It's a long story, but to put it simply - I can't recover my sessions. Each time I do it a have an error - with each session, either backuped or saved.

I know it's not totally your profile, but if you can help me with this one - please do. I had encountered those earlier, but each time i had older backups that worked. Now I don't - and I have no other means to save my data. Please help me.

Each time I get this error log: (first line is translated from russian, but I guess it is pretty clear)

-Data on the session / window damaged:
JSON.parse: expected ',' or '}' after property value in object at line 1 column 11923 of the JSON data(SyntaxError)

It sounds like your files may have been corrupted. Do you have any old backups? I've called the big guys to help you. Good luck.


Start Firefox in Safe Mode {web Link} by holding down the <Shift>
(Mac Options)
key, and then starting Firefox. Is the problem still there?

That still Doesn't help me, and I don't have any backup, so if I can't use this files, it means i lost my whole data.

These are errors usually show up in an error log. The error will have the file path and the line of code that there is an error in.

It might be wise to also rope in the Session Manager developer into this one. It sounds like it is corrupt and cannot be fixed.

Do the old files work in a new install of Session Manager?

The grueling path for manually fixing files that have become corrupt or just not working might be to create a new profile in Firefox, install the same add on then save a session that works. Open the working file in a text editor and the non working one and see if there is anything missing.
