Using the latest code from the git repository and Firefox 51.0.1, visiting a protected site (e.g. fails and no login prompt is displayed.

I can confirm this. A currently still working workaround is using
Firefox ESR which is still available at version 45.8 But soon, Firefox
ESR will be bumped to be based on FF 52 or so and then that workaround
is gone.

This Mozilla bug seems to be related, although its fix might rather be
the cause than the fix as its said to have happened with Firefox
before 51:

The fix is in FoxyProxy's git repository at

The firefox diff that broke this for conkeror is here:

I believe the problem is that mozilla has replaced the getBrowser method with gBrowser throughout the
firefox code base. But conkeror only defines getBrowser in windows.js (line 200). 

Furthermore, there is a new getBrowserForContentWindow method that we need to define. See this seamonkey
bug for an example:

madalu: Thanks for these hints. Unfortunately they're not enough hints
for me to actually find a fix.

At least the following patch does _not_ suffice:

--- a/modules/window.js
+++ b/modules/window.js
@@ -198,6 +198,8 @@ function window_initialize (window) {
     // Add a getBrowser() and content to help certain extensions designed
     // for Firefox work with conkeror
     window.getBrowser = window_get_this_browser;
+    window.gBrowser = window_get_this_browser;
+    window.getBrowserForContentWindow = window_get_this_browser;
                             function () {
                                 return this.buffers.current.browser.contentWindow;

Sorry, I wasn't clear in my earlier post. The method getBrowserForContentWindow is invoked as follows in 

    let windows = Services.wm.getEnumerator(null);
    while (windows.hasMoreElements()) {
      let win = windows.getNext();
      let browser = win.gBrowser.getBrowserForContentWindow(aWindow);
      if (browser) {
        return { win, browser };
    return null;

So it is a method called on the browser object returned by gBrowser. And I believe it takes an instance of 
nsIDOMWindow as an argument. Its implementation in Seamonkey here (https://api- seems to suggest that it is called on an array of 
browser objects.

As I understand it, these methods were not exposed to any of the code conkeror relied on before; conkeror 
itself traditionally just hacked a getBrowser (i.e., gBrowser) method so that it could be called by 
extensions. But now these methods are directly invoked in nsLoginManagerPrompter.

Thanks to a patch sent to me (unfortunately only to me as it seems) by consolers(Madeleine@
on IRC in a /query, this bug is now fixed in git.

Will make an 1.0.4 release including that patch soon.
