An open-source add-on for previewing, searching, and collecting links to read later in a popup window. Source code available in releases or branches.
Due to browser add-on limitations, this can't be done directly by the add-on. However, you can use third-party software like PowerToys to achieve this. Don't forget to uncheck "Close popup when origin window is focused" on the settings page.
Try disabling other add-ons to see if the issue persists. If you're using Edge, also check edge://settings/superDragDrop. If the problem continues, please create an issue.
