Upgraded to FF 26.0, now links don't work in MS Outlook. But work in IE9


Had FF as default browser. After upgrade to FF 26.0, can no longer link to website from email received in MS Outlook 2010. Get error msg that "needs to know what program to open xxxx"

    If able to copy hyperlink from right-click, can paste it into FF and then can open URL. But not all links allow copying. Tried repairing MS Office, updated Flash [again], tried safe mode.  No success

Changed default browser to IE 9.0 and links in Outlook emails work again.

Note - can also make FF work, if, in the errro msg box, choose to search for program to open link. FF does not appear in the drop down list but allows search for other programs. Firefox is on the list of ~40 programs. Choose Firefox and the link will open. Obviously this is not workable most of the time.

I'd promise to ask at answers.microsoft.com. Maybe they know something.

Turns out that Chrome works too - also fixes a little problem that I was having on Facebook withFireFox. Had a problem too on Candy Crush - Candy Crush [King] told me that they were optimized to use Chrome - There are things that I prefer about FireFox. But right now, there are too many glitches. So, for the moment, I have to switch to Chrome and/or IE9 [not my favorite].

Sometimes there is a problem with links launching in Firefox, but don't recall hearing about anyone getting that particular dialog before. If you are interested in troubleshooting further, I'll dig out my settings for comparison.

What was the problem with Candy Crush? If you notice problems on Facebook with embedded games, this often is related to the mixed content blocking feature. This article has more information: How does content that isn't secure affect my safety?
