Details

>>>   My Info:   Win7_64, Nightly 46, 32bit, ID 20151223030323
STR:
1. Set mouse option "when I rotate mouse wheel" in your OS to "scroll by 1 page"
2. Open http://maps9.navit-project.org/ in a new tab
3. Hover mouse over the map on the left side of the page
4. Rotate mouse wheel UP several times
5. Click "+" button in the map controls several times to increase zoom level "manually"
6. Rotate mouse wheel DOWN once

Result:       
 In Step 4 nothing happens.
 In Step 6 the map zoom level is set to minimum

Expectations: 
 In Step 4 zoom level sould increase by 1 "step" per rotation of mouse wheel
 In Step 6 zoom level sould decrease by 1 "step" per rotation of mouse wheel

Note:
 It works fine in IE11 and Chrome so this is firefox bug
