Browsers -are the programs that allow you to interface with the internet.  The most common are Safari, Firefox and Chrome. Avoid Microsoft Edge as part on your ongoing goal of harm reduction. It’s just another product that Microsoft is phoning in to try and keep you normalized to their cynical business plan.  I recommend installing a couple (there are more to try). It just takes a few minutes. The reason to do this is because as web developers build new websites they also have to make sure that the content shows up and works correctly on all the major browsers.  Sometimes they don't succeed. I prefer Chrome or Firefox. Do some research. Do not try to uninstall Microsoft Edge. That is FORBIDDEN by your computer and meant to create problems if you try. Don’t be afraid to jump ship if any browser you are using becomes annoying.
