After recently stumbling my way into the settings-menu for
SessionSaver (the Firefox-plugin that saves sessions for when FF
either crashes or you close it) I noticed some strange dots in the
titlebar which look like this:

.. ::. .. : .:.. . ... 

They look like some variation of braille except that instead of using
2x3 dots it looks like a 4x2 system (if it even is a variation of
braille). If it was some sort of morse code then it would either spell
IGITLES or MUMEYTO depending on how you interpret the .s and :s, but
I've been unable to make any sense of either of these "words" or found
anything useful when running them through anagram generators.

Here's a screenshot of the menu:

I'm currently using version 0.2.1.031 of SessionSaver if that matters.

And thus my question is; What exactly do these dots mean?
