend).
