Are all the tabs open when my laptop is powered up the next day and my previous session is restored?

I have Firefox set to restore all my tabs that were showing on my previous session. My question is are those tabs actually "open" and adding to the workload of the laptop every day when I power up again? When I do click on one it takes a while to actually open, but during that session if I go back to that tab it instantly is open. I have several hundred tabs saved this way at any time, but am assuming they are not open until the 1st time I open one each session. Thanks!

There are two 'on_demand' prefs (browser.sessionstore.restore*on_demand) that control whether tabs are restored when you restore a session. You can set both prefs to true on the about:config page to always open the tabs on demand (i.e. you need to focus a tab to load it).

  • browser.sessionstore.restore_on_demand = true
  • browser.sessionstore.restore_pinned_tabs_on_demand = true

You can open the about:config page via the location/address bar. You can click the button to "Accept the Risk and Continue".
