------------------------------------------------------------------------------------------------------------------------------------------- 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. ---------------------------------------------------------------------------------------------------------
