I use to be able to change firefox icons by adding these files in Firefox under the browser directory

chrome/icons/default/BrowserPreferences.ico chrome/icons/default/CustomizeToolbarWindow.ico chrome/icons/default/default.ico chrome/icons/default/downloadManager.ico chrome/icons/default/main-window.ico chrome/icons/default/openLocation.ico chrome/icons/default/places.ico chrome/icons/default/printPageSetupDialog.ico chrome/icons/default/TabMIxPreferences.ico chrome/icons/default/unknownContentType.ico chrome/icons/default/viewSource.ico chrome/icons/default/Wizard.ico

It worked in version 56 but now in version 97 and this no longer works?

Hi,

at least main-window.ico should work, with a preference toolkit.legacyUserProfileCustomizations.windowIcon = true in about:config.
