Many thanks cor-el, I tried and still am greeted with the welcome page. I clicked "reset to defaults" and selected "show my home page" and even the "use a bookmark" but all to no avail. I am still shown the "Welcome to Firefox" page whenever I start up.

Did you try to delete the file prefs.js in the Firefox Profile Folder ?

I deleted the prefs file and all seems to be working OK now, many thanks for your help cor-el as I now start up with a blank page again.

You're welcome

I have this problem and tried this solution but it didn't work.

Did you check the Home page setting and if that is OK deleted the file prefs.js in the Firefox Profile Folder ?

I have rechecked my homepage and done everything above except I do not have a file called prefs.js. I have a file called prefs and another prefs.js.lpbak

Windows is probably hiding the .js file extension, so you only see a file prefs. You can check the Properties via the right-click context menu to see the file type.
