Suppress Error Popup

[efefefe]

Hi,
This is very annoying because it prevents both my mail client and YPops from going forward unless this dialog is closed. How can I disable it for any errors that might happen? I don't want to see YPop errors at all, my mail client dialog is sufficient for me.
By the way, this error popup always displays blank page so there's no use in it anyway.
Thanks

I have the same problem with server timeouts in Thunderbird. And when I get a Thunderbird timeout error message, Firefox appears to freeze.I

I actually increased the server timeouts to a huge 1800, hoping that would eliminate the error messages, but no dice. I have over 20 email accounts (don't ask) on one server. This seems to be a relatively new problem, and is driving me nuts.
