What is the problem with font rendering?

Question

Google Chrome

Faced with the fact that for some reason the fonts began to render poorly and I can not find the problem.
I screw the font with google fonts in html. In chrome (x64) everything is gorgeous. And in firefox and ie11 like this i.imgur.com/fQjOvlg.png
I use Win7 x64, the video card is built-in intel. Font smoothing is enabled in system settings. The ClearType setting does not affect the result.
Where to dig a problem? On the computers of the colleagues everything is in order.
