>>>   My Info:   Win7_64, Nightly 48, 32bit, ID 20160308030418
STR_A:
1. Open about:preferences#applications
2. Click string "Web Feed" on the page
2. Click menulist button next to the string "Web Feed".
3. Click "Use My Yahoo" to select it

STR_B:
1. Open about:preferences#applications
2. Replace favicon:
 2.1. Open devtools->Inspector
 2.2. Find element by selector   [type="application/vnd.mozilla.maybe.feed"]
 2.3. Find child element   .actionsMenu
 2.4. Find child element   xul:image
    [do not use element picker or you'll run into bug 1228675]
 2.5. Replace src to link location of attached "favicon 1"
3. Click string "Web Feed" on the page

AR:  Favicon is very huge
ER:  Favicon should be of normal size

Correction:
If you follow STR_B, you must click string "Web Feed" _before_ replacing favicon.
Also, the xul:image may not have [src] attribute at all. You must create it then. Also, I meant
"the 1st child element" instead of "child element":  menulist's dropmarker is also "xul:image"
