Customizing the download progress bar - Archive of obsolete content
in your overlay file, add a javascript file between the <overlay> and </overlay> tags: <script type="application/javascript" src="chrome://myextension/content/downloads-overlay.js" /> the javascript file will look something like this: var mydownloadmanager = { defaultcreatedownloaditem : null, init : function fdm_init() { mydownloadmanager.defaultcreatedownloaditem = window.createdownloaditem; window.createdownloaditem = function(aattrs) { var dl = mydownloadmanager.defaultcreatedownloaditem(aattrs); if (dl) { if (...whatever condition you use to decide whether to change this download...) { dl.setattribute("myspecialdow...
...nload", "true"); } } return dl; } } }; window.addeventlistener("load", function(e) { mydownloadmanager.init(); }, false); in your css file, change richdownloaditem (both occurrences) to richdownloaditem[myspecialdownload="true"].
