When Firefox is opened with a URL, the URL is a parameter in Firefox's command line and could present a potential privacy leak as it is not cleared by Clear Recent History.

In addition, right click on Firefox's launch icon, click "Properties", note the third line; the "COMMAND" entry which most likely reads "Firefox -u". The "-u" is what Anonymous is referring to as a parameter. It (-u) represents an instruction to Firefox to replace your destination URL with another destination that is not intended.

This may point to a virus in an applet, could be a porn site, whatever.


If a pop-up box asks for permission to download a file, DO NOT CLICK OK.


Click "Cancel".


I did a cold boot out of instinct next, then get rid of that "-u". I cannot speak for the clear history but it sounds like a good idea, also. I made sure I had a BACKUP of my bookmarks as a precaution, then did what Anonymous suggested.

Another thought I only have one icon, so cannot vouch for it but you may need to remove the "-u" on each launch Firefox you have.

Also, do not be as blasé as I was, if the URL looks wrong, it probably is wrong. Go browse somewhere else.
