PDF.js has a button with a bookmark icon and the tooltip “Current view (copy or open in new window)”. The button is actually an ordinary HTML link to the current document including an anchor for the position and zoom level (compare with links on maps). One could probably divine that from the icon, but the tooltip is confusing, because ordinary links have the same set of context menu items, but they don’t have any special hints about them. People who would want to open the current view in a new window may want to do that for other links too, and there may be little reason for this link to be different. Possible solutions: 1. Change the tooltip to “Current view link” or “Link to the current view”. 2. Have something like “(right-click for the options)” in the tooltip. This one does not help to denote linkness by itself, so still misleading. 3. Implement “Current view” for all pages or even files viewed in Firefox. ;-)

I'm not sure the icon is very clear either. Maybe similar icons are used in different applications for the same feature, but I couldn't figure out what it was supposed to represent.

In the Russian version, the tooltip says: “[a/the] link to the current view (copy or open in a new window)”
