Nice extension especially for websites that don't have reader view automatically available. Best part is, this extension doesn't require any permission. It works fine when we want to open a link of open the current page in a new reader view tab.

There is one minor issue though. "Switch to Reader View" context menu which I think will open the current page in reader view in the current tab does not work. Nothing happens when clicking on this menu item. But for the same page, "Open in Reader View" works which opens the page in reader view in new tab.
