Solve Locate Link Browser Pop-Up

If you found a pop-up box with words like “LOCATE LINK BROWSER” when you click on a link in an email, you are probably using Firefox as your default browser and you have probably just had an update to Firefox. When the update is installed, it changes registry setting which you will need to manually change per the following. After making the following changes, you will no longer get the Locate Link Browser message until the next time that Firefox is updated. Then, you will have to repeat the following Registry Edit.

1. Go to Start then Run then type regedit and click OK.Use the directory tree hierarchy to navigate to HKEY_CLASSES_ROOT\HTTP\shell\open\ddeexec”.
2. Delete the “ddeexec” registry key in it’s entirety
3. Repeat for “HKEY_CLASSES_ROOT\HTTPS\shell\open\ddeexec”.
4. Repeat for “HKEY_CLASSES_ROOT\Firefox\URL\shell\open\ddeexec”.
5. Repeat for “HKEY_CLASSES_ROOT\FirefoxHTML\shell\open\ddeexec”.
