I don't think so.

var {classes:Cc,interfaces:Ci,utils:Cu} = Components;
var wm = Cc["@mozilla.org/appshell/window-mediator;1"].getService(Ci.nsIWindowMediator);
var gB = wm.getMostRecentWindow("navigator:browser").gBrowser;

var l = gB.mPanelContainer.childNodes.length,i;
for(var i=0;i<l;i++){
cD=gB.getBrowserAtIndex(i).contentDocument;

/* more code */
}

Cycling through tabs is not to difficult to do via the Browser Console. You can store the screenshot on the clipboard and save the image file yourself. The most difficult would be to know when one screenshot has finished so you know to proceed to the next tab. *https://dxr.mozilla.org/mozilla-release/source/devtools/shared/gcli/commands/screenshot.js ---- <pre><nowiki>var {classes:Cc,interfaces:Ci,utils:Cu} = Components; var wm = Cc["@mozilla.org/appshell/window-mediator;1"].getService(Ci.nsIWindowMediator); var gB = wm.getMostRecentWindow("navigator:browser").gBrowser; var l = gB.mPanelContainer.childNodes.length,i; for(var i=0;i<l;i++){ cD=gB.getBrowserAtIndex(i).contentDocument; /* more code */ }</nowiki></pre>
