Stopped using firefox when they started to include closed source in the code.
Now I am using Pale Moon
Firefox uses closed source code now? I've read about Pale Moon and it seems like it is a lot less bloated. I haven't made the switch yet but I think I probably should look into doing it.
You should definitely check out Pale Moon
Also been using it for a while now. Plus, all my FF addons work in Pale Moon as well.
