All my automatic Bookmark Backups have no data in them and the word undefined at the end
All my automatic bookmark backups are listed with 0 bytes, contain no data and have the work "undefined" at the end. How do I ensure that my backups go back to saving as normal?

I have not looked at the inner workings as thoroughly as Marco. However, the last time I was able to backup w/o experiencing 0 json was 12/28/13. i think there is a corruption issue in the bookmarks file that occurred around that date.
Is there a program to scan the bookmarks file for corruption markers and make corrections ?
Hi Steve, I think the problem at this point is understanding why Firefox 23 could work with these same files but Firefox 24+ or 25+ chokes on them. Until we know what characters or missing fields or other issue is causing the problem, we wouldn't know what to scan for.
Got it, thanks. I still save my sessions and back up my places.sqlite periodically.
In my case there is also the lack of parity between automated bookmark backups saving with no data and the "undefined" file ID, but exporting html and json backups of bookmarks works just fine.
I tried Safe Mode with add-ons disabled and every time I did this it saved an automatic backup with a numeric, not dated, ending (eg "bookmarks-2014-01-12_361") but with data in it as usual instead of it being an empty file. When switched back with Addons enabled it continues to save empty files with "undefined" at the end.
This still doesn't seem to present full functionality as it should obviously be dated at the end and not just a 3 figure number, also I can't see how an Add-On could suddenly cause such significant issues with a core backup process as I don't have anything other than a few security Add-Ons and some for aesthetic adjustments to the interface?
These might be worth toggling if you keep the compilers enabled:
Thanks for those suggestions jscher2000, I gave it a try but I'm afraid that it did not affect the bookmark backups.
A possible cause can be that Firefox isn't closing properly for some reason and isn't able to write a correct sessionstore.js file.
Did you try a new profile?
See "Creating a profile":
If the new profile works then you can transfer some files from an existing profile to the new profile, but be cautious not to copy corrupted files to avoid carrying over the problem.
In Firefox Safe mode these changes are effective:
- all extensions are disabled (about:addons)
- default theme is used (no persona)
- userChrome.css and userContent.css are ignored (chrome folder)
- default toolbar layout is used (file: localstore-safe.rdf)
- hardware acceleration is disabled (Options > Advanced > General)
- plugins are not affected
- preferences are not affected
