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?

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"
