How do I change the zoom increment that is used by Firefox whenever I zoom-in or zoom-out of webpages?
I find that the default zoom increment is a bit too big for my taste.

You can do this as follows (I tried it with Firefox 10.0.2 here):
about:config
in the address bartoolkit.zoomManager.zoomValues
This will show you the various zoom "steps" the browser has. The steps are specified as decimal numbers (representing precentages of the original, so .3 means 30% of original), separated by a ,
. See Tweak Firefox 3 full page zoom for the details.
1This works, but *Firefox must be restarted* before it takes effect (at least in the most recent version of Firefox, 34). For instance, opening a new tab is not enough. – Peter Mortensen – 2014-12-07T19:24:45.917
Restarting Firefox required: similar to Super User question How to permanently zoom in Firefox without using addons?.

I don't have enough points to comment on Bhargav Bhat answer, but it seems that the
toolkit.zoomManager.zoomValues
as not effect when you use <kbd>CTRL</kbd> + <kbd>Mousewheel</kbd>. But it is taken into account when you zoom: - Using <kbd>CTRL</kbd> + <kbd>-</kbd> or <kbd>CTRL</kbd> + <kbd>+</kbd>
