These are very old news (I’m sure), but I’ve just stumbled upon two useful keyboard shortcuts for Firefox.
- ⌘ + L — jump to and select (ready for overtyping) the contents of the location box.
- ⌘ + K — jump to and select (ready for overtyping) the contents of the search box.
In other words, you don’t need to reach for the mouse when typing a new URL or searching for something. I’m sure everyone’s been using these for ages, but they’re a revelation to me…
Update: Thanks to Mark for pointing out that ⌘ + L also works in Safari — but ⌘ + K doesn’t…
