Suddenly Firefox starts with the last page viewed.

Firefox Tab basics

I'm running Firefox 24.0 on Windows 7. Suddenly when I start Firefox I wind up on the last page viewed, tabs and all. I went to Options, set it to blank. Went to about:config and made the change there. No luck.

I'm not certain, but I think this started with this week's Microsoft download.

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

You can use this button to go to the Firefox profile folder:

I renamed the user file to something Firefox wouldn't recognize. (xxxx) and the problem went away.

I hope this doesn't upset the sync process.

Thank you.
