I got tired of fighting with Chrome and Safari over whether I'm allowed to read RSS files.
Just enter the URL in the dialog and click OK.
It even remembers the URL you can read the same file over and over.
Nice if you're trying to watch the file change.
PS: Drag it to the browser's chrome for easy access.
PPS: I look forward to the day when the big guys stop screwing with RSS. This item belongs in the trash.
PPPS: I am reminded that Firefox is guilty too.
