then please consider

Thanks for your help.

As you may know, in order for Tampermonkey to actually do something, you need userscripts. The new Userscript.Zone website can help you as it allows you to search for userscripts by URL, domain or search term. So give it a try!

A list of other script sources can be found here.

Below there is a short overview of some of Tampermonkey's key features. Maybe you'll find something useful. 🤓


Easy Script Access

popup menu

The Tampermonkey's popup is useful for quickly and easily managing installed userscripts. In some browsers you have to manually pin the icon to see it all the time. It allows users to enable or disable scripts, view the status of scripts, and start update checks without leaving the current page. This makes it easy for users to control the behavior of their installed userscripts and customize their browsing experience. Furthermore the number of running scripts is displayed as small number right at the extension icon near the address bar. ( video tutorial)

Tampermonkey's editor is OK, but you want to use your own? The solution is to enable file access and to @require the local copy of your script.

You can also try out the Tampermonkey Editors extension to edit the script at vscode.dev


If you're not happy with Tampermonkey (this is unlikely to happen, but who knows 😉), then you can remove it at the browser's extension page.
