Baikal for calendar, todo and contact syncing

But if you try to load a local resource as localhost in Firefox…

For the sake of completeness:

Firefox contains a security patch which restricts the kinds of files that pages can load (and methods of loading) when you open them from a file:// URL. This change was made to prevent exfiltration of valuable data within reach of a local page, as demonstrated in an available exploit.

Insecure, but fast fix, if you don’t want to install a local webserver:

about:config
security.fileuri.strict_origin_policy
change to false
