Adobe Camera Raw grayed out in Bridge for formats other than RAW files.
I'm using the latest version of Bridge CC (9.0.3). The option to Open in Camera Raw is grayed out for jpg, png, tif. But, it works fine with raw nef files. It seems the problem came with the recent update as it used to work fine. I tried resetting preferences and installing recent older versions of Bridge 9, but the problem persists.
I had a similar experience with Bridge 10.0.4.157, but only for some jpg's. For me the problem was solved by selecting the jpg's and then 'Right Mouse Click / Purge Cache for Selection'. I was then able to 'Open in Camera Raw' directly from Bridge.
