I'd like the MRU Tab history to be preserved across sessions.

Most Recently Used (MRU) tab history used to be preserved across sessions, if my memory serves, so reopening a session was almost like you hadn't left it. Now with hundreds of tabs its hard to pick back up and proceed as if uninterrupted. The loss of MRU tab history is a tremendous reduction in usefulness.

Is there any hope this will be restored?

Is there anything to do to increase the chances of it being restored?

Are there any extensions that will restore the MRU tab history form the pression session when a session is reopened?

Not that I know of, but I can think of an add on that has similar functionality:

This option is available for the current session. Restoring this list is available in all of your history if it is preserved as well.

It is possible to leave feedback for the developers about this feature at input.mozilla.org.

Current Firefox versions only store a maximum of 10 entries of tab back history as part of stored session data in the sessionstore.js file. So you lose tab back history beyond those ten entries when you use "Show my windows and tabs from last time" to restore open tabs on the next start. The default is 10 and a value of -1 will disable this maximum and allows to keep all back history entries.

You can open the about:config page via the location/address bar. You can accept the warning and click "I'll be careful" to continue.

See the description of pref(s) in this file (open via the location bar):

  • resource:///defaults/pref/firefox.js
// number of back button session history entries to restore (-1 = all of them)
pref("browser.sessionstore.max_serialize_back", 10);
// number of forward button session history entries to restore (-1 = all of them)
pref("browser.sessionstore.max_serialize_forward", -1);
