well, firefox main window -> tools-> options ->general settings tab, see the homepage setting, you'd choose display "my homepage" then type in what url you want. then ok. then test firefox. if you choose display blank page, then type in whatever, it doesn't help.

Make sure that you do not use [[Clear Recent History]] to clear the "Browsing History" if Firefox is closed. ---- This can also be a problem with the files [http://kb.mozillazine.org/sessionstore.js sessionstore.js] and sessionstore.bak in the [http://kb.mozillazine.org/Profile_folder_-_Firefox Profile Folder] Delete [http://kb.mozillazine.org/sessionstore.js sessionstore.js] and sessionstore.bak in the [http://kb.mozillazine.org/Profile_folder_-_Firefox Profile Folder] * Help > Troubleshooting Information > Profile Directory: Open Containing Folder If you see files sessionstore-##.js with a number in the left part of the name like sessionstore-1.js then delete those as well.<br /> You will have to redo App Tabs and Tab Groups after deleting sessionstore.js.
