I'm using Firefox 32.0.3 and I need to learn how to change "window size". I have a + and a - in the tool bar but it only changes the window size in 10% increments. How do I get and intermediate increment changes......i.e. 15% or 18% or the like? Any help will be appreciated.

This is for the zoom buttons that enlarge and reduce the content size?

By default, the enlargement options are:

1.1 => 110%
1.2 => 120%
1.33 => 133%
1.5 => 150%
1.7 => 170%
2 => 200%
2.4 => 240%
3 => 300%

By default, the reduction steps are:

.9 => 90%
.8 => 80%
.67 => 67%
.5 => 50%
.3 => 30%

To add or modify these steps, you can edit this list in Firefox's about:config preferences editor. Here's how:

(1) In a new tab, type or paste about:config in the address bar and press Enter. Click the button promising to be careful.

(2) In the search box that appears above the list, type or paste zoom and pause while the list is filtered

(3) Double-click the toolkit.zoomManager.zoomValues preference and edit as desired. Since it's a little hard to read, you might want to copy it to a word processor or other program where you can zoom the text, edit it there, then copy back the revised version.

Note #1: After OK'ing this change, it will take effect in any new windows you open. Existing windows/tabs appear to remember the setting in effect at the time you opened them. (To move a tab to a new window, right-click the tab on the tab bar > Move to New Window.)

Note #2: if the preference becomes a mess, you can right-click > Reset it to restore the default.
