New Firefox causes display errors on websites

After upgrading Firefox I have a variety of display errors with websites, some worse than others. IE and Chrome do not have these problems. I have tried refreshing Firefox and I have twice deleted it and re-downloaded the program with no improvement. Sometimes the errors disappear after moving the cursor over the problem. I cannot find anything on the Forum which fixes the problem. I am attaching some screen shots to illustrate the problem.

You can try to disable hardware acceleration in Firefox.

  • Tools > Options > Advanced > General > Browsing: "Use hardware acceleration when available"

You need to close and restart Firefox after toggling this setting.

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