On Linux (both Xorg and Wayland), selecting text with mouse or keyboard sends the selected text to PRIMARY selection.
This addon sends mouse selected text to regular clipboard:
> on mouseup, send document.getSelection() to navigator.clipboard.
It is only a 4 lines content_script!
* after install of module, you must reload any existing pages before selecting. Otherwise it will NOT work.
* do not test it on
https://addons.mozilla.org/, it will not work
NB: this is mostly
https://addons.mozilla.org/fr/firefox/addon/copy-on-select/ with a github a link to see the source code!
NB: it does the same thing as VSCode
