Firefox will not start on homepage. Always starts on last tab(s) open.

This problem has persisted since version 16. Settings in options are correct. I have tried changing different options and my settings file does save the new settings. I run a current version of Norton 360 and have used a separate malware detector Microsoft Safety Scanner. No malware. Troubleshooting information shows the correct setting for browser.startup.homepage. I'm lost, please help, thank you.

Try opening the user.js file. For me, it only had one line, which was user_pref("browser.sessionstore.resume_session_once", true);. Once I deleted the file, everything went back to normal. Hope this helps!

Make sure that Firefox closes properly and that there isn't a hanging Firefox or plugin-container process left in the task manager.

Use "Firefox/File > Exit" (Mac: "Firefox > Quit"; Linux: "File > Quit") to close Firefox if you are currently doing that by clicking the close X on the title bar.

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

Delete the sessionstore.js file and possible sessionstore-##.js files with a number and sessionstore.bak in the Firefox Profile Folder.

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

Tried all of the above. No problems with Firefox closing properly. I checked both methods of exiting and then checked taskbar. Both methods worked equally as well. I deleted sesionstore.js & .bak. Firefox opened to my homepage correctly but upon closing (both methods) when reopened, opened to last opened tab again.

Thank you, found that line at the end of the file, it was actually repeated 4 times. Deleted all 4 lines and saved the rest of the file. Working fine now. Thank you for your help ThePlatypus.
