The file selector uploads files, it isn't comparable to a plain text box, I don't see why you're even using that argument.
It's changing the behavior of the file input box drastically, so it's very comparable to drastically changing the behavior of the plain text box for some potential exploits.
A site exploiting the file input box to trick you into uploading files in disguise of a normal text input is comparable to a site exploiting the password text input to trick you into entering your password in disguise of an online banking site. So Firefox "fixing" the file input box by completely disabling the text input, it's indeed comparable to "fixing" the password text box by requiring you first scan through the URL to prevent phishing.
They are both examples of over-reactions against some "security holes", one is already implemented in Firefox 3, the other hypothetical, but both are at the same level of absurdity, both are "let's fix a security hole by a drastic measure that greatly reduces the usability, while other much less drastic and more user-friendly alternatives are clearly available". That's why I'm using this argument. There's no good reason behind this file input "fix", just like there'd be no good reason to disable password input box until a full scan of URL.

And just because there are multiple ways to do it (like through Flash), doesn't mean we shouldn't bother fixing any of them ("I was going to lock my door, but then I noticed my window was open, so I left my door unlocked").
The point is that such drastic "fix" leads to great usability problems, in the name of "fixing" a "security hole" which it doesn't patch up anyway. It's like giving your door a complex lock that takes hours to open, but leaving the windows with a normal lock, so the legal inhabitants of the house has to spend hours to enter their own home, while a real thief can still enter the house easily under minutes, is just not logical.
Not to mention when they have enforced such drastical measures against the file input box with no option to turn it off, but give easy options to turn off the anti-phishing and anti-malware features, it's simply ridiculous and shows a severe lack of consistency in their logic and reasoning regarding "security".
