Change new tab page to local file

[shdowmyst]

Previously I was able to use custom local file as a new tab page using this code in firefox.cfg:

var {classes:Cc,interfaces:Ci,utils:Cu} = Components;

try {
  Cu.import("resource:///modules/AboutNewTab.jsm");
  var newTabURL = "file:///D:/Documents/images/home.html";
  AboutNewTab.newTabURL = newTabURL;
} catch(e){Cu.reportError(e);} // report errors in the Browser Console

Which no longer works in firefox 136 sadly, Is the a policy, or updated code for firefox.cfg that can fix that?

We moved away from JSMs.

Try:

ChromeUtils.defineESModuleGetters(this, {
AboutNewTab: "resource:///modules/AboutNewTab.sys.mjs",
});

No promises though.

Anything in autoconfig that relies on Firefox internals can break.

That helped, thank you!
Any way for a more permanent solution? The issue is local html files loads a random background from about 2gb of images, and packing that into an addon is too big.

We don't have any plans to make the new tab page configurable in that way.
