When browsing with Tor (I use The Browser Bundle) my friend e-mails me a .doc file, or a .pdf if I try to download it I get the message "An external application is needed which could compromise your identity." If I right click "save link as" the message still appears. This happens on any website if I try to download any file, .exe, a .zip, even a .jpg file this message appears. I don't understand why TOR is needing an external application? Is this a glitch? Is there any way to test if it is truly killing my anonymity? Any feedback is greatly appreciated!
