First, FB came out blurred with broken typefaces. Then I could comment on posts. It looks like my computer is forcing me to use Explorer Edge.

You may have zoomed web page(s) by accident. Reset the page zoom on pages that cause problems.

  • View > Zoom > Reset (Ctrl/Command+0 (zero))

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

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

Can you attach a screenshot?

  • Use a compressed image type like PNG or JPG to save the screenshot
