Nothing helped.

This is specific to Cyrillic-script pages/locales, and occurs because the default font names specified in Firefox preferences are the old "CY" variants of Times/Helvetica/Monaco, but these are no longer shipped with current versions of OS X.

See http://mxr.mozilla.org/mozilla-central/source/modules/libpref/src/init/all.js#2110 and following.

You can fix the problem locally by selecting appropriate fonts in the Preferences dialog, but obviously we should update the initial defaults. With standard Unicode-based fonts now available on the platform, the script-specific "CY" fonts from classic Mac OS are obsolete.

Attachment: patch, v1 - update Cyrillic font prefs for OS X

I don't have a 10.7 system to test this on, but it resolves the problem for me on 10.6 at least.

Interestingly, the "Charcoal CY" font is still present on 10.6. Can someone confirm whether it is also shipped on 10.7?

Yes, I see Charcoal CY, Geneva CY and Helvetica CY in the Font book,
but no other CY.

This seems a serious bug for the affected locales with a trivial fix.
Should it land on Aurora and Beta?

I have used the steps from the description in order to verify this and the text is rendered as expected.
