This is an error of the website, and it looks the same with current Firefox development builds ("Minefield").

Happens in Camino, too. The fact that it's broken with Minefield and working with Firefox 3.5 sort of suggests a UA sniffing issue, and the fact that spoofing Camino as the Firefox 2.0 UA string *works* pretty much proves it.

Summary: XML Parsing Error: not well-formed on XHTML page → ihelper-mts.ru -- XML Parsing Error: not well-formed on XHTML page; serves different (broken) content to non-"Firefox" browsers
Well, it's pretty weird, I can see zero differences in the page content if I save the page in FF35 and in Seamonkey 2.0b.
Ok, so it appears the site is serving different content type to the different browsers: for Firefox/3.5: Content-Type: text/html; charset=utf-8 for Seamonkey: Content-Type: application/xhtml+xml; charset=utf-8
Everything's working now.
