Research direction

Start by tracing how the launcher handles the Firefox startup URL and the url configuration, then reproduce the behavior with browser.startup.page set to 3. Done means launching Firefox without adding an unwanted about:blank tab while preserving the requested session-restore behavior.

Written by the indexing model from the issue text.

Description

By default, firefox opens new tab with about:blank, If user.js set to user_pref("browser.startup.page", 3); (restore previous session), it will open additional new tab each time firefox has started.
Attempting set "url": "" in launcher is ignored. So far, I'm unable find a way launch firefox without opening any new tabs.
