Thunderbird 24.6.0 suddenly stops accepting keyboard input in the middle of typing a message

On a system running Debian Testing (kernel version 3.13.10-1), at times Thunderbird 24.6.0 suddenly stops accepting keyboard input in the middle of typing a message. Some times, it will not accept keyboard input from the time a new message window opens (both from click Write or Reply).

Regardless of when the problem starts, I can still copy text from another source and paste it into the message, and I can still send the message.

Sometimes, the problem will clear up itself after a few minutes, meaning I can suddenly start typing in the open message window, but sometimes not, and I will have to close the message window and restart Thunderbird or reboot the system.

Check if any other programs is causing a high CPU load when this happens.

The System Monitor showed a processor load around 30%, and a memory usage around 40%

Try 'top' in a terminal window.

Is that at the time when Thunderbird is showing the problem?

Yes - I had an open message window that was not accepting keyboard input when I ran the top command.
