I have tested Boris's build
The results are:
chrome is broken in large part
Mail.ru mail interface is broken
Gmail is broken
google docs is broken
peacekeeper is not broken
3 russian it news portals are not broken (UI is OK, on the one sending the comment worked with minor bug in UI, but when I tried one more time, it disappeared, so maybe not 3 but 2)
Google is partly broken
Microsoft.com is not broken
mail.live.com is broken
mail.yandex.ru is broken
reddit is not broken (I havent tested send)
facebook is broken
Probably this is because of JQuery, my projects (I don't use JQuery in them) work fine.
