Firefox keeps asking me to open/download PHP file when it used to be able to display properly.

I use to be able to view local PHP files normally in Firefox with the PHP parts not rendered while the HTML parts are. Now all it does is ask whether I want to open or save it.

I've tried editing FF options so that it previews in FF but it doesn't accept any changes. I've cleared my cache and all that. I've tried deleting the mimeTypes.rdf file thing but I can't even find the folder it's in. I've tried disabling/enabling "prompts.tab_modal.enabled" in about:config and restarting FF.

All are no-go solutions.

Web PHP pages are loading properly, this problem only comes when I'm trying to load local PHP files. I don't want to install XAMPP or PHP on my computer just to view local files as I never had this problem before.

In the meantime, I've installed Chrome and it's loading a simple local PHP file just fine whereas FF is asking me to save/download when opening the SAME file. Thanks in advance for any help.

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

  • Help > Troubleshooting Information > Profile Directory: Show Folder

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

Yup, deleting mimeTypes.rdf and re-starting did the trick this time. Thanks very much!

Also, on a somewhat related note, I cannot view mozillazine.org and any sub-domains under it in any browsers. This may be happening to other users as well?

It's always stuck at "Waiting for ..." or "Connecting to ..." and that's it. Then FF gives up with a "Server connection time-out" notice. Clearing cache and all that doesn't work because I was trying to view those pages before starting this topic.

Same here. Done all the cache deleting, There are no servers involved either. I have my scripts on a remote server ( own website ) when I try to access them ( try them ) FF asks me if I want to download them!!! It never used and I haven't altered anything.

If this is with PHP files then add this header:

<?php header('Content-Type: text/html; charset=utf-8'); ?>
