I recently updated to Firefox 8. I used the tutorial to set pin apps. I have not selected the option to clear all history when firefox closed, but pin apps disappear anyway and are not there when firefox is reopened.

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

Using the "Show my windows and tabs from last time" setting is a more reliable way to restore session data.


It is possible that there is a problem with the files sessionstore.js and sessionstore.bak in the Firefox Profile Folder.

Delete the sessionstore.js [2] file and possible sessionstore-##.js [3] files with a number and sessionstore.bak in the Firefox Profile Folder.

Deleting sessionstore.js will cause App Tabs and Tab Groups and open and closed (undo) tabs to get lost, so you will have to create them again (make a note or bookmark them).

I had to set Firefox as my homepage. That seemed to work. Thank you all for your suggestions!
