How to install to a PC browser
Step 1. Scripts manager
To use scripts, first you need to install a scripts manager. My advice is Tampermonkey, since I use it too.
Tampermonkey install links for different browsers, choose yours:
Chrome / Vivaldi Opera Firefox Safari Microsoft Edge
Is your browser missing here? Maybe some link from above or Google would work for you
Step 2. Come back here
Refresh the page and press the green Install button that right above this description. A new tab from your scripts manager would open. Press the Install button there too.
Step 3. Check if it works
If it's not, post a discussion here about it to get it fixed
