Something changed in my Firefox display. It is now showing a large amount of space between text. Also, the fields for data entry have increased their size. Text size is okay. Thank you for your help.

Thank you Sriram for your reply. Unfortunately that didn't solve it. Does anything think it could be a problem with the settings in Windows? Although, Google Chrome and Internet Explorer are working properly.

Thank you cor-el. I worked through all your suggestions and unfortunately the problem was not resolved. It starts with the Firefox title bar being too big and wasting space. Then there are other anomalies in the way text is displayed. I'm wondering if something in Windows is causing this?

Start Firefox in Safe Mode to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem.

  • Switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance
  • Do NOT click the Reset button on the Safe Mode start window
