Why is Firefox 10 insisting on saving images (jpg, png,gif) as filename.extension.rb?

After I upgraded to Firefox 10, when I attempt to save images, for example, the firefox-54x62.png on this page, Firefox offers to save the image as "firefox-54x62.png.rb" with image type "PNG image"

Found the problem. It was not in the registry. One of the Selenium IDE formatters (I suspect the Ruby one from the extension being forced) was interfering with the save image process. Issue can be closed.

Thank you for the help and suggestions.

Try to delete the mimeTypes.rdf file in the Firefox Profile Folder.

You can use this button to go to the Firefox profile folder:

Did not appear to solve the problem. "Save image as..." still tries to tack an rb extension on everything. Tried three different sites.

Inspect the MIME database key with the registry editor (regedit.exe) and do a search for that MIME type (file extension) via Ctrl+F.
Be careful with editing the registry as there is no Undo possible: all changes are applied immediately.
You can export key(s) before making changes.
MIME Database : HKEY_CLASSES_ROOT\MIME\Database\Content Type

You can also check those file extension in the main HKEY_CLASSES_ROOT\ branch.
