How do I reset the zoom level in Firefox back to the default?
5 Answers
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. Commented Aug 9, 2013 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 ♦Commented Aug 9, 2013 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. Commented Aug 11, 2013 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!– AndreasCommented Sep 26, 2019 at 4:43
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.

Ctrl+0? I ask as a comment because I don't have FF handy to test. :)
