Key notes

Firefox is one of thestrongest browsers for all devices, with ease of use to boot. The restore previous session feature is one of its endearing features that aid productivity.

This feature allows users to regain access to their opened windows after closing the browser. With this comes a much welcome continuity and ease of access.

However, users are starting to complain that the restore previous session feature is not working on Firefox. Fortunately, it is not the most difficult issue to solve, as we will show in this article.

Quick Tip:

If you want to fix this issue fast, try using a different browser instead. For good performance and low error rates, we recommend Opera.

This browser is light and often updated, so you shouldn’t have the same problem with restoring previous sessions. It uses very few resources and includes an adblocker, a VPN, and more.

How do I turn on the previous restore session in Firefox?

Where are previous Firefox sessions stored?

Firefox stores the previous session files in the profile folder on your PC. To locate the files, just open File Explorer and follow the path:C:\Users/Username/AppData/Roaming/Mozilla/Firefox/Profiles/profile folder/sessionstore-backups

Note that the file tagged previous.jsonlz24 is the last saved session on Firefox. So, it is the file you might want to restore.

How do I restore a previous Firefox session when the feature is not working?

1. Quit Firefox with all windows open

The restore previous session only works on Firefox if the browser does not close properly. This might be due to a crash, update, or accidentally closing a window.

If you exit Firefox by clicking the close icon at the top right corner of every window, that will not qualify as an accidental closure. So, the previous restore session will not work for you.

But if you use the Exit option, it will close all windows at once, which allows you to use the feature the next time you open your browser.

2. Update Firefox

An outdated browser might be why the restore previous session feature is not working on Firefox. This might be due to a bug or other issues fixed in a newer version.

3. Restore session with history

Provided that you have enabled the restore previous session in your settings, this fix will help you get your previous windows back on Firefox.

4. Uninstall and reinstall Firefox

Sometimes, the reason the restore previous session is not working on Firefox might be due to a problem with the browser on your PC. The best thing to do is to remove Firefox and all its components and reinstall it.

When the restore previous session is not working on Firefox, you might have to start reloading all your windows manually from the browser history. This not only makes you miss out on some pages but also takes away an important ease of use feature of your browser.

But with the fixes in this guide, you should be able to solve the problem for good. Are you facing other issues likeFirefox not responding? Then, check our detailed article on the topic to fix it quickly.
