New Mail Alert Config Extension [nmalertconfig]

I had a gripe about Mozilla Thunderbird 2.0 . I have been using it since beta days and a new “feature” has been bugging me, so I fixed it with my extension. Basically this extension allows you to configure whether to see a new mail alert (popup) per account instead of just a global setting.

By default, [i.e. if you don’t specify the setting in Tools->Accounts->Server Settings -> Show new mail alerts] it will show the alert. So if you want to disable the new mail alert for an account you have to uncheck this box. From the limited testing I have been able to do [On Windows XP / Thunderbird 2.0b2 and Thunderbird 2.0.0], it works fairly well. I will submit this to Mozilla Addons and but I think it will on the public site for “quite some time”. Meanwhile it is available here for downloads and updates. You may try it at your own risk, I will try my best to support any user.
