My PC crashed and firefox was not able to restore my tabs. I've been keeping tabs for almost a year and all my sessions have always restored gracefully. I've seen the responses in MozillaZine and all of them don't seem to work anymore on the newer FF versions. sessionstore.bak and sessionstore.js in my FF 25.0 contains blank spaces when opened in notepad or null characters in other advanced editors such as notepad++ renaming sessionstore.bak to .js and deleting the other sessionstore files simply don't work. I'm begging for help please!!! :( losing my tabs is a pet peeve... highly irritating

The sessionstore.js file is a text file and if there are null bytes or other non-ASCII characters then it is likely that the file is corrupted.
If you have an older version of the file then you can try to use that.


You can try to restore a previous version of the file.
