When I paste anything on Gmail these two little squares will show up:
Looks like two characters, I can cut them as I can do with any text, but when I paste there's nothing to paste. Any idea what this is?
By the way, I use Boomerang for Gmail, not sure if it's related.
–update:
It shows up always in the end of the mail, after the signature, even if I paste something in the beginning of the text.

It was indeed an issue with Boomerang on Firefox.
Thanks to Michael Hoffman for letting us know about the issue. We released a fix for this last week. If you are still seeing this, make sure you have the latest version and reload Gmail after clearing cache.
