This is the most frustrating tech problem i’ve faced in a while. There are various solutions for various versions of Firefox, but none of them seem to work anymore because apparently Mozilla is waging a silent battle against people who want control over their own new tab page. For some reason.

Sorry. Just frustrated.

I’m making an HTML page that i would like LibreWolf to load by default every time i open a new blank tab with ctrl+t or the new tab button. I’m aware that i can set a new window page in my settings (not what i’m talking about), and i’m also aware of the browser extension that allows you to set a new tab page but is real buggy about local files. I’m even aware that i could hypothetically set my new tab page to a hidden page on my website that redirects to a local file, and i’m aware that that won’t work because links from HTTP(S) to File are disabled.

I have tried following the following guides and solutions.

As you might guess, none of them worked.

Here’s my current setup with this stuff.

I’m running GNU/Linux Debian 13 (trixie) with the KDE Plasma desktop environment version 6.3.6, KDE Frameworks version 6.13.0, and Qt version 6…8.2. But i doubt any of that matters.

LibreWolf was installed via apt and extrepo, and is on version 153.0.4-1.

I have a file at /usr/share/librewolf/defaults/pref/autoconfig.js:

// 
pref("general.config.filename", "autoconfig.cfg"); 
pref("general.config.obscure_value", 0); 
pref("general.config.sandbox_enabled", false); 

I have a file /usr/share/librewolf/autoconfig.cfg:

// sets the new tab page to out local newtab.
ChromeUtils.importESModule("resource:///modules/AboutNewTab.sys.mjs").AboutNewTab.newTabURL = "file:///home/indigo/Documents/browser-home/browserhome.html";

A copy of that same file is at /home/indigo/.config/librewolf/librewolf/librewolf.overrides.cfg

None of this seems to be doing anything at all. Maybe LibreWolf handles some of these file paths differently from Firefox, and that’s why no guides work. I don’t know.

Does anyone know a way to do this that works in version 153.0.4-1? Right now it seems like my best options are to stick with a blank page, switch to a Chromium-based browser like Vivaldi that actually lets me do this, or use New Tab Override to load this page from my website and potentially re-download a couple megabytes of images every time i open a tab. I don’t like any of those options.

So, again, does a solution currently exist, or has Mozilla won the war against customized home pages for new tabs? Does one of these still work and i just did it wrong? Will LibreWolf figure out that people want this and find a good way to implement it as a normal setting that doesn’t require a CS degree?
