Customize New Tab with a local HTML file after Firefox 136
Hello,
I wanted to customize my Firefox new tab with a local HTML file, such as "/path/to/my/index.html". It was possible to use this workaround: https://github.com/Jangsoodlor/Firefox-New-Tab-Config/tree/main https://github.com/Jangsoodlor/Firefox-New-Tab-Config/tree/main
Which implied a configuration file (sometimes named "autoconfig.cfg", "firefox.cfg", "local-settings.cfg" depending on the guide since the name is arbitrary) with javascript code. In the new Firefox 136, this code fails to execute due to a new API being used.
If you want to customize your new tab, follow the previous guide, but on the configuration file write this code instead:
// My new tab
try {
const ff = {};
ChromeUtils.defineESModuleGetters(ff, {AboutNewTab: "resource:///modules/AboutNewTab.sys.mjs"});
ff.AboutNewTab.newTabURL = 'file:///path/to/my/index.html';
} catch (e) {ChromeUtils.reportError(e);}
Note that the file must start with a comment
Adapting the "/path/to/my/index.html" to your needs.
Thanks to @mkaply (github) on this thread https://github.com/mozilla/policy-templates/discussions/1190 for the new API method.
I post this here in case someone has the same issue, because is quite recent and hard to find on the internet.

An internal file name changed, so you need to update that in your startup script.
AboutNewTab.jsm => AboutNewTab.sys.mjs

Oh wait, you are trying to post a solution, but your code is a mess. Please use <pre> before and </pre> after your code block so the syntax isn't mistaken for markup.

You should post that to github where your getting customization from and ask of the users there whom would know more on the changes and how it works as well. And being recent that would be the most likely place to post as that is where the creators would be to see and check how it works.

Thank you so much jscher2000!
I wish I had seen the support question you linked before, it would have saved me all the trouble.
Also, I have added the < pre > tags as you suggested ^.^
