Copy Tab URL WE

Не работает со странной ошибкой "не смог записать в буфер". Как в том детском анекдоте - "ну не шмогла я, не шмогла". )))

Doesn't work for multiple tabs, selected by clicks with ctrl button. Works for current tab only (no right-click-menu on other tabs). Sometimes doesn't work at all (don't override clipboard content). Linux Mint 19, FF 66

windows notepad does not recognize the [[n]] newline instruction in the "copy all tabs custom format" in options. if i paste into notepad++, all the index numbers appear at the beginning of the line, with a blank line separating each url. but if i paste into windows notepad, the first index number, of course, appears at the beginning of a line, but all the following index numbers appear at various points horizontally EXCEPT the beginning of the line. this is true with text linky tool as well. is there a reason this add-on would use a designation ([[n]]) that the most basic text program does not acknowledge? i use notepad++ strictly for certain purposes and use windows notepad for everything else that doesn't require Word-level formality, so i'd like to be able to read the "all tabs info" clearly in notepad instead of the jumbled mess that currently results from the paste. i'll up my star rating if i can get either a solution or a confirmation that there is no solution. just looking for answers. thank you for your contribution as a developer.
