This bug is a dupe of so many of the same bugs it is getting crazy. It has happened for me ever since (maybe before). 

It is most definitely NOT fixed.... Stop closing the bugs as "verified fixed"

Every other dupe (this one included) of this bug suggests deleting the ddeexec keys from the registry entries below, but this is only a temporary fix. After your Firefox installation "auto upgrades" it breaks the registry keys again!

The problem is recreated when the upgrade adds the ddeexec keys with the (default) string value of "%1",,0,0,,,,

To fix (temporary, will break again on update or reinstall), remove the ddeexec entries from the following keys:


(May be more keys, but this is all I could find so far)

This is a verified issue with both Windows XP and Windows Vista (all versions)

I had the same problem and after reading trial solutions today, I went to explore in Vista Home Premium. Hit alt+T to bring up tools menu and go to search. Check "do not use index when searching" and the problem seems to be solved. Apparently, the index contains URLs from past windows searches, and this fix seems to eliminate that problem.
After closing out of everything, the same dialogs reappeared. I will have to try further remedies.
I just eliminated the ddeexec keys in the registry. The two eliminated were in HKCR/firefoxHTML/shell/open and HKCR/firefoxURL/shell/open. If the bug returns after an update, I will just delete those keys.
Bug 389502 is a tracking bug for issues related to this problem.
The "Windows cannot find 'http: " error message still pops up in the latest 
Mozilla Firefox 3 Beta 5 ( Build 2008032620 )
when you click on a short cut in Windows XP when Firefox is not running.
Component: Software Update → OS Integration
QA Contact: software.update → os.integration
Still does it in 3.6.3, Windows XP.
Version: unspecified → 3.6 Branch
check up ur internet port connection

I think this was fixed by the removal of DDE so resolving as wfm. If you are still experiencing this bug please comment in this bug or better yet please file a new bug. Thanks!
