using firefox 49 it has become awful:
first of all it opens links clicked at the end, not next to current tab, as before and tab selection has become larger, marking irrelevant areas,
I guess it's time for an update

edit: well, ok, but the new version sucks big time, while the old one worked like a charm, so I rolled back too, I don't care about electrolysis either, I'll disable it if I get a chance

It even works on Firefox 48.0 (the "uncompatible" sign isn't true, fix it pls)

unfortunately there is no ability to copy as a plain text
eg. if i set action: Copy Links to Clipboard and select links on this page
Clint Priest, Tommi Rautava and then paste them to excel or word instead url i get Clint Priest, Tommi Rautava.

i suggest add some hotkey or options to copy links as plain text so result after paste to excel would be plain text
