Tampermonkey scripts — readme.mlav.land

Scripts for the Tampermonkey plugin that run small Javascript programs on any website.

What is Tampermonkey?

Tampermonkey is a free browser extension that lets you run small JavaScript programs — called userscripts — on any website you visit. These scripts can modify, enhance, or automate webpages in ways the original site never intended, giving you full control over your browsing experience.

Why is it useful?

Customize any site — Remove ads, tweak layouts, or add dark mode to sites that don't offer one.
Automate repetitive tasks — Auto-fill forms, skip countdown timers, or simulate clicks so you don't have to.
Run your own scripts — Write JavaScript that runs automatically every time you open a specific page.
Access a huge library — Browse thousands of ready-made scripts on communities like Greasy Fork and OpenUserJS.
