What happens if you use the first option ?

I remember reading about a change with browser settings and a user notification but was not aware it is in Firefox 18, I will check

P.S it will be a change this week when Firefox 19 is released
Bug 718088 - offer to re-set keyword.URL if it has a non-default value

i do not see that as a change in Firefox 18.

Try using this add-on (I think it installs an then goes away)

• https://addons.mozilla.org/en-US/firefox/addon/searchreset/
• and see this article What to do when searches take you to the wrong search website

when I choose option 1, nothing happens Also, the message does not indicate a firefox or mozilla message.

Hello alkazmir, see Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems

thank you

• What does the message come from ?
  • does it show in any of the Windows logs ?

• Is it possibly from security software you already have installed ?

Have you tried reading that articles in this thread linked from the blue text ?
