I've been quite happy using Firefox for all personal and most web development work. Unfortunately though we've had to recommend Chrome to users of our web application since Firefox doesn't support speech recognition..
To catch up I think Firefox needs
- More funding - I think large tech companies should donate heavily to avoid a chrome monopoly..
- Perhaps more focus on core browser features like speech instead of various side projects? (like Firefox Color and Price Wise.. though I must admit I really like Screenshots).
