Works for right-clicked links as well as for all links on the page. Detection of selected links doesn't seem to work, at least not on the site I tried it on. But I'm mostly interested in marking individual links as visited, so I'm quite happy with this extension.

Great addon, very fast compared to alternatives.

Does not seem to do anything at all. I even tried refreshing the page. Just another out of date extension I guess.

Does not work at all

exactly as needed. no extra permission used. BUT if you can add a function to Unvisit selected link, then will be perfect.

完美！Mark All as Read！

Used "Link Visitor" for a while and it became painfully slow when marking all link on page as visited. This add-on is fast and does exactly what I need it to do.

Does not work!!! I need something like this! But "Visited" is not compatible. I want the old Firefox!

This does not work in Firefox Quantum.

Works, but Firefox 56.0 either hangs or crashes. This happens 4 or 5 times a day, so I now keep it disabled until it's needed. Very frustrating.

doesn't work
