After using an HDMI cable to connect to a large TV, my tabs, buttons and icons are so large they no longer fit on my screen

Tell me how to reduce the size of buttons, tabs, and everything else BUT the fonts in my browsers. All of them have been affected. I've exhausted all of the normal "look in Settings and use your brain" options.

I assume you already tried exiting Firefox and starting it up again.

Firefox 103 beta has a new feature to react to your system-level text enlargement setting. You can roll that back as follows and see whether this helps at all:

(1) In a new tab, type or paste about:config in the address bar and press Enter/Return. Click the button accepting the risk.

More info on about:config: Configuration Editor for Firefox. The moderators would like us to remind you that changes made through this back door aren't fully supported and aren't guaranteed to continue working in the future. Since we have had this setting for a long time and I use it myself, I feel comfortable mentioning it.

(2) In the search box in the page, type or paste browser.display.os-zoom-behavior and pause while the list is filtered

(3) Double-click the preference to display an editing field, and change the value to 0 then press Enter or click the blue check mark button to save the change. For reference, this preference can have 3 values:

  • 0 => Ignore the OS-level scaling (per tester on Reddit, might make UI text smaller than version 102)
  • 1 => Apply OS-level scaling as proportional zoom [default]
  • 2 => Apply OS-level scaling as text-only zoom

Setting 2 was the Golden Ticket. Fonts are legible, buttons and icons are all back to Human scale. Thank you so much!
