Clicking on RSS link opens preview in new Firefox window.

I would like it to open in the same window as it did before in Firefox.

Never mind, I found this online solution: https://support.mozilla.org/en-US/questions/1226151

To make Firefox open all links in the same tab, follow these instructions: 
Type about:config in the Firefox address bar  
Bypass the security warning  
Find the browser.link.open_newwindow.restriction preference  
Double click it to change the value to 0  
Find the browser.link.open_newwindow preference  
Double click it to change the value to 1

Closing.
