I use Violentmonkey because it was suggested for installing the AAK-Cont userscript. It works really well in Firefox and Nightly for the desktop but for Android it's a slightly different story. The add-on still works in Android, it installs userscripts normally and works normally, but there is no easily accessible dashboard! You need to do this thing where you modify the url so it ends in html to access the dashboard. I'm giving this five stars despite the small problem I've described because this is still a great userscript manager and I hope it improves.
