Description (please include examples/screenshots where applicable)

When in "Skip all redirects except for URLs" mode, when the extension skips a redirect that I need, I try to use the "Copy last skipped URL" feature but my clipboard just has whatever it previously had when I past into the "No-skip-urls-list".

This looks like a Firefox bug to me, there is an error for missing host permissions, but host permissions are not part of the webextension version Skip Redirect is built with.
