Russian Firefox ?

Are you using Firefox in Russian, I have 2 other users reporting this issue in Russian only. It seems to be linked to the "-1" of a preference who is not recognized as number only in FF 16-17 in russian. Don't ask me why :-) Mail me to for more info. Thanks

Ps: I got this from another russian user:
tidy.options.accessibility-check had STRING type in my about:config :
tidy.options.accessibility-check string -1

So I reset it and restarted firefox

After restart I have this
tidy.options.accessibility-check integer -1

It worked !
