Firefox and Russian fonts

They say that many have problems with Russian fonts in Firefox under MacOS. I seem to have them too. But I solved them very quickly. Google helped.
For those who are too lazy to look, I will tell you how to solve the problem.

Download this archive here (1.7Mb, rapidshare.com). Unpack and copy them to ~ / Library / Fonts.
then open the Font Book; Click Apple + 3 and enter the text in Russian.

font preview, with Cyrillic
Select Computer in the Collection and look for fonts that have a period to the right of the name. the point suggests that there is a conflict.

This is how dots and fonts look without Cyrillic
go through each font, and disable the font that did not show the Russian text in the preview window.

all is ready

It helped me. Did it help you?
