How do I set my local HTML page as a homepage?

Hi,

I like having my local HTML file as a homepage which gives me links to my favourite sites. However, Firefox doesn't seem to support loading a local homepage in a new tab. I have attempted to resolve this by setting up a server and using the My Homepage addon which kind of workds, but it's extremely slow and cumbersome.

Would be very grateful if someone had a better idea.

OK, I see what is wrong.

You need to add a third line to the autoconfig.js file.

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

Go to your settings and in there you can make whatever url your homepage.

Unfortunately, this exactly does not work with a local file. I want my homepage to be shown every time I open a new tab, but that doesn't work with a local address (file://address), only with a remote one (http://address).

You can use an autoconfig.cfg file to set the new tab page. This also works with a local page for me.


// first line is a comment
var {classes:Cc,interfaces:Ci,utils:Cu} = Components;
var newTabURL = "about:blank";
aboutNewTabService = Cc["@mozilla.org/browser/aboutnewtab-service;1"].getService(Ci.nsIAboutNewTabService);
aboutNewTabService.newTabURL = newTabURL;

You can use the autoconfig.cfg file in the Firefox program folder to initialize (set/lock) preferences.

The autoconfig.cfg file needs to be in the main Firefox program folder.

This requires a autoconfig.js file in the "defaults/pref" folder where the channel-prefs.js file is located that specifies to use autoconfig.cfg.

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

The autoconfig.cfg and autoconfig.js files need to start with a comment line (//).

Thanks for your reply, however, it doesn't seem to have worked. I added the two files into the relevant folders (/usr/lib/firefox/autoconfig.cfg and /usr/lib/firefox/defaults/pref/autoconfig.js, but sadly nothing has changed after restarting Firefox.

Sorry, I noticed that I made an error in the autoconfig.cfg file while pasting my own code.

Components["@mozilla.org/browser/aboutnewtab-service;1"] should be Components.classes["@mozilla.org/browser/aboutnewtab-service;1"]

I corrected the above posted code and tested it this time.

Thanks cor-el, but sadly this hasn't worked either. I get a blank page every time I open a new tab and have to manually click on the home button to get me to the homepage. I am still using the My Homepage addon, but there must be something which prevents it from accessing my local homepage.

I have also tried disabling the My Homepage addon, but that doesn't work at all as I end up on Firefox Home (the page with links to sites I recently visited).

Did you replace the about:blank value with the URL of your desired new tab page?

  • var newTabURL = "file:///...";

Yes, I did. It still doesn't change anything. I uploaded two screenshots to show you the current settings with the two created files and one to show what happens when I open a new tab.

You will have to disable the My Homepage extension that is controlling the new tab page as you can see in the third screenshot.

Are you sure that /usr/lib/firefox is the correct directory because Firefox would normally display a message at the top of the about:preferences page that an autoconfig file is active?

When I disable the addon a new tab shows the Firefox Home (the page with links to sites I recently visited).

I am not sure if it is in the right directory, however, I can show you a screenshot of my web console if it makes any sense to you.

Thank you, cor-el! That works great! You've made my day, I am ever so obliged! I'll think of you every time I open a new tab. ;-)
