Answer:
my answer is NO
Firefox made me mad. I still miss the old mozilla. you can type and Google at address bar by pressing down after you type, then press Enter. Firefox doesnt has this feature. Thus we search bar which wasted space
To close tab in firefox, you have to point you mouse on small [x] button on each tab. In mozilla there is only one [x] button for all tab, it close current tab.
That's all i miss about it

Firefox is prey to websites that open pop ups and new windows, even if you check the boxes not to allow these. Furthermore, these new windows are often "sticky", that is, they will not allow you to close them or use your back button without clicking a button on the website. This makes Firefox less secure than SeaMonkey.
