If you place the cursor on the location bar and press tab, it moves into the content of the www page. If you then press shift-tab to move back to the location bar, it doesn't work. You actually have to press shift-tab 3 times.
Confirmed on linux 7/22 branch It really does not bug me The first shift-tab is to go to the start of page I dont know what the second one is for... And the third does what you expect Keyboard navigation
here you go
