Every morning I open three tabs: email, the market overview, and my project tracker. The market overview is a habit, not an obsession — I want a 20-second glance at whether the day is green or red before I context-switch into focused work.
Loading a full finance site for a 20-second glance felt wasteful. Ads, popups, a heavy page. I built a lighter version into the new tab instead.
Stock Market Dashboard for Firefox: the basics
Shows live stock quotes and financial news on every new tab. Add tickers you care about. The dashboard shows:
- Current price
- Daily change (absolute and percentage)
- Color-coded up/down indicator
- Financial news headlines
The quotes are market-delayed for most symbols. For a morning glance at whether the market is up or down, delayed quotes are fine. For intraday trading, you need a proper trading platform.
Why I did not add alerts
Alerts would require a background service. A background service either runs in Firefox (draining battery) or runs on a server (introducing cloud dependency and ongoing cost). Neither is appropriate for a lightweight new tab extension.
If you need price alerts, your brokerage has them. This is a glance dashboard, not a notification system.
The news component
Financial news is part of the market context. The dashboard shows current headlines alongside the price data. These are from public RSS feeds — the same approach as News Widget Dashboard. No proprietary data feed.
Portfolio tracking: what this is and is not
You can add multiple tickers and see their daily performance at a glance. This is not portfolio tracking in the sense that it does not know how many shares you hold, your cost basis, or your P&L.
For actual portfolio tracking: your brokerage's app. For a glanceable "what are the markets doing" overview: this extension.
