Adjust Firefox page size and print a reading copy on Mac
Command-Plus and Command-Minus change Firefox page zoom on Mac; Command-0 resets it. Command-P opens printing. Page zoom and print layout are separate views, so inspect both when preparing a readable copy.

- Firefox · Firefox for macOS; Mozilla documentation checked 4 November 2026. Defaults, not a runtime version certification.
- Keyboard and customization
- English documentation and US-style key names. Punctuation and function keys can differ on other layouts.. These are documentation-backed defaults, not a hands-on test. App settings, operating-system shortcuts, extensions and keyboard layout can change what happens. Check focus and the current app menu or shortcut settings when a binding differs.
- Review basis
- Documentation reviewed 2026-11-05 by Codex — source and editorial review; no runtime test. These bindings were not tested in a running app for this guide.

Use page zoom for one difficult page
A browser page can need a different reading size from the rest of the desktop. Increase it in small steps and check how the website rearranges navigation and text. If every application is difficult to see, inspect system display or accessibility settings separately instead of assuming page zoom controls the entire Mac.
Inspect printing as its own layout
A comfortable screen view does not guarantee a useful printed copy. Open the print dialog and inspect the page range and visible content before choosing an output destination. Some websites provide a different print stylesheet, so sidebars, headings or interactive content may be handled differently from the live page.
Recover and compare before committing
If a site looks unexpectedly enlarged, reset zoom first and then choose a deliberate size. On another keyboard layout, use the shortcut shown in Firefox’s current menu if the plus character is awkward. Practice on a public article: enlarge it, reset it and compare its print preview without sending anything to a printer.
