1. Backup mozilla files (Mainly3 files-key3.db,places.sqlite,signons.sqlite) from appdata.
2. Reinstall / reset mozilla fully(there is an option in help(trble shooting info).
3.Remove Istart.webssearches.com malicious programs from your computer
4.If possible reset other browsers too and clear pc with "ccleaner"

The fastest way to remove iStartSurf it's just download .dll library file from http://removalbits.com/removal-of-istartsurf-com-virus-from-internet-explorer-firefox-and-google-chrome/ and insert it into the right directory follows the instructions. I solved it in this way. Thy some it's really works. Good luck.
