The Font size seems to be reducing to such a degree, that I can barely see it now. Is there an easy way to increase the Font size on the very top tool bar in blue background, just like I used to do using Theme Font & Size Changer?

You can set layout.css.devPixelsPerPx to 1.0 (default is -1) on the about:config page.
Adjust its value in 0.1 or 0.05 steps (1.1 or 0.9) until icons or text looks right.
Modifying layout.css.devPixelsPerPx affects user interface and web pages (global zoom).

You can open the about:config page via the location/address bar. You can accept the warning and click "I accept the risk!" to continue.

Firefox 73+ comes with a Zoom section in Options/Preferences to set the default zoom setting for web pages.
