[Feature request] Visit domain names as if they were https:// URIs

[TLATER]

Hi, thanks for this neat app :)

I'd love to be able to browse to websites without typing https://, since that's quite tedious.

Of course that makes heuristics more complex, but anything that contains a TLD is probably intended to be a URL. I imagine it'd be rare for that to give false positives.

Combined with #178 that would basically make this a conveniently accessible Firefox URL bar with more flexibility and app access to me :)
