I can't remove the fake "your computer is locked up" message, despite following advice on your and other sites. I even trashed Firefox, downloaded a new one, but on opening it, scam message reappears. I haven't found any solutions in the on-line forums I looked at.

You can do a malware scan, just to be sure.
You can check that those pages aren't set as multiple homepages.
You can check the homepage setting in "Settings -> Home".
Firefox supports multiple homepages separated by '|' (pipe) symbols.
Try to start Firefox in Troubleshoot Mode to see if that works.
- Mac: hold down the Options key while starting Firefox
- Windows: hold down the Shift key while starting Firefox
