I updated Firefox yesterday to 3.6.9. When I receive a URL link in an email within Outlook, I cannot open the link in Firefox. As I said in the question, when I click on the link, a Microsoft Office Outlook error message appears which states that a General failure has occurred in sending the command to the application (which is Firefox). I am using Office 2007 This did not occur prior to the upgrade of Firefox.

Found following articles that AVG also not compatible with FF4 update: Above link did stop General Failure message but then did system restore and problem is back. I'm going to try and revert to 3.6 cuz problem definitely started with FF4 update.

I was also having an issue with outlook and syncing my iPhone with iTunes new update so total mess.

This quick registry edit fixed it for me.

(Note: These instructions apply to Windows Vista and 7 only.)

1. Click Start, type regedit, and then press Enter.

2. Navigate to the following entry: HKEY_CLASSES_ROOT\FirefoxURL\shell\open\ddeexec

3. In the center pane, double-click the Default entry, then remove whatever value is there (it'll probably be a weird string of numbers and commas).

4. Click OK, then exit Regedit.

5. If Outlook and/or Firefox are open, close them, then restart them.

REGEDIT fix worked great for me; remember to restart both Outlook & Firefox.

Every single time that I have to do an update on Firefox I then have to go back into the regedit and follow the directions again in order to prevent this error. The issue should be corrected by Mozilla on their next update. To be honest, it is kind of annoying!! This has been an issue for several months, and I am tired of having to fix their mistakes! MOZILLA!!! PLEASE FIX THIS ISSUE!!!
