I get Subject Error page upon initial launch. I tried the going to about:config and confirming the browser.sessionstore.max_resumed_crashes was set to 1. I also made sure I Quit FF before shutdown. (No FF tasks in Task manager) Neither of these worked for me. Running the current version of Windows 10.

You can check if you have a user.js file in the Firefox profile folder that sets the browser.sessionstore.resume_session_once pref to true.

  • browser.sessionstore.resume_session_once

You can check for problems with the sessionstore.jsonlz4 file in the Firefox profile folder that stores session data.

  • delete sessionstore.jsonlz4 and sessionstore.js

When sessionstore.jsonlz4 is deleted you lose pinned-tabs and open tabs and you will have to recreate them, so if necessary make a note or bookmark them. sessionstore.jsonlz4 is only present in the Firefox profile folder when Firefox is closed.

You can use the button on the "Help -> Troubleshooting Information" (about:support) page to go to the current Firefox profile folder or use the about:profiles page.
