Greasy Fork is available in English.
Open links in new tab. Ctrl-click or Middle-click loads it in background
As far as I understand this feature is already implemented in all userscript extensions: you can exclude the current site from the userscript in the extension's popup menu or in the editor for the script.
The userscript works very well for my daily applications, but it also opens some links that are not meant to be links (Sorry, my English is bad) like the menu next to each message, the script would open the menu in a new tab, causing inconvenience for the user. Please add a button like in the Mouseover Popup Image Viewer, add a button in the Tampermonkey (or Violentmonkey) menu that lets the user choose if he/she wants the script to be active in the website. Thank you.
