Do not inject the overlink popup into the page until a link is hovered over. This is to reduce breakage on sites that use javascript to (re)build the page immediately after the page is loaded, possibly trying to detect DOM tampering in the process. Of course, this workaround fails if the mouse is already over a link when the page is loaded (or is moved over a link too soon thereafter).

Remove web_accessible_resources for theoretical improvement of security and privacy.

Avoid security error messages in web console

Compensate for browser zoom level by scaling the overlink popup.

If supported, hide the overlay iframe within a shadow DOM to prevent tampering by (page) javascript.

Also handle AREA tags as links.

Suppress browser console error messages.

Bugfix: compensate for the height of the horizontal scrollbar when the add-on popup is displayed above the browser's native one. Replaces the defective version 3.6, which did not work for links inside (i)frames.

Fix problem with sites where page javascript appends stuff to the overlay iframe src attribute, causing severe breakage.

Fix (most cases of) the popup panel not always being visible immediately after page (re)load when the mouse is not moved.

Bugfix: do not show popup panel when all custom format strings are empty.

Only create overlay for HTML documents to prevent breakage of the tree view for XML documents.

This version is a rewrite of the extension as a WebExtension. As the WE API does not allow modifying the browser's native overlink popup, the default mode is to have a the link status popup above the native one with just the indicators and visit times.

This version adds some appearance customization options: the position of the overlink popup, wrapping the URL to multiple lines, and specifying custom colors or entire custom CSS.

Unfortunately (in addition to not being able to modify the native overlink popup) some functionality has been lost or degraded, see these issues. This is why this version is marked as requiring Firefox 57+: the legacy version is functionally better in the author's opinion, so an upgrade should not be forced on those with browsers still capable of using it. You can still force-install version 3.0 on an earlier Firefox if you want.
