Об этом расширении

Text MultiCopy is a tiny extension that allows saving of texts, multiple times, from multiple locations, and then pasting all to the Clipboard. It does not interfere with normal copy/paste functions until data is copied to clipboard. It is a handy tool for gathering references for an article or university thesis/dissertation.

Note: None of my extensions contain any tracking, advertising or privacy infringement.
