I have Firefox 3.5.7 and after I installed a toolbar, whenever I open a new tab it opens with their website instead of a blank page. I uninstalled the toolbar and it still appears.

Where do I go to change that. From regedit?
Or some hidden place in Firefox?

  1. Type in about:config, in the location bar, that is the search field in your web browser you use to navigate to a website.

  2. Click OK on the warning message that appears.

  3. In the search bar on top search for, browser.newtab.url then right click on it and change it to what you want it to be, if you want a blank page, then just type in about:blank

I'd say, manual solution is prefereable instead of a commercial solution. – Markus Jul 10 '12 at 21:53

might not be that easy (yes, even Firefox can be 'hijacked' :).

run MBAM and scan for malware infections.

First, like Molly said, scan for rubbish.

After that, one of these two may help you:
New Tab Homepage 0.4.1 (then change the homepage to about:blank)
New Tab King 3.0.1

  1. Enter about:config into your location bar and hit Enter. [Ignore the fake warning if this is your first time there].
  2. Type in browser.startup.homepage in the filter box.
  3. Double click on the entry and put in about:blank if you want a blank page.

That is the browser startup homepage - not the page which is opening when you open a new tab. – Rook Jan 16 '10 at 2:06
@Idigas whoops looks like you are right. Too much browser hopping today for my neural circuits. – Adam Ryan Jan 16 '10 at 4:42

Click the middle button or ctrl-click on the home page icon. No add-on required.

I think the best solution to provide the ability you're looking for is a Firefox add-on called NewTabURL:


Select the default URL when new tabs are opened.

The options are: "A blank page", "The home page", "The current page" or a user defined URL.

When there is an URL in the clipboard, it is also possible to open automatically that URL in the new tab.

The two options Idigas mentioned behave a bit differently and may not have what you are looking for. New Tab Homepage loads your homepages(s) automatically in the new tab you open (which may not be the URL you want in the new tab). New Tab King opens up a menu of frequently used URL's, recently closed tabs, suggested sites. It has a lot of other doodads and configuration options such as sidebars, popup menus, etc. but I don't think you can just pick one URL for it to automatically load in a new tab.

This can be done easily. Just install the featured add-on My Homepage.

Go to ToolsAdd-ons. Simply disable all the add-ons. Then go to ToolsOptions and make sure that the URL for your home page is set to something you like, such as Google. Your new tabs will now open as a blank page.

Enter about:config into your location bar and hit Enter. When you receive the security message, just click on "I'll be careful, I promise"
Type in browser.newtab in the filter box.
Double click on the entry and put in the URL you want (for example

There is no browser.browser.newtab; perhaps you meant browser.newtab.url as answered by Max Jakobsson? – Bob Jul 1 '12 at 18:13
