1) Site is in my Whitelist, so nothing here
2) When I disable NoScript, everything works fine (although my back is tickling, I hate JavaSctipt enabled
3) When all extensions except NoScript are disabled, FF still freezes.
4) All this started about month ago, I am not exactly sure but I know site worked for me before. I have no clue whether site change or NoScript update cause this inconvenience.
5) I just realised that the site went through Java applet update around time it stopped working for me. But as in previous point, I am not exactly sure.
I hope everything sorts out.
Thanks for good work.
