lose tabs on closing

mpmassoff

The tabs/sites are no longer saved when closing the browser. The 'help' section on this issue is terrible. This is a MAJOR defect with version 4.0 (along with some others which I hope will be smoothed out with the next update). If this feature is not restored, how do I re-load the prior version? Is this even possible. This is horrible and I have had to resort to using explorer the last few days! Please rectify this immediately!

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

Make sure that you do not use Delete browsing, search and download history on Firefox to clear the "Browsing History"

yeah, I originally followed the instructions to make sure the file extensions were written correctly and tried to put them in correctly. Next suggestion? This is an automatic feature that should not have been disabled upon updating the software, especially when users became accustomed to it.
