fireftp VS cookie-garden-helper

I had it working fine on Waterfox, then I made the mistake of upgrading to new version. My fireftp was gone. I downloaded the zip file from the fireftp.net site and tried to install the extension on the new Waterfox but kept getting that it couldn't install because it was corrupt. I cloned the github repo, https://github.com/mimecuvalo/fireftp and followed the instructions. I have the repo in a local github folder, but I can't figure out how to use it. I tried opening it in visual studio code and then on live server, but it just browses and doesn't run any javascript file. Do I have to run an npm install? Where would it get the dependencies? I don't see any package.json file or similar. This was my favorite ftp client ever.

So I'm looking at the garden and the stock market mods. I'll focus on just one, the garden helper mod. Can be found here: https://github.com/yannprada/cookie-garden-helper

The garden and the stock market are the two areas where I don't feel bad using a little automation. For the garden I use Garden Helper. I plant chocoroot and bakeberries in the 2 species mutation layout and use wood chips. Garden Helper replants the chocoroot and bakeberries, removes weeds, and autoharvests plants before they die. You end up with tons of free queenbeets and the occasional duketater.
