User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:45.0) Gecko/20100101 Firefox/45.0 Build ID: 20161130223840 Steps to reproduce: Visited a webpage in Firefox. Might only happen with a fresh install/upgrade of Firefox. Actual results: Reader View message pops down from the address bar. I find it ironic/funny that the Reader View pop-up says: "Remove clutter so you can focus exactly on what you want to read." Expected results: I'm trying to view the webpage and navigate the menus of the webpage but this pop-up message is in the way blocking my view and not allowing be to use all menuitems of the website.

This popup was removed in Firefox 55 in bug 1352501.
