Why does Firefox say that all .ZIP files are Google Gadgets?

more options

Whenever I open a file of MIME type application/zip from a website, Firefox says that I have chosen to open a file "which is a: Google Gadget."

I had the old Google Desktop on my old PC which used Gadgets, which have the extension .GG (not .ZIP), and I copied my profile with tons of my user info to my new PC.

How do I get Firefox to not say that all .ZIP files are Google Gadgets?

Did you try to delete the mimeTypes.rdf file in the Firefox Profile Folder?

Change the action for ZIP content type.

There was no action for "Compressed (zipped) Folder," so I made it Explorer -- same results.

My Firefox seems to think that, as shown if I select "Use other..."

  • application/zip is a Google Gadget and
  • application/x-zip is a Compressed (zipped) Folder.

Both are designated with zip icons.

So ideally I want to fix application/zip in Firefox so that it's a ZIP file like normal.

You probably need to change that MIME type in the MIME database key in the Windows registry.

  • HKEY_CLASSES_ROOT\.zip
  • HKEY_CLASSES_ROOT\MIME\Database\Content Type

.zip is registered as content type application/x-zip-compressed.

In the MIME DB, application/x-zip-compressed and application/zip are both registered to extension .zip.

application/x-zip is not in either.

Thank you; that was it. Rather than delete, I was able to edit the following from...

  • NC:fileExtensions="gg"
  • NC:description="Google Gadget"

... to...

  • NC:fileExtensions="zip"
  • NC:description="Compressed (zipped) Folder"
