Opening a browser and saving a bookmark

Hi all, when I’m on Mullvad + VPN, I never open any other browsers for fingerprinting protection.

Does opening Firefox and saving a bookmark (without going to the specific link) will make any sort of connections other then to Firefox’s servers for the automatic sync that happens in the background?

Edit: I think the answer is no and why can be found here: Fingerprinting question for Mullvad Browser
