All text is partly garbled and makes it hard to read. When doing a screenshot next to Chrome it doesn't show, so had to take a picture of the screen, but I can only upload low resolution picture, so the difference is not that clear. The hardware setup is brand new Dell Precision 5560 running Windows 11 Pro version 21H2, with new Dell 27" monitor.

Taking a Screenshot; I always use: Windows > Start > search box > Snip. Select Snipping Tool. Use a compressed image type like PNG or JPG to save the screenshot.

Let's start with, [v56+] Type about:preferences#general<enter> in the address box. Under fonts and colors, press the Advanced button. Scroll to the bottom, turn on Allow Web Sites To Choose Their Own.

Make sure you haven't enabled a High Contrast theme in the OS settings.

  • We have seen reports that this can be caused by a problem with fonts like Roboto or Helvetica that

you have installed locally and that might be corrupted or are missing some variants. Also, make sure you allow pages to choose their own fonts and that you do not block remote (downloadable) fonts.

  • If you use uBlock Origin make sure not to "block remote fonts".

You can try to disable hardware acceleration in Firefox.

Close and restart Firefox after modifying the setting to make changes effective.

You can check if there is an update for your graphics display driver and check for hardware acceleration related issues.

When taking a screenshot by using the snipping tool, then there is no difference between Chrome browser and Firefox. The text for Firefox is only partially garbled.
