Change default view

Currently, Firefox opens OBJ files as text. I want to send them to the Microsoft 3D Viewer which is the default application in Windows for these kinds of files. All I can do right now is right click on the file, save the file, then open with the 3D Viewer. I have gone to settings/General then down to applications and I can't add any files there. (Why not?) It doesn't matter if I choose to save or open files, the OBJ file still displays as text in Firefox. How do I get Firefox to send instead of display these files as text?

被選擇的解決方法

If both browsers think it's a text file, that's probably what the server is telling them. I don't suppose it's a site that would be willing to update the Content-Type sent with the files?

Hmm, I wonder how Firefox figured out that it's a text file?

Firefox normally follows the guidance of the server in the Content-Type header that is sent with the file. If a server is well configured, the Content-Type will be sensible, but some servers have a basic set of content types and then they fall back to text for everything else, which is sort of useless.

Option #1

You can try training Firefox to open the OBJ files using the Downloads list. Click the Downloads button on the toolbar, right-click the OBJ file you saved, then -- if it's available -- click Always Open Similar Files. This should trigger Firefox to add a new entry on the Settings page for whatever the server said the Content-Type was.

Option #2

If the server is sending a nonsense Content-Type, I have my add-on that can help. What it does it override the Content-Type based on the file extension. The .OBJ extension is not set up at install time, but you can add it using the method described on my page here:

It's the "Roll Your Own Content Type Overrides" section.

The add-on can be installed from:

This is a more complex solution than I am willing to do, but thank you very much. Where are the Firefox people? Why doesn't Firefox allow you to edit the disposition of files in options?

Yes, I tried that and it’s amazing nothing works. However, it does exactly the same thing in Bing. It’s a conspiracy. The only thing I’ve found is that I can right click on the file, use the “save as” selection, then open the file outside of Firefox.

Well, it’s my site, so I am willing to change it. :) I should have thought of this! Thanks.

Okay, there's either a central config file or .htaccess where you typically define the MIME-types per extension.

有幫助嗎?
