My search results were showing Firefish th CRM/Recruiting software as well (used DDG).
Seems like the devs might want to consider changing the project name or work on SEO.
Edit: changed my search to "Firefish Open Source" and it produced results related to OPs comment.
If you don't need/want Bitlocker simply boot into Windows go into the bitlocker settings and turn off bitlocker (dont use suspend as bitlocker will be re-enabled the next time you boot into Windows). You will need to wait for Bitlocker to decrypt before shutting down - there will be a small status window that appears showing the progress and it shouldn't take too long.
