Why when I reopen Firefox, some of my anchored tabs are duplicated and some disappear?

I have anchred the websites I mostly use (gmail, facebook, google+, etc.) so when I open the browser I have all I need ready. The problem is that when I open the browser, I always have some tabs two times and other disappeared. ie. Today I opened and I found: gmail, facebook, twitter (where yesterday was google+), twitter again, a web for bills payments, that web again (where yesterday was the page of bank "A"), the page of bank "B". But every day I fix the tabs and the next day I have a different configuration of fixed tabs.

It is possible that there is a problem with the files sessionstore.js and sessionstore.bak in the Firefox Profile Folder.

Delete the files sessionstore.js and sessionstore.bak in the Firefox Profile Folder.

If you see files sessionstore-##.js with a number in the left part of the name like sessionstore-1.js then delete those as well.
Deleting sessionstore.js will cause App Tabs and Tab Groups and all open tabs to get lost, so you will have to create them again (make a note or bookmark them).
