tabs and tab groups are lost

Closing Firefox and restarting it, invariably all my tab groups seem to have lost their tabs. Reopening hibernated groups or closed groups (using tab group manager add-on) will not help.

This did not happen on my previous install but since having upgraded to Kubuntu 14.04 and Firefox 29 (to be precise Firefox for Canonical 1.0) I keep losing my tabs and tab groups.

Do not know what mistake I am making.

Chosen solution

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

  • do not clear the Browsing History

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


You can check for problems with the sessionstore.js and sessionstore.bak files in the Firefox profile folder that store session data.

Rename (or delete) the sessionstore.js file and possible sessionstore-##.js 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 and you will have to recreate them (make a note or bookmark them if possible).
