Every time I start my computer & open Firefox, instead of pulling up my home page, it acts as if it just crashed and brings up the page that shows it crashed/is trying to re-open my previously opened tabs. (Page displays: "Well, this is embarrassing. Firefox is having trouble recovering your windows and tabs. This is usually caused by a recently opened web page." Then it lists all the tabs I had opened the last time I had my computer on). I have deleted Firefox & downloaded a previous version, and that corrected the problem for a few days. Now the same problem is back. How do I fix this?

A possible cause is that you are first closing all Firefox windows and then close the Firefox application.

Some have reported that closing Firefox (Firefox > Quit) while the browser window is still open works for them.

If this still doesn't work properly then you can consider to disable crash recovery, but note that you will lose open tabs in case a real crash occurs.
