Windows 10 home – you just named the #1 problem there. Microsoft is even blocking installation of open source software if it does not comply with Microsoft guidelines when running family safety.. this includes Firefox, Chrome. It ignores the obvious elephant being that filtering does not occur in the browser, it occurs on the connection, ie kernel – but Microsoft wants to push ‘Edge’.
That said, I use Thunderbird. I’ve connected it to Yahoo, Gmail, and Corporate networks. It does use an encrypted transfer from the mail server, which not all Mail browsers use. I do think that Thunderbird needs to look at how it does its software update though. Best method right now is manual, though it does have an automated one.
NOTE: I have not run it on Windows 10 home though. I have it running on Windows 7, 8, 8.1.
More on why Microsoft’s approach is probably doomed to failure (with respect to kid filtering):
