How do you open the Eclipse web browser?

Right click a file in left Project Navigator, and in the pop up context menu, chse Open with ..., and then you can find it in sub menu.

Actually, I don't like to use it.

You can add the button and menu option to launch the Internal Web Browser to any perspective. Right click on the toolbar and select "Customize Perspective...". Then click the Command Groups Availability tab and check the Web Browser command group in the list on the left to make it available.

The Web and Java EE perspective will reveal a button on the toolbar to open a new web browser.

Also, from Window > Show View you find the Internal Web browser view.

The former acts as an editor tab, the later not.

For Eclipse 4.6.3,

select Window > Preferences > (in the left pane)select )"General" tab and 'Web Browser'
