I cannot restore previous session and tabs

Hi there,

It sounds like there may be a read/write issue with your Firefox profile, causing Firefox not to save settings. One thing you might want to try is Firefox Reset: https://support.mozilla.org/en-US/kb/reset-firefox-easily-fix-most-problems. While it's perhaps solving more problems than needed in this case, it tends to be a quick way of getting back on track for weird issues like this.

Thanks!

If you do not keep changes after a restart or otherwise have problems with preferences, see:

• http://kb.mozillazine.org/Preferences_not_saved

In case you are using "Clear history when Firefox closes":

• do not clear the Browsing History

• Tools > Options > Privacy > Firefox will: "Use custom settings for history": [X] "Clear history when Firefox closes" > Settings
• https://support.mozilla.org/kb/remove-recent-browsing-search-and-download-history

You can check for problems with the sessionstore.js and sessionstore.bak files in the Firefox profile folder that store session data.

• Help > Troubleshooting Information > Profile Directory: Show Folder (Linux: Open Directory; Mac: Show in Finder)
• http://kb.mozillazine.org/Profile_folder_-_Firefox
• http://kb.mozillazine.org/Multiple_profile_files_created

Deleting sessionstore.js will cause App Tabs and Tab Groups and open and closed (undo) tabs to get lost and you will have to recreate them (make a note or bookmark them if possible).

Thank you. Although following your advice did not solve the problem, when I opened Firefox an hour ago the problem seemed to have resolved sua sponte -- by itself! I have no idea why but hope it lasts.

Thanks again.
