Hi, there is no 'one size fits all' setting in Firefox. Instead, the zoom level you set on each site is remembered for next time - or until you change it.

Font size and zoom - increase the size of web pages

If your question is resolved by this or another answer, please take a minute to let us know. Thank you!

Not an answer. I don't want to zoom out on each new site... Sorry - it's called a computer, it's supposed to automate things...

Possibly your Operating System Windows 10 settings are not optimal. You probably should not need to Zoom out on all sites. Websites are generally deigned to display reasonably well on default or standard settings.

If you have particular needs you my wish to use some addon to make changes. Firefox is highly customisable.
