when i open a new site it always opens up on the side in a narrow window

I used to click on a site and it would always open up in the full screen. Now when I open a new site it always opens up in a narrow window on the left, 1/5th the size of the full screen, and continues to maintain the previous site in the remainder of the screen (4/5ths). The only way I can create the new site on the full screen is by dragging it over to the 4/5ths screen and then x'g out the narrow one on the left. Why is this happening and how do I eliminate it so that each time I open a new site it will open on the full screen?

Thank you in advance.

Are you using a bookmark? There is a little-known feature of bookmarks that can load them in Firefox's sidebar. This allows you to work with two pages side-by-side. To change that setting, right-click the bookmark > Properties, then uncheck the box for "Load this bookmark in the sidebar".

(You probably didn't set this yourself. If you use a link on a website to have the site add a bookmark to Firefox, due to restrictions on what sites can do, those will always be targeted toward the sidebar.)

If that's not it, have you noticed any pattern in when this happens?
