This is mostly FYI, but if anyone has any additional clue to add, I'm all ears.
Firefox 3.6.x (FrontMotion MSI packaging)
Windows XP SP3
Internet Explorer 6.0
Outlook 2003
We have had Firefox deployed to select computers, via the FrontMotion MSI, for some time now. We recently upgraded from 3.6.13 to 3.6.17. Post-deployment, we got trouble reports from a few users. In Outlook, when they clicked a hyperlink in any HTML message, they were prompted with a common dialog entitled "Locate Link Browser", looking for files of type "Executable Files". All affected users (so far) have had Firefox deployed to their computers but were not using it as their default browser.
MSKB 821692 gave us the clue we needed, even though it wasn't quite an exact match. The file association for several URL protocol handlers were horked. The shell action "open" all had their "Application used to perform this action" fields set to:
Code: Select all
"" -nohomeCode: Select all
"C:\Program Files\Internet Explorer\iexplore.exe" -nohomeThis affected the following URL handlers (they show with a file extension of "(NONE)" in the Windows Explorer "Folder Options" GUI):
- URL:HyperText Transfer Protocol
- URL:HyperText Transfer Protocol with Privacy
- URL:File Transfer Protocol
- URL:Gopher Protocol
Code: Select all
HKEY_CLASSES_ROOT\HTTP\shell\open\commandI note that we deploy Firefox to not automatically become the default browser. We do have some users (myself included) who elect to make it the default browser, though. On those computers (the ones using Firefox as the default browser) there were no apparent problems. On mine, at least, the URL handler is:
Code: Select all
"C:\Program Files\Mozilla Firefox\firefox.exe" -requestPending -osint -url "%1"Hope this helps,
