Description Doran Moppert 2018-05-09 07:16:50 UTC

If a text string that happens to be a filename in the operating system's native format is dragged and dropped onto the addressbar the specified local file will be opened. This is contrary to policy and is what would happen if the string were the equivalent `file:` URL.
