Unable to set action of opening image/jpeg in Firefox

I just want to open and view a jpg link in a firefox tab, but it instantly ask me if I want to save it or open it by other application. Fine. I go to Options - Applications to change the action of handling jpg. There are 2 kinds of jpeg, one is "JPEG Image (image/jpeg) and the other "JPEG Image (text/html). I can change the action of "text/html" to use Firefox as the default action, but for "image/jpeg", no matter how many times I tried, it just doesn't allow me to choose Firefox but other actions or applications. Precisely, I can choose Firefox in the "Select Helper Application", but after I clicked "OK", it reverted to the old action. I tried to restart Firefox and tried again, but no good at all. It frustrates me so bad.

Are you sure that these images are send with a proper MIME type for images and not with a generic MIME type that makes Firefox show the "Open with" dialog?

You can look at this extension:

You can look at this extension:

I don't understand what MIME type the image possesses. I need to point out that not all JPEG images have the same problem. For example, this can be opened in Firefox normally, but this just never yields.

I fiddled around with Applications of "JPEG Image (image/jpeg)" and now the problematic jpg file is always opened in "Windows Picture and Fax" and ignores any other action I have chosen.

That second image that gives a open with dialog is send as Content-Type: unknown/unknown and the first working image correctly as Content-Type: image/jpeg
So this is a problem with the configuration of the server and you would need the above mentioned extension to override this.

I installed the extension, but now Firefox always opens the JPEG in question in "Windows Picture and Fax Viewer" even if I've set "Always ask" in Applications. I think I've hit the bug of Firefox handling file of unknown MIME type.

Try to delete the mimeTypes.rdf file in the Firefox profile folder to reset all file actions.

Note that the extension will allow to open this image file in a Firefox tab as that is the purpose of this extension.

OK, finally solved, although not the way I have hoped. Undeniably it is a bug that should be fixed instead of relying on an extension.
