Sometimes I just need to look into the details of a PGP key that is provided in its “armored” form by some website (not everyone is publishing their keys to the keyservers).
Normally I would have to import that key to my keyring or save it into a file and use gnupg to visualize it (as it is described in this Stack Overflow answers).
To avoid this hassle I just created a simple page with a text area where you can paste the public key and it will display some basic information about it. Perhaps an extension would be a better approach, but for now this works for me.
