Without Mouse how to use Firefox

Navigation from the toolbar

1. Select location bar: Ctrl/Cmd+L or Alt+D
2. Select search bar: Ctrl/Cmd+K
3. Back: Backspace or Alt/Cmd+Left
4. Forward: Alt/Option+Right or Shift+Backspace
5. Change search engine: Ctrl/Cmd+Down (Next) +Up (Previous)

Opening pages

Unless you do all of your browsing in one page, these shortcuts are huge when you don't want to go running for your mouse.

1. Open link in new window: Shift+Enter
2. Open link in new tab: Ctrl/Cmd+Enter
3. Open address/search in new tab: Alt/Option+Enter

Used together with their respective shortcuts (address and search bar shortcuts and the find-as-you-type link shortcut), the page opening shortcuts go a long way toward mouse-less browsing.
