This chrome extension is bare bones simple. It checks to see if a nexusmods download page is open and if it is, it clicks "Slow Download". Then closes the tab after 10 seconds.
After downloading the zip file, extract it to your desired location.
Open chrome and navigate to extensions (put chrome://extensions in your address bar), from there, in the top right corner there is a toggle to turn on developer mode.
after that in the opposite corner click on "Load Unpacked", and select the extracted folder.
Once you've selected the extension folder, it should automatically load the exentsion and you should see it under "All Extensions" on the same page.
Once you've confirmed the extension is loaded, navigate to any nexusmods page, find a mod, go to files and click manual download. If it's working it should automatically initialize the slow download.
