Custom Cursor is a classic middle-school browser tweak: low-stakes aesthetic customization that makes Chrome feel a little more personal. It is light fun on the surface, letting kids swap out a boring arrow for a pixelated sword, a cat, or a cartoon sprite.

The main issue isn't the content—though the 12,000-item library has plenty of mature game and show references—it's browser permissions. Extensions like this require broad access to operate across websites, which isn't ideal on a shared or sensitive computer.

If your kid wants a custom pointer on a managed school or personal device, it works fine, but keep an eye on permission pop-ups and keep it off devices used for sensitive personal accounts.
