Firefox Extensions for Long-Term Investors: Watchlist Without a Brokerage Dashboard

Long-term investors — people who hold positions for months or years — have different browser needs than active traders. The goal is not tick-by-tick monitoring but periodic portfolio awareness: a morning check, a check after major news events, an end-of-day summary.

Here is a Firefox setup for long-term investors.


The core tool: Stock Market Dashboard

Stock Market and Finance Dashboard — your holdings and watchlist on the new tab.

For a long-term portfolio, a typical setup might include:

  • The positions you hold (3-10 symbols)
  • Key index benchmarks (S&P 500, total market, international)
  • 1-2 economic indicators (10-year Treasury yield, USD index)

Each new tab shows current price and day change. No login, no account linking. The check takes 5 seconds.


News from your sources

News Widget Dashboard — RSS headlines from financial and economic sources.

Useful RSS feeds for long-term investors:

  • Federal Reserve announcements (federalreserve.gov has RSS)
  • BLS employment data releases
  • Companies you hold (many have investor relations RSS feeds)
  • Financial news publications

This surfaces relevant news without requiring you to visit news sites with their engagement-driven interfaces.


Habit tracking for investment discipline

Habit Tracker — track investment-related habits monthly.

Long-term investing habits to track:

  • "Reviewed portfolio" (1×/month)
  • "Read annual report for position X"
  • "Rebalanced if needed"
  • "Did not panic-sell" (a simple emotional discipline tracker)

Quick calculations

Quick Calculator — percentage and arithmetic calculations on the new tab.

Common investment calculations: "what percentage of my portfolio is this position?", "what return do I need to break even?", "what is 4% of this amount?" The new tab calculator handles these instantly.
