How can I access the savestore.js contents if the command about:sessionrestore shows a blank box even for already succesfully used backups?


Is there a recent known problem with the about:sessionrestore command or is there any other way understandable to Firefox 29.0.1 through which recover the information stored in the sessionstore.js files.


It seems the command about:sessionrestore is not capable anymore to read the contents of the sessionstore.js file present in the user profile folder.

The box where windows and tabs should be listed is empty.

I tried to paste a few old sessionstore.js files in the user directory while the firefox.exe process was not active, then opened Firefox again and tried to launch the about:sessionrestore command without any result.

I think the files are not corrupted because I used most of them in other occasions and I stored them in folders not connected to the common use of any process.

Also, I already successfully used the about:sessionrestore command in Firefox 29.0.1 in a few other occasions.

I did a "clean reinstall" of Firefox 29.0.1 and the box contained in the tab where about:sessionrestore is executed is still empty even if the files themselves contain such information as tabs location and html addresses.

After this I recovered the profile data I had stored in another folder and this is what you can see attached to this question.

If I select the "show my windows and tabs from last time" option in the startup settings the contents of any savestore.js file i paste in the user profile folder are opened without any problem.

still, the box in the tab loaded by the about:sessionrestore command is blank and empty, so it's not possible to "de-select" any window or tab. it's necessary to find an editor to modify session backup files which may contain "bad addresses".

does such an editor already exists?
