how to remove the small top margin, which appears only on the first page of printing
first i removed header and footer, and set the all margins to be found in about:config(Linux) or in Dialog (Windows) to zero.
On all html documents i get a little gap on the top of the first page, but not on the second one. The gap appears on paper print, on file print(PDF) and on preview - under firefox (17.0) for Linux and Windows. IE 8 on windows has other abnormalities, but equal top margin on all printed pages.
How can i remove this difference top margins between first page and the following once in firefox ?

It seems the difference is the default 8px margin on the body element, which only appears the first page. To remove it on a case-by-case basis, you could use a bookmarklet (a snippet of script you run by clicking a bookmark entry).
To remove it automatically on every page, you could use a style rule in userContent.css or in a Stylish rule. I haven't tested this rule very extensively, but something like this:
@media print{
body {margin-top:0 !important;}
}

Yes - the default margin-top in body is responsible for this behavior. Thanks for your solutions.
