How can I turn off the feature that, when I move my pointer over a headline, the headline pops up again as a seperate reader?

Question

Go to any website that has a link to a story. When I move the cursor over the link to the story a second version (read) also pops up. Why would somebody need to read the link twice in the exact same spot and why does it read over the original link I am trying to read?

-> Tap ALT key or press F10 to show the Menu Bar
-> go to Help Menu -> select "Restart with Add-ons Disabled"
Firefox will close then it will open up with just basic Firefox. Now do this:
-> Update ALL your Firefox Plug-ins https://www.mozilla.com/en-US/plugincheck/
-> go to View Menu -> '''Zoom''' -> click '''Reset''' -> '''Page Style''' -> select '''Basic Page Style'''
-> go to View Menu -> Toolbars -> unselect All Unwanted toolbars
-> go to Tools Menu -> Clear Recent History -> '''Time range to clear: select EVERYTHING''' -> click Details (small arrow) button -> place Checkmarks on '''Cookies, Cache''' -> click '''Clear Now'''
-> go to Tools Menu -> Options -> Content -> place Checkmarks on:
1) Block Pop-up windows 2) Load images automatically 3) Enable JavaScript
-> go to Tools Menu -> Options -> Security -> place Checkmarks on:
1) Warn me when sites try to install add-ons 2) Block reported attack sites 3) Block reported web forgeries
-> go to Tools Menu -> Options -> Advanced -> Network -> Offline Storage (Cache): click '''Clear Now''' button
-> Click OK on Options window
-> click the Favicon on SearchBar -> click '''Manage Search Engines''' -> select all Unwanted Search Engines and click '''Remove''' -> click OK
-> go to Tools Menu -> Add-ons -> Extensions section -> REMOVE All Unwanted/Suspicious Extensions (Add-ons) -> Restart Firefox
You can enable your Known & Trustworthy Add-ons later. Check and tell if its working.
