Works for me - Mozilla/5.0 (X11; Linux x86_64; rv:26.0) Gecko/20100101 Firefox/26.0 and Mozilla/5.0 (X11; Linux x86_64; rv:23.0) Gecko/20100101 Firefox/23.0
WFM with firefox-23.0.1.en-US.linux64 with hardware acceleration blocked by Firefox. Does it happen also if you disable hardware acceleration (Preferences → Advanced → General)? If it hangs (freezes), try killing it using "kill" or "killall" with the -ILL option; that usually makes the crashreporter start.
I have got an driver today and after that i can't reproduce this bug. Sorry for the noise.
Thanks. I don't know, maybe it could still be blocked in a new ESR build or something.
I forgot a word: "I have got an *update* driver today
