not for duplicate closing tags Rated 4 out of 5 stars
Duplicate closing tags will not show up in the code. It seems that this chart ignores duplicate tags it can not make a match to. Making it difficult to test errors.
Thought it was cool you can expand/collapse areas of the code that you want to ignore or see in detail.
****Does not work for 3.0, would like a new version please!!****
Known as Rendered Source
Firefox corrects the duplicate tags, not View Source Chart. See the description for more info.
