5 Firefox New Tab Extensions Compared: Which One Actually Improves Your Workflow?

Your browser opens dozens of times per day. Each time, you see the new tab page for a split second — maybe less. That's hundreds of micro-moments that currently show you... nothing useful.

Here's a comparison of the top Firefox new tab extensions, from a developer who builds them.

What Makes a New Tab Extension Good?

Before comparing, let's define the criteria:

1. 
   Information density — does it show me something useful?


2. 
   Load time — does it slow down new tab opens?


3. 
   Privacy — does it track me?


4. 
   Customization — can I make it mine?


5. 
   Free tier — is the useful version free?

The Contenders

1. Momentum Dash

Verdict: Beautiful but limited (free tier)

Momentum shows a beautiful photo, the time, and a daily focus prompt. Premium unlocks weather, todos, and more widgets. The free tier is minimal — just time and a pretty background.

• Load time: Fast


• Privacy: Account required (tracks usage)


• Free tier: Very limited


• Customization: Moderate (premium)

2. New Tab Override

Verdict: Developer-focused, total control

New Tab Override lets you set any URL as your new tab page. It's pure configuration — no widgets, no weather, just "open this URL when I press Ctrl+T."

• Load time: Depends on the target URL


• Privacy: Excellent (no data collection)


• Free tier: Full feature (open source)


• Customization: Unlimited (you control the URL)

3. Tabliss

Verdict: Most customizable

Tabliss is a widget-based new tab with backgrounds, weather, clock, to-do lists, and more. Each widget is modular and configurable.

• Load time: Moderate (many active widgets can slow it)


• Privacy: Good (self-contained)


• Free tier: Full feature


• Customization: Excellent

4. iTab New Tab

Verdict: Feature-rich but heavy

iTab packs in a lot: bookmarks, apps, wallpapers, weather, search. It's essentially a mini dashboard.

• Load time: Slower (many features)


• Privacy: Mixed (some features call external servers)


• Free tier: Full feature


• Customization: High

5. Weather & Clock Dashboard

Verdict: Focused on the essentials

This is the extension I built (.

If you want complete flexibility, New Tab Override combined with a locally-hosted page is unbeatable. If you want maximum widgets, Tabliss has the most.

The one I'd avoid: any extension with a required account on the free tier. Your new tab page shouldn't phone home every time you open a tab.

I build Weather & Clock Dashboard. All benchmarks were performed on my own machine; YMMV.
