FF is more forgiving with errors in html code.

If there is no image, you don't see that huge box with an "X" like you see in IE. FF displays nothing.

If you forget a closing tag or the end ">", FF generally guesses it correctly and the page will show up right.
We discovered a trademark infringement that displayed in FF and not IE because the image tag was improperly written without the closing ">".

FF came out with tabbed windows before IE and I like the way FF handles them.

I use phpMyAdmin and IE opens a database table I select from the left frame in a new tab! Thus, for each table, I get a new tabbed window. That adds up to several tabs when I need to go between several tables.
FF will open it in the right frame where it should be.

FF is getting more and more popular, especially in the UK and rest of Europe.

also firefox takes more RAM
and FF is not as fast depending on your profile."
And I'd like to see the benchmark data for this.

CAN SOMEONE REMOVE THE CURSE LANGUAGE RamyD has in his post, above?
