Can't use session restore after Refreshing Firefox

After Firefox started running slowly, I took its advice and Refreshed it.

It lost my session restore data.

I've been able to find a recent backup (in a folder marked "Old Firefox Data") but not use it.

I've checked a variety of similar questions, looked at the ghacks article, tried closing Firefox and replacing sessionstore.js with a backup that I know is the right one, but I just keep getting my (useless) tabs from after the refresh.

Hi Sturrock, which file from your Old Firefox Data were you trying to restore?

I haven't used Refresh recently. Could you tell me which of these files you find in the sessionstore-backups folder in your old settings?

  • recovery.js: the windows and tabs in your live Firefox session from the time of the Refresh
  • recovery.bak: a backup copy of recovery.js
  • previous.js: the windows and tabs in the previous Firefox session
  • upgrade.js-build_id: the windows and tabs in the Firefox session that was live at the time of your last update

Note: By default, Windows hides the .js extension. To ensure that you are looking at the files I mentioned, you may want to turn off that feature. This article has the steps: http://windows.microsoft.com/en-us/windows/show-hide-file-name-extensions

Aha! Just tried restoring from the most recent of the upgrade files, by renaming it and moving it, and that worked -- thank you!
