Select View » Zoom » Reset from the menu.

Alternatively press Cmd + 0 on Mac OS X, or Ctrl + 0 on Windows and Linux.

  • The menu no longer exists in Firefox, but the keyboard shortcut still works. – Burhan Ali Aug 09 '13 at 22:06
  • @BurhanAli Still exists on Firefox 23 on OS X and Firefox 20 on Windows. What version and OS are you referring to? – Daniel Beck Aug 09 '13 at 23:04
  • My mistake. It seems the standard menu bar is hidden now until you hit Alt. I don't use Firefox regularly enough these days so to me it looked like the menu bar was no longer there at all. – Burhan Ali Aug 11 '13 at 19:49

Go to View > Zoom > reset
alternatively you can press ctrl+0

Go to "View" in the menu, then "Zoom" and then "Normal". Or just press 'Ctrl + 0' (Zero)

To reset the zoom level on all pages go to about:config and set browser.zoom.siteSpecific to false.

  • Probably the only practicable solution on Firefox mobile since it has no View menu and no CTRL key! – Andreas Sep 26 '19 at 04:43

This fixed it for me

about:config on layout.css.devPixelsPerPx to modify its value. The default is -1.0 in Firefox 22 and above. Change it to 1.0 to make it work like in previous Firefox versions.
