What is a browser?
A browser is the software you use to visit websites.
What browser am I using?
There are a few ways to know which browser you are using, but one of the easiest might be to visit https://www.whatsmybrowser.org/ or https://www.whatismybrowser.com/.
What version is my browser?
The version of the browser you are using affects what the browser looks like, where you find settings, and sometimes what you can do in the browser. Browser updates help keep your browser secure (and sometimes introduce vulnerabilities, but it's more often a fix).
Checking the version you are running is slightly different depending on the browser you are using, but it is similar across at least the most popular browsers.
Open the menu (in Safari, the Safari menu; in Chrome, Edge and Firefox, the 3 dot or line menu) and look for the "About (this browser) menu option, which might be nested in the Help section of the menu (usually near the bottom).
Should I update my browser?
Yes, please.
