If an Ubuntu user downloads a Firefox nightly, it identifies itself as running on Linux, but not on Ubuntu, making web statistics less valuable to everyone.

Reproducible: Always

Steps to Reproduce:
1. Download Firefox for 'linux'
2. execute it somehow
3. go to whatsmyuseragent.com/
Actual Results:
It says I'm on Linux

Expected Results:
It should have identified my OS as Ubuntu Lucid (32 bit Intel) by running and parsing uname on first run.
