Tab history dropdown list too short after session restore?

Posted

After restoring a previous session, and holding down the back button to show the tab history dropdown list, it only shows the last 10 pages visited. What setting, in about:config, allows me to increase this number?

Found it. It's "browser.sessionstore.max_serialize_back" . The default value is 10. In order to make it so that there is no limit to the number of pages you can go back, set this value to -1.

Note that "browser.sessionstore.max_serialize_forward" is set to -1 by default; so there is already no limit to the number of pages you can go forward, oddly enough.
