Mozilla Firefox is best Browser.
Following Features, though small, are very handy:
1. Add Ons:
Some addons like DownloadHelper are Epic for those who want to download videos, Images, Links, even Movies & Mp3s.
Adblock Plus: A nice add on for reducing/block Spam and Junk Advertisements.
2. Rich Options and Menus.
History Menu consists of
RESTORE Previous Session (Cool Feature if you accidentally closed your browser.)
Recently Closed Tabs
3. Smart Bookmark
By simply clicking Star icon you can add it to Bookmark
You can Import and Export Bookmarks.
4. Address bar Favicon
This is my favorite thing about Firefox. This come handy when your Right Clicks are disbled, and you want to downoald Image. Then Simply Click favicon and see types of media stored on your PC. And simply save it. Also see the Coockie and Certificate Info. VERY Handy & Quick.
5. Good size for Reload Button so you don't have to focus too much.
6. Right Click Highlight & Search Option with a number of search engines.
Very handy if you want to search google by highlighting and search.
7. Tabs can be moved as separate window and vice-versa.
8. You can Drag n drop Favicon to make a Quick access button for mostly visited sites, such as Yahoo answer.
9. Partial Downloads can be resumed.
10. Clear History by Hour, by week and Entirely.
11. Full screen support F11.
12. Very good support for Zooming in/out Pages by simply clicking Ctrl+ '+'
13. Very few times it crashes as compared to IE
14. It does not disables the Web page while saving, like IE does.
Firefox is better than Chrome for me because Chrome does not have Such Handy Features. I have to search for those when i need them. Google chromes philosophy of using less screen space is very less helpful to me.
