Is it possible (by Addon or something else) to change the viewport size of a webpage in Firefox for every visit (by domain/url)? Problem: Some pages don't have readable layouts thus I want to set the width of them to a readable size. Comparable to the developer tools (F12) where I can simulate different viewport size for development purposes - but I need this in daily browsing routine.
