Installing all the needed Firebase packages through the Package Manager instead of importing the .unitypackage files solved this for me. Some of my packages had been installed through the manager and some of them had been installed through importing, which apparently was causing some sort of dependency mess.

Go to your Package Manager (Window -> Package Manager) and search for Firebase. Make sure that the "All Packages" option is selected in the dropdown at the top-left. If any of the packages that you need is not marked as installed in the manager, install it.

If you get some error about GUID conflicts after reinstalling packages, just remove the conflicted files in the Assets folder and leave the Packages folder ones.
