Using the HTML Validator for Firefox, I have found that every page I open has errors, not just the ones I have designed; why?
It was suggested that I submit the question here. I am using HTML Validator (HTML Tidy) on the Firefox browser to check my web page design. Every page I look at, ATT/Yahoo mail, my pages and this one too, have errors. The software is W3.org certified and available through Firefox. I can't figure out what is going on. Any Clues?

There can always be code that is meant for other browsers and that the validator doesn't recognizes.
What matters is what kind of errors you see and whether this are common mistakes or errors that should be fixed.
Did you also try the W3C validor for comparison?
Like cor-el said while coding there are codes meant for other browsers too so probably the validator does not recognize that code. Also the code could be written using versions less than HTML 5 and the validator must be working on HTML 5.
Hope this helps.
