Firefox Vs Iinternet Explorer

Internet Explorer 7:- may end up on a slightly higher security-level, and may not add just as much “fun” for the average user as previous versions do. Based on how some of that hightened security will be achieved – by passing site-addresses on to Microsoft(?) for clearance, I don't think I will concider IE7 as anywhere near secure enough for serious use.

Firefox:- has a much better reputation when it comes to built-in security, and seems to keep up a pretty good defense as new and improved versions arrive. Firefox also has the basic preventive measures against unwanted content/junk in place, so fewer annoyances can be expected while surfing.

use firefox Extensions to make easer your work and get more features..
try these...

1. IE tab:- to get the features from IE(its use for Unicode sides)
   
2. downthemAll :- to download files faster
   
3. Tamilkey, Adhiyan:- to type in tamil Unicode in chat or mail....
4. Cooliris Previews:- to see the link pages without click or go into that page
5. many more..
   

it is better to use portable firefox on your pen.
