So simple, yet so useful

it does not work, for me. march15: now i see that if link is normal, it does not show anything. but target=_blank links are shown with tooltip.

Please add "Show hovering URL" as a new feature, it will make the extension 100% better.
It's a little bit pointless when those icons tells you the link is external and you need to move your eye every single time to bottom side of the browser and making sure the link is safe to go.

I would like to know what are Advanced Preferences about...

Excellent. Just a little incompatibility with "Dark background and Light Text": The background of the box is no longer displayed.
Could you fix ? Thank You.

I have been using the add-on for a long time and found it to be very useful. There is, however, at least one issue with the new version (2.0.0). The link icon that pops up doesn't vanish any more when the page is printed (using a "print" link in the webpage itself), but remains visible on the printed page.

I think there was an option to turn off the printing of the icon in the old version of LinkAlert, but I cannot find it in the option menu of version 2.0.0 any more.

To Dev: Change 'realtive' to 'relative' in ./src/mousebox.js or examine your console for errors. (v 2.0.0)
Please.

Have used and enjoyed this extension since a long time ago. However, after porting it it ceased to work altogether on FF developer, whereas it still functioned as a legacy add-on before the latest update.

thank you!!

Thanks for porting it! The extension got even better!

(doesn't seem to work in nightly 58.0 at the moment, however?)
