Some tabs come up empty when starting Firefox and an error msg displayed "Unresponsive script chrome://browser/content/tabbrowser.xml:6366"
I confess I have two Firefox windows with hundreds of tabs in each. The error msg has stalled one of the windows this morning. The only way to work with that window was to click on the option 'Continue Script', after which I discovered about half of the tabs in that window were blanks. The option to Restore the Previous Session was greyed out (Firefox thinks it has restored it successfully?). I tried to refresh Firefox in safe mode, but no improvement: same error msg, same empty tabs. Also tried to copy a recovery.bak file from my Profiles/..../sessionstore-backups in place of sessionstore.js file in Old Firefox Data, hoping to regain the empty tabs, but alas. Is there any help? Can I regain those empty tabs somehow? Please let me know...

The oldest recovery.bak file in the oldest of my profiles (stored in Old Firefox Data) has blanks for some of the tabs in Window 1. Here is an excerpt:
{"entries":[{"url":"about:blank","charset":"","ID":4050297205,"docshellID":0,"docIdentifier":969,"persist":true}],"lastAccessed":1481519139253,"hidden":false,"attributes":{},"userContextId":0,"index":1,"image":null},{"entries":[{"url":"about:blank","charset":"","ID":4050297228,"docshellID":0,"docIdentifier":970,"persist":true}],"lastAccessed":1481514455914,"hidden":false,"attributes":{},"userContextId":0,"index":1,"userTypedValue":"","userTypedClear":0,"image":""},
and it continues to the end of Window 1. I went through all of my sessionstore-backups and couldn't find any in which these tabs had meaningful https. Is there any place where I could recover thosee addresses?
When all sessionstore files are corrupted and only have about:blank URLs then your only option would be to check the browsing history.
You can check in Windows Explorer if there is a previous version of the sessionstore.js file available.
- Right-click: Properties -> Previous Versions

Unfortunately, it seems I had to have my Explorer specifically configured to save previous versions of files, which I hadn't, and now I don't have an option to view/retrieve Previous Versions, Previous Versions is not an option in my Properties menu..... (( Any other ideas? (there had been a couple hundred URLs that have gone missing....)
You found the sessionstore-backups folder in the Old Firefox Data folder? Are any of other files (e.g., previous.js, or various upgrade files) close enough in time to be worth exploring? I assume you didn't accumulate all of those tabs in just the past few days...
If you do not have the Previous Versions tab, try this program to search for specific files within restore points (not as frequent as if you had configured backups, but possibly one is recent): http://nicbedford.co.uk/software/systemrestoreexplorer/
