Prevent Firefox from reloading pinned tabs at startup

Posted on Wed 08 July 2015 in tech

Firefox has a setting "Don't load tabs until selected". But enabling this will not prevent Firefox from reloading every pinned tab at startup. Fortunately there seems to be a specific preference for this one too:

  • open about:config
  • set browser.sessionstore.restore_pinned_tabs_on_demand to true
