I just upgraded from 10.6 to 10.8 a few days ago. I notice that every now and then my file associations are reset on start-up. I get a message from chrome that it is no longer the default browser. My media files get associated to esoteric video editing software. I can't figure out what is causing this issue.

For example, I checked to see which of my browsers was the new default browser. To my surprise it was Safari - I say to my surprise, because I've never used safari. I use chrome for browsing and firefox for development. The same thing with my media files, they get associated to an application that I've never used.

I don't even know where to start looking.

Thanks in advance!

Try rebuilding the Launch Services database or looking at system.log (or all messages in Console). – user495470 Dec 3 '12 at 10:25
