I wish more people understood the importance of what you just said. Not even the tech community seems to.
Also, I presume the performance issues on OSX are a known issue. I'd love to read a plan for resolution for that. It can take 6 months, I'd feel better knowing it's a tangible goal that's being worked towards as opposed to "we're making improvements as we can".
Lastly, thanks for contributing to Firefox.
It's important that Mozilla does differentiate though. Firefox is the only browser that's made by a non-profit organization and puts your interests before business interests. Other browsers can't say that - they all have financial incentives and other agendas for you to use their product. Firefox provides choice so you have full control over your browsing experience.
