What do you mean all browsers? There are so many browsers in the market. Here I would list the steps to change default homepage of Chrome, IE and Firefox for you.
Change home page in Internet Explorer:
Open Internet Explorer, select the Tools button , and then select Internet options. On the General tab, under Home page, enter the URL of the site you want to set as a home page. You can add more than one URL, or add the site you're currently viewing by selecting Use current. If you add more than one URL, put each URL on its own line. Select Apply, and then select OK. The next time you open a new browsing session or window (or select the Home button ), your home pages will be loaded automatically.
Change home page in Firefox:
1. Click the Menu button, select Options and then choose the General panel.
2. Find the Home Page section and change your homepage address.
3. Close the browser.
Change home page in Chrome:
On your computer, open Chrome. At the top right, click More. Select Settings. Under "Appearance," check the box Show Home button. Below "Show Home button," click Change to choose your homepage. Click on OK.
