Update
// @require https://code.jquery.com/jquery-3.5.1.min.js
so now it is working in MACOS Safari

@wikrie May check out my vanilla-js version without the jQuerry dependency.

@stackcoder thanks for your work but your version is also not working with Safari under MAcOS, so I still use my old version. if you can find a running version for Safari that would be a major upgrade.

I assume you did add the code in "Userscripts" and saved it and it shows as activated?
The button only shows when editing an advertisement.

@mastermns yes of course the general usage and activation of userscript is clear. But the button will not be shown under edit page. In the past the button appears after changing the require link from http to https but nowadays it will not be shown. Don’t know why.

I try it again right now and now the button is there, did not change anything, sounds like a format issue of the script or something like that. thanks for your help @mastermns

I update the Script from ebay-kleinanzeigen to kleinanzeigne only.
