** Description changed: When starting up either Firefox or Thunderbird,the system freezes. First the cursor usually freezes and no input is possible, but the desktop display remains, sometimes for a few seconds. Then a pattern of horizontal bars appears on the screen. The bars are about two or three inches wide and about an eighth of an inch high, in various shades of color or black and white. Each thin horizontal bar looks like it is a sliver copied from the display picture that existed on the screen before the crash. System almost always crashes when I click on an e-mail link in Thunderbird, as soon as the system attempts to start up the Firefox browser. System frequently crashes if I attempt to start up either Firefox or Thunderbird after I have previously run the other application. So, if I run Thunderbird and close it, then try to run Firefox, a crash occurs. Or if I run Firefox and close it, then try to run Thunderbird, I get a crash. System occasionally crashes the first time I try to run either Firefox or Thunderbird, even when I have never opened either application previously during the session. Basically, I can only use either Firefox or Thunderbird once, or sometimes twice, per session, before the system freezes and requires a cold boot. However, the system sometimes crashes without opening Firefox/Thunderbird, please see comment 7 for more details. System crashed after leaving it for a few hours. The screen saver blanked out the screen by that time, I move the cursor, the application I had been using appeared briefly (it was a Sudoko game I had been playing a few hours earlier), then the lines appeared in its place and the system froze. Pressing Alt+SysRq+1 followed by Alt+SysRq+t does nothing. It is a total system freeze and requires a cold boot. Problem began after installing upgrade to Ubuntu 13.04 (raring).
