How to disable breadcrumbs in Eclipse
Solution 1
If you are referring to the breadcrumbs in the help file of a RCP application, there is only a manual way to do it.
Since Ganymede 3.4M5:

-
Michael Borgwardt mentions the toolbar icon
-
Slava Semushin provides a native shortcut based on Ctrl+3+
bread, which points directly to theToggle Java Editor Breadcrumboption. -
Shachi reminds us below that you can right-click on any icon on the breadcrumb, and select the entry named "
Hide Breadcrumb".

Original answer (manual way, through key mapping)
Find the file
org.eclipse.help.webapp\advanced\breadcrumbs.cssand replace its contents with.
.help_breadcrumbs {
display: none;
}
For the Java Editor breadcrumb, you need to assign a shortcut to the "Toggle Java Editor Breadcrumb" command (I have tested Alt+B, for instance)

That shortcut will make the breadcrumb bar appear/disappear at will.
Solution 2
With the editor window focussed, look for this icon in your toolbar: 
And click on it. That's all. The icon is present by default, but can be deactivated, in which case you have to activated as in MvanGeest's answer.
Solution 3
Another way which works for me at Eclipse Indigo (3.7): press Ctrl+3 and type bread, after that click on item Toggle Java Editor Breadcrumb.
Solution 4
- RightClick on any icon on breadcrumb.
- There is an option named HIDE BREADCRUMB.
- Click it and you are done. :D
Solution 5
Look for this icon in the toolbar:

This button toggles the Breadcrumb view on/off.
(I'm using Eclipse 3.7, and it's there by default)

NateS about 12 yearsFor some reason I didn't have the toolbar item, even though I had Java Editor Presentation checked. The key stroke worked. -

James McCracken almost 10 yearsJuno is version 4.2 (currently the newest) of Eclipse. -
earcam over 9 yearsHandily the accepted answer's length necessitates scrolling this one into view =) -
Pino over 9 yearsCreating a shortcut is not necessary. The best answer is the one by Michael Borgwardt but also the one by Slava Semushin is very interesting. -
Wes Winn over 8 yearsJust another thank you. Seriously, I've forgotten where the darn button is and wound up back here half a dozen times.
