Firefox writes contents of Session Restore to sessionstore-backups/recovery.js whenever it is required.They too can be used to replace the main sessionstore.js file should it be corrupt. These files contain session information from the last shutdown or upgrade. You can still use these files and replace the sessionstore.js file in the main directory.Īdditionally, you find previous.js and upgrade.js there as well.

You can use the other session backups listed there as well to restore sessions.

The primary backup file is recovery.js now, the secondary backup file recovery.bak. Note that sessionstore.js is only shown when Firefox is not open. While sessionstore.js is still stored in the main Firefox profile folder, all other files are now stored in sessionstore-backups instead. Mozilla has improved the Session Restore feature in Firefox 33. May still be useful for old versions of Firefox, and Firefox-based browsers such as Pale Moon. If it does not, press the Alt-key on your keyboard and select History > Restore Previous Session.

Mozilla changed the format of session backup files and that means that the previous way of restoring sessions needed updating. Use these if previous.jsonlz4 fails to do the trick. upgrade.jsonlz4-"number" - previous session backups, usually created during upgrades of the browser.previous.jsonlz4 - the last session backup that Firefox created.This is the file that you want to try to restore first (unless it has a very low size).
