Which is very lenient browser for coding? Whether IE or Firefox?Which would accept even junk CSS /javascript coding?
Wanting a "lenient" browser is something for amateurs. You want a browser that can read your mind and display what you're thinking because you are too lazy to learn the proper way to write markup. You also want to rely on the browser to always guess correctly at what you are trying to do. Neither browser is any more "lenient" than the other. Learn to code, rookie.
