As a web designer and developer, my eyes are incredibly important to me and I hate to strain them. If you’re constantly working on the computer in a dimly lit room like me, you definitely want to consider using night mode in developer tools, and you should also be wearing some blue light eliminating glasses while running a scheduled night shift on your display. For generic night mode browsing and reading, I’ve been using the Dark Night Mode Firefox add-on as it works tremendously well. Here’s how to switch to night mode in developer tools in Firefox.

Switch to night mode in Firefox developer tools in just a few steps:

  1. firefox how to enable night mode developer tools step 1First, you need to open your developer tools by pressing “F12” on your keyboard, or you can right click anywhere inside the browser viewport and then click on “inspect element.” I prefer the F12 keyboard shortcut, but here’s another secret tip for directly accessing a specific element in developer tools: right click on whatever element you wish to inspect and then press “Q” on your keyboard to quickly open developer tools for that element.
