Based on Linkify Plus. Turn plain text URLs into links.
Since Opera now is based on Chromium, it should be compatible.
I've refreshed pages, and restarted the browser and haven't had much luck.
I tried to install the script on Opera. It seems that the script can work correctly with Tampermonkey v4.7.44, which is the latest version on Chrome Web Store. It doesn't work with Tampermonkey v4.2.5291, which is the version on addons.opera.com.
Opera compatibility?
Is there a chance this might happen?
