The bad news is that modern EWMH X programs generally don't supply their icons as files in the filesystem; instead, they provide multiple sizes of icons as X properties, which you can usually see by using 'xprop' on a suitable window (it's all of the _NET_WM_ICON stuff, and I think the WM_HINTS stuff, although I don't know how the bitmap ids are used). If you want to see what size of icon fvwm is using for some window, you can use 'xwininfo' on the icon; this will tell you the icon's Width and Height. The actual source PNGs for these Firefox icons are present in the source code but are magically bundled into the compiled and installed Firefox. Never the less you can simply pull the PNGs out of the source code, once you know the magical location. Probably the simplest way is through the Github Firefox mirror, where I believe you can find all of the sizes in the default*.pngs here: https://github.com/mozilla/gecko-dev/tree/master/browser/branding/official So, basically, you probably want to use xwininfo on an Opera icon to find out how big it is, then download the appropriate sized defaultNN.png file and set it as Firefox's icon. This will override anything Firefox is hinting to fvwm and fvwm is picking up on. - cks
