The bug showed up again today. The whole system has started to crash
consistently whenever I try to start up Firefox or Thunderbird. Yet it
worked well all day, for about eight hours steady. And I was using
Firefox frequently during the day. I also used Thunderbird this morning.
It is difficult to remember what I did just before it started to crash again,
but I think I did the following:
loaded the font viewer program,
uninstalled Abiword,
downloaded the Xubuntu restricted extras,
installed a few fonts with the font viewer, and
edited some files in both LibreOffice and gedit.
I doubt if any of these things could cause it to start crashing again.
But something did.

Title:
System usually crashes when starting Firefox and/or Thunderbird
Status in “linux” package in Ubuntu:
Incomplete
Bug description:
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).
