Using Mozilla.cfg to focus a custom new tab page

Hi everyone,

I am having trouble getting my custom new tab page to be focused when opened (instead of the address bar).

I am currently using the `autoconfig.js` + `mozilla.cfg` approach to overriding the `AboutNewTab.jsm` service with a custom local file. This is working great with the two files containing this code:

autoconfig.js: ``` pref("general.config.filename", "mozilla.cfg"); pref("general.config.obscure_value", 0); ```

mozilla.cfg: ``` // Custom firefox config

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

try {

 Cu.import("resource:///modules/AboutNewTab.jsm");
 let newTabURL = "file:///home/vallode/Documents/test/index.html";
 AboutNewTab.newTabURL = newTabURL;

} catch(e) { Cu.reportError(e); } ```

I have been attempting to use the `gBrowser` global to add an event listener to the new tab opening, but with no success. Could anyone point me in the right direction for something like this?

Chosen solution

I've had good success using the following defined in my mozilla.cfg

   // Auto focus new tab content
   try {
     Cu.import("resource://gre/modules/Services.jsm");
     Cu.import("resource:///modules/BrowserWindowTracker.jsm");
   
     Services.obs.addObserver((event) => {
       window = BrowserWindowTracker.getTopWindow();
       window.gBrowser.selectedBrowser.focus();
     }, "browser-open-newtab-start");
   } catch(e) { Cu.reportError(e); }
