I use Session Manger and love this add on. Now for some reason I must start Firefox in Safe Mode and then close it and then reopen normally and it appears that session manger is causing this problem. How do I fix this??

I suddenly need to start Firefox in Safe Mode or it will not open. The problem after deleting extensions and adding profiles appears to be Session Manager which I have been using successfully for along time and really enjoy its usefulness. is there a fix to this problem?? Thank you.

I'm not using that extension, so I do not know which files are used in addition to sessionstore.js and you need to check the profile folder yourself for suspect files.

This can be a problem with the file sessionstore.js in the Profile Folder
Delete the files sessionstore.js and sessionstore.bak and any existing files sessionstore-##.js with a number in the left part of the name like sessionstore-1.js .
