How do I make the top of the FF page text larger? I can make what shows below larger but not what is at the top of the page.

And this goes to any page I open, even MS office programs. Even with my reading glasses I can't read the very small text. - jb

Can you attach a screenshot?

You can look at this thread:

  • /questions/1384204 Since the last update, the Firefox screen does not fit my system setting(125%)

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. On the warning page, you can click "Accept the Risk and Continue" to open about:config.
