Nevertheless, the overall look and feel in firefox was improved somehow. Now I've updated mesa to 9.1.2 and kernel to 3.9.0 and these positive effects are preserved.

The situation is much better now than it was when I opened this bug: I don't have random huge screen corruptions in firefox both in thumbnails and during normal browsing. Though I can still trigger this issue and get corrupted page preview, it doesn't interfere with browsing. All other applications are unaffected.

Since, things are quite good now, maybe it is a good idea to enable back that optimizations? What do you think? It looks like I am the only one who has this issue:(
