The version in Aur is outdated. I downloaded the current version from Floorp’s website but I couldn’t install it.

The maintainer updated the package 3 days ago, I think they’ll update it soon. I just want to know: Is it me, or is it difficult to install it.
This is a good chance to do some learning! Try building & installing from source. The AUR is just a bunch of scripts to do exactly that.
Once you can do that, try updating the PKGBUILD yourself.
Edit: the repo on github (or wherever the project is maintained) will have installation instructions. It will involve terminal commands, and you will likely need to have other stuff (dependencies) installed first.
