Imported Two Different Modules and have same Zoom Issue

Hello, I am a brand new Foundry and Forge user. I have two adventure modules, one free and one premium. In each of the modules, when I go to a scene it shows up zoomed in to a normal view. When I zoom all the way out, I can only zoom in very slightly when on Forge. When using Foundry on my PC, I can zoom in and out normally.

The modules are:
Adventure: The Black Hollow Artifact
the-island-adventure

I haven’t noticed this problem when using a world with no imported adventures.

Sorry, I am wrong. I’m having the same zoom issue in my sandbox world with no modules imported.

More information:
To clarify, I was wrong about it happening only with a module but it is still true that it happens only on The Forge and not when I run Foundry locally.
The specific zoom behavior is that when I zoom all the way out, it appears that the canvas is slightly smaller than the window. When I try to zoom in again, it zooms in until the canvas exactly fits inside the window, then stops.
I am using Firefox.
The Firefox tab zoom setting is 100%.
I am using a 4k monitor and in the Windows Display Settings, I have scale set to the recommended 150%.
The Foundry on Forge UI Scale is at the default value of 1.

I found out that zoom works in Chrome. It will do as a workaround but I hope sometime zoom will work properly in Firefox as well.
