Can you please tell me how to make the top and sidebar text in Firefox as large as that in the website window?  Thank you.

The font/text sizes in the main window are fine and easily adjustable. But the text in Bookmarks and the top parts of Firefox pages (address bar, tabs, quick links row) is so small it's difficult to read. I've searched for a way to enlarge it, but can't find one. I've been trying to adjust the text size on my new PC, but it seems when I get it right on the desktop screen, it's either too small or too large on something else. If it makes a difference, I'm using Windows 11 on a Dell 8960 desktop PC. Can you please tell me how to make the top and sidebar text in Firefox as large as that in the website window? Thank you.
