from my side ,, The firfox is the second best Browser ,, because google chrome have more security than firefox ,, although Mozilla doing updates and bug fixes but chrome is still the best from that side ..
i began to use Chrome 2 months ago .. really happy with it (faster than FF) but i dont know why .. when i want to see my javascript code (affiliate cpa), it doesn't show on chrome but works on FF if i didn't have that problem i would be using only chrome now
I love Firefox. It does everything I want it to do, and it has great addons for web developers. Firebug in particular is a good'n
For me, it's still the best browser for SEO purposes. Which is suited to plugins/addons that will make your work easier.
firefox is very good browser and we feel good experience with firefox. we recommend people to used firefox.
I think that the best or not depends on the person wearing it. Myself use Mozilla for browsing purposes, but if I would use the Internet to download, I use Internet Exploler.
