Trying to access facebook I was suddenly told I was trying to download a PHP file, and what should I do with it. I said, open it with Firefox and then a hundred new, blank tabs opened... Solution follows.
There's quite a lot of stuff on the web about this issue, there seems to be some complaint about firefox's mime-type handling, corrupt mimeTypes.rdf files, etc.
1. Type about:config into the address bar.
2. Find the preference browser.download.pluginOverrideTypes and, if it is present, right-click on it and select reset.
3. Find the preference plugin.disable_full_page_plugin_for_types and, if it is present, right-click on it and select reset.
4. Exit the browser, then open the profile folder (Windows 2000/XP/Vista users, read this for help finding it).
5. Delete (or rename) the file mimeTypes.rdf. Caution: There is also a mimeTypes.rdf file in the program folder. Do not delete it by mistake.
There are links on the page itself to help you do this, find the correct folders etc. Note that on the about:config page, search doesn't work, so you should scroll to find the entries.
Now go into Tools -> Options -> File Types -> Manage
You should have a list of file types and how firefox will deal with them. Scroll through and find PHP. If there is an entry, delete it.
CommentFirefox won't open PHP pages suddenly comment by Jack YanHits | Last Modified 2009-07-27 Ralph, I get this error all the time but I do not have the two fields you mention in my about:config. The weird thing is if I wait a few hours, I can access the page, and I know the page itself has not been changed. Thanks for posting this, though, as itís way more helpful than the pages I have so far seen on the ínet about this very common issue.
CommentFirefox won't open PHP pages suddenly comment by Jack YanHits | Last Modified 2009-12-20 Hi there: your clues really helped. As Firefox has removed those fields in about:config and no longer allows file type deletions, it might seem that the above advice doesnít apply. Not so: the mimeTypes.rdf advice still does. Hereís what I did, taking your lead, and using Firefox 3.0.16:
