The developer theme

A theme focused on developers

Features & Capabilities

The Developer Theme — a new tab built for people who live in the terminal.

Turn every new tab into a productivity dashboard instead of a blank page. Track your day with a built-in to-do list, watch your GitHub contribution heatmap glow green, catch the weather at a glance, and jump straight to your favorite sites with one-click shortcuts — YouTube, Gmail, GitHub, Claude, ChatGPT, Gemini, and anything else you add.

Feeling curious? A fresh "Question of the Tab" keeps your brain warm between builds.

Make it yours: switch accent colors, resize fonts, upload your own wallpaper or let a curated rotation surface a new one every tab — smoothly blurred in, never a jarring flash. Every setting lives entirely in your browser; nothing is ever sent anywhere.

Highlights:

📋 Quick-add to-do list 🐙 Live GitHub activity heatmap ☁ Weather, auto-located or set manually 🧠 Bite-sized trivia questions 🔗 Customizable shortcut bar with auto-fetched icons 🎨 Custom accent color, font size, and wallpaper blur 🖼 Seamless, flash-free wallpaper transitions 🔒 100% local — no data collection, ever

Is The developer theme Safe?

Risk impact
Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

The developer theme requires some sensitive permissions that could impact your browser and data security. Exercise caution before installing.

Risk impact analysis details
  • Critical Allows access to all websites, posing a significant security risk as it can monitor and modify data from any visited site.
  • Critical ******* ****** ** *** ********* ******** **********
  • Medium *** ***** *** *** ********* ****** ****** *** **** **** ********** ** ****** **** ***********
Risk likelihood
Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.

The developer theme is recently added, and hasn't been around long enough for us to gather enough data to accurately assess its risk level.

Risk likelihood analysis details
  • High This extension was recently updated in the past month. New updates may not be stable or safe.
  • High **** ********* *** *** **** ****** ********* ********** *** *** ** ****** ** *****
  • Medium **** ********* *** ***** ** *** **** * ******* *** ********** *** *** ** ****** ** *****
  • Good **** ********* *** **** **** *******
