How to enable automatic session restore after a crash

Posted

I am trying to enable automatic session restore after a crash. I set browser.sessionstore.resume_from_crash to true, but it reverts back to false. Is there is a dependency on another setting that is causing it to revert? Or some other means of enabling automatic crash recovery?

The 'When Firefox starts' option is set to 'Show my windows and tabs from last time'. I am not running any session management extensions.

All browser.sessionstore settings have default values except these: browser.sessionstore.max_tabs_undo: 500 browser.sessionstore.max_windows_undo: 100 browser.sessionstore.restore_hidden_tabs: true browser.sessionstore.resume_from_crash: false

Thanks!

Chosen solution

Start Firefox in Safe Mode to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance).

  • Do NOT click the Reset button on the Safe Mode start window or otherwise make changes.

If you do not keep changes after a restart then see:

cor-el, thanks very much! The problem was this line in in user.js: user_pref("browser.sessionstore.resume_from_crash", false);
