"Failed to execute child process (input/output error)"

[EPT]

Binary package hint: firefox

I don't know what is exactly going on but my Ubuntu crashed at least three times a day now. After I changed to Gutsy Gibbon. When it happens I can't open any programs or do anything any more. Every time I try to open some program it just says "Failed to execute child process NameOfTheProgram (input/output error)" When I try to restart the computer it stucks to closing process "EXT3-fs error (device sda1): etx3_get_inode_loc: unable to read inode block etc etc.

Sorry but Firefox-2 is getting near EOS and they wont be fixing anything but major issues security issues mainly. Please try to reproduce this with Firefox-3.0 if you can reproduce this bug please click on Help > Report a problem and file the bug that way. This does not mean that it wasn't already fixed.

I am wondering how did you end up with firefox causing this issue?
