I am getting black and white "blocks covering my entire or parts of my whole browser when I am either loading a page, typing, or clicking a button while I am downloading a file. This happens every time.

Start Firefox in Troubleshoot Firefox issues using Safe Mode to check if one of the extensions or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance/Themes).

Try to disable hardware acceleration.

If disabling hardware acceleration works then check if there is an update available for your graphics display driver.
