Actually the problem arised on a PC with an old Cirrud Logic Video card with a small memory, so the display is set to 16bit. If I put the display to 24bit I must pass to a low resolution of 800x600, and the crash does not occur. With 16bit 1024x768 the command:
XLIB_SKIP_ARGB_VISUALS=1 firefox effectively avoids the crash. -- Crash when opening an URL which need Macromedia Flash https://launchpad.net/bugs/71062 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
