Does anyone know why FireFox is so fast while others are so slow?
I loved internet explorer for many years. Then when I tried a new browser to see if my website worked with it I found out that it was faster/more reliable. It's the sex!
If you want technical jargon, it's because it parses information more efficiently. In laymans terms, it's because it interprets the information on webpages much more efficiently.
The primary difference in terms of speed between IE and Firefox is in how they deal with standards for writing code for webpages. There are a set of standards that web designers are supposed to follow (set forth by the World Wide Web Consortium) that IE blatantly ignores (although the new IE is barely compliant), and Firefox is very good at finding the compliant code and rendering it. IE has traditionally looked for code that complied with Microsofts standards, which is why from a web design standpoint, IE has always been a nightmare.
