After successfully downloading Thunderbird several times (my browser is Firefox), the only functioning option provided is to make a donation. That is, it's telling me I must make at least a $5 donation in order to proceed to setting up a Thunderbird account. This despite clear statements on the website that donations are not required in order to use Thunderbird. There is no way to skip this step. After closing the donate window, I'm taken to a nearly-blank screen with absolutely no functioning features on it other than a link that leads to multiple, useless articles about who knows what. Please fix the site and advise how to proceed without further roadblocks.
