Remove the SSB feature Firefox For bugs in Firefox Desktop, the Mozilla Foundation's web browser. For Firefox user interface issues in menus, bookmarks, location bar, and preferences. Many Firefox bugs will either be filed here or in the Core product. Bugs for developer tools (F12) should be filed in the DevTools product. (more info) User Story 3 months ago The SSB feature has only ever been available through a hidden pref and has multiple known bugs. Additionally user research found little to no perceived user benefit to the feature and so there is no intent to continue development on it at this time. As the feature is costing us time in terms of bug triage and keeping it around is sending the wrong signal that this is a supported feature we are going to remove the feature from Firefox.
