I have reloaded my pin tabs several times. They just disappear at restart. Any help would be appreciated.

Chosen solution

In case you are using "Clear history when Firefox closes":

  • do not clear Browsing History

Note that clearing "Site Preferences" clears all exceptions for cookies, images, pop-up windows, software installation, and passwords.


App (pinned) tabs and Tab Groups (Panorama) are stored as part of the session data in the sessionstore.js file in the Firefox profile folder.

If you use cleanup software like CCleaner then check the settings for the Firefox application.
