Oh right - but I looked up https://stocktwits.com/symbol/MZLA and it's from 2010 so I don't know if that's the new company but it says Mozilla.

Given that this is Stocktwits, I assume the page you linked was auto-generated after enough people used the cashtag ($-followed by Symbol) on Twitter.

It's the name of the new company meant to steward Thunderbird according to the post.
Why's Mozilla got a stock ticker if it isn't publicly traded?
