mimetypes.rdf corruption

more options

I am always presented with a Launch Application dialog box that asks me if I want to allow iTunes to open up itms and itmss links. I do -- I really, really do. I click the checkbox to make that choice permanent. The links then open normally in iTunes.

But, I get asked every time.

I see that the entries for itms and itmss in my mimetypes.rdf are defective -- they are missing the closing /RDF:Description entry (at least -- maybe other stuff is missing, too?):

<RDF:Description RDF:about="urn:scheme:handler:itms"

                  NC:useSystemDefault="true"
                  NC:alwaysAsk="false" />

I tried adding the missing entries to see if that would cause them to show up in the Options >> Applications list, but no go.

Not a huge problem, but I prob have to click through the Launch App dialog 15-20 times per week. I'm hoping there is an easy fix? Thank you!

Some tags are self-closing (consistent with the /> ending), so I'm not sure that anything actually is missing there. (I don't have iTunes on this system.)

Do you want to try having Firefox regenerate the file? Here's how:

Open your current Firefox settings (AKA Firefox profile) folder using

Help > Troubleshooting Information > "Show Folder" button

Switch back to Firefox and Exit

Pause while Firefox finishes its cleanup, then rename mimeTypes.rdf to something like mimeTypes.old

Restart Firefox. Hopefully now your preference will be implemented.

Thank you, jscher! While it's true that most of the entries do have the /RDF entry, I did find at least one other that doesn't that I didn't notice before.

In any case, following your instructions to whack the mimeTypes.rdf file worked perfectly. This time when I clicked the checkbox to make the change permanent, the following entry was added:

<RDF:Description RDF:about="urn:scheme:itms"

                  NC:value="itms">
   <NC:handlerProp RDF:resource="urn:scheme:handler:itms"/>

Seems to work fine now. Thanks again!
