The Firefox screen seems too big. For example, when I use Messenger on the Facebook page, the typing box at the bottom is too low to be seen or used. I have tried the CTRL- option. That makes the font smaller, but the bottom is still missing.

You can look at this thread:

If setting browser.display.os-zoom-behavior = 0 doesn't work for you then you can create a new Number pref on the about:config page and set its value to 100.

Paste ui.textScaleFactor in the search bar and select the Number radio button and click the '+' button to add the new Number pref, enter the value (100) and click the blue OK button to confirm.

  • about:config => ui.textScaleFactor = 100

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.
