You can manually make the window narrower of course, but it doesn't play nice with tabbed browsing. In particular, you now face a choice: 1. Make the current window narrow. But when I switch to other tabs in this window, I need to expand it again, because the people who wrote them assumed there would be many horizontal pixels available. (Responsive layout? What's that?) 2. Move this tab into it's own window. But what to do if I then follow further links that point to other sites? If I open them in the same tab, I must resize again. If in a new tab: should this tab be manually migrated to my wide window? Or should I resize the narrow one? The ideal solution would be a browser feature (like Reader Mode or Reading View).
