Switched to Violentmonkey and couldn't be happier. The extension is incredibly fast, doesn't bloat the browser, and supports absolutely every userscript I need. The interface is clean and intuitive. A huge plus for being open-source. Highly recommended!

для фаерфокс не советую использовать. так как некоторые скрипты могут рандомно перестать работать. Например для стима. В остальном проблем у меня не было

It's time your change design UI to more modern 😶

Very good, my migration from Tampermonkey to Violentmonkey was seamless, no issues.
