In Vista with the latest Firefox update, You might have noticed a problem when opening URLs in applications like Outlook or even the Windows Sidebar. you will get a popup like this below


If you want to fix this error follow this procedure

Go to start>run type regedit click ok

Now you need to navigate the following key from left pane

HKEY_CLASSES_ROOT\FirefoxURL\shell\open\ddeexec

Now you need to Double click on the Default REG_SZ registry value from right hand side, which should have a value of “”%1″,,0,0,,,,”. Delete that value and leave it blank.

Close and exit registry editor

Now you should be able to open links from outlook in firefox without any problem.

For Windows XP and Windows 2000 User

Open Windows Explorer (or My Computer).

Go to Tools -> Folder Options -> File Types

Select Extension: “(NONE)” File Type: “URL:HyperText Transfer Protocol”

Click “Advanced”. In the “Edit File Type” window, select “open” and click “Edit”

Uncheck “Use DDE” (the dialog should then hide the lower part).

Click OK for that dialog and the next one (afterwards, the “Use DDE” box is still checked but the “DDE Message” box will be cleared)

Repeat for Extension: “(NONE)” File Type: “URL:HyperText Transfer Protocol with Privacy” (and any other protocols you want to fix)

Repeat for Extension: “(NONE)” File Type: “Firefox URL”

Repeat for Extension: “HTM” (or “HTML”) File Type: “Firefox Document”

  3. Can anyone help.When opening an email if I click on the web address of a company etc, outlook wont go there unless I have Internet explorer already open, its giving my the irrates. Hope someone can help

  4. @sue
    You need to make sure if you are using IE as your default web browser.Which OS you are using XP or vista

    or try this

    Open Windows Explorer> Tools> Folder Options> File Types tab. Highlight URL:HyperText Transfer Protocol click Advanced button then Edit button. Under Application used to perform action it should read:
    “C:\Program Files\Internet Explorer\iexplore.exe” -nohome

    Hope this helps

  10. I recently installed Windows 7 and was having the described problem of not being able to open links in firefox from outlook. I followed the directions above…

    Go to start>run type regedit click ok

    Now you need to navigate the following key from left pane

    HKEY_CLASSES_ROOT\FirefoxURL\shell\open\ddeexec

    Now you need to Double click on the Default REG_SZ registry value from right hand side, which should have a value of “”%1?,,0,0,,,,”. Delete that value and leave it blank.

    Close and exit registry editor

    …and now I no longer get the error message when I click a link from an e-mail but nothing else happens either. Is there another step or something else I need to do?

    Thanks in advance.
