Does the restore previous session call get destroyed too with the new forget button in firefox

Question

I have checked under startup to restore previous session ... Can it still if I use the new forget button since it states all tabs are closed ... so that would be last session to my thinking Rick Carter

Answer 1

I think there is a serious risk that your session history will be cleared, too. However, I haven't tested it yet. If you want to preserve a copy of your session history files while you experiment, you can back them up as follows:
Open your current Firefox settings (AKA Firefox profile) folder using either
* "3-bar" menu button > "?" button > Troubleshooting Information
* (menu bar) Help > Troubleshooting Information
* type or paste about:support in the address bar and press Enter
In the first table on the page, click the "Show Folder" button. This should launch a list of your settings files.
Look for a folder named '''sessionstore-backups''' and copy it in its entirely to a safe location such as your Documents folder.
You also should find a file named sessionstore.js which contains your current session windows and tabs. You could back that one up, too, but the recovery.js file in the sessionstore-backups folder should be identical or virtually identical (it may lag a little, but should be updated to be the same fairly quickly).
