The font in firefox under linux is not rendered correctly. How to fix?

Question

linux

Xubuntu 14.10\firefox 35\compiz. Turning anti-aliasing on and off and changing dpi do nothing. The letters are still overlapping. The font itself is worth it.

Answer 1

Previously, ttf-mscorefonts solved the problem.

Answer 2

Yes, FF on Linux has problems not only with fonts.
Try a little letter-spacing, barely noticeable. ON FF, this property is slightly exaggerated compared to other browsers.
