Setting to change Firefox Sync Node & Self Hosting Firefox Sync Node

Please add the ability to easily choose the node URL when logging into Firefox Sync in Firefox browser

And the ability to self host your own Firefox sync node. By providing documentation on self hosting a node, a maintained bare metal installation and a maintained docker container.

This can allow people to choose weather to have their bookmarks and history synced with the official Mozilla Firefox Sync node, their own self hosted node, or a third party node that is hosted by someone else.

This will be a great feature to have for desktop and mobile versions of Firefox.

This is already supported.
