I have a "classic" install of ubuntu 12.04.1 LTS 64 bits, with the ubuntu-restricted extras 57 installed. All updates done.

When loading this page from a daily news papers from Firefox 18:

http://www.leparisien.fr/societe/video-la-lecon-de-conduite-sur-neige-de-bernard-darniche-20-01-2013-2496573.php

The whole system becomes unresponsive and like frozen.

I can't break it nor gain control again through the: ctrl alt del.

I have to turn it off the hard way (electric reset!).

I suspect a bad javascript on the page.

  • Is there a better way to gain control back?

  • Is there a better combination of keys to kill the unresponsive application?

  • Is this a firefox or an ubuntu bug to report?

Thanks in advance for your help.

No idea about the cause - did you try with another browser (eg. Chromium)? I just opened it in Chromium - system load increased dramatically. –  guntbert Jan 20 '13 at 20:52
    
Just installed Google Chrome Version 24.0.1312.52. The page loads fine and Ubuntu 12.04.1 is responsive. Looks like a Mozilla Firefox or an Adobe Falsh issue isn't it? But I am still interested in knowing how to kill the dirty app or process that is freezing the machine. –  user124750 Jan 20 '13 at 21:10
    
It seems so - report it as a firefox bug. –  guntbert Jan 20 '13 at 21:11
    
Just reported it to Mozilla. –  user124750 Jan 20 '13 at 22:11

  • One method (nearly as extreme as shutting off): altSysReqK restarts the X Server (and kills your complete session of course)
  • If you are able to open a terminal session (ctrlaltT)
    try pkill firefox or even pkill -9 firefox.
  • If you are able to open a virtual terminal (ctrlaltF1)
    you can login there (you don't see any feedback when typing your password), and then you can use pkill like above.

Thanks for your help. (ctrlaltT) brought the terminal window on top but I couldn't type anything, the system (display) is frozen. Even the mouse cursor doesn't move anymore. –  user124750 Jan 20 '13 at 22:11
