Switching from Chrome to Firefox: What Happens to Your New Tab Extensions?

If you're considering switching browsers but don't want to lose your current workflow, the question isn't just "which browser is better" — it's "what will I lose and gain specifically?"

Here's the honest comparison for people who currently use a new tab extension on Chrome and are considering Firefox.

What You Keep

Your browsing habits: Firefox can import Chrome bookmarks, passwords, and history. Your existing workflow transfers.

Most extensions: The majority of popular Chrome extensions have Firefox equivalents. Check AMO (addons.mozilla.org) before switching — Firefox equivalents for uBlock Origin, Bitwarden, LastPass, Grammarly, and most major extensions are available.

Your Google services: Gmail, Google Docs, Drive, Meet all work in Firefox. A few edge cases have minor friction (some enterprise Google Workspace features); most consumer Google services work identically.

Your muscle memory: Keyboard shortcuts are nearly identical. Ctrl+T, Ctrl+W, Ctrl+Shift+T all work the same way.

What Changes for New Tab Extensions

The Chrome Web Store isn't available: Chrome extensions install from the Chrome Web Store; Firefox extensions install from AMO. Most popular Chrome new tab extensions have Firefox equivalents, but not all.

Setting expectations for the new tab:

  • Chrome's default new tab: Google Search + frequently visited sites + Google Lens
  • Firefox's default new tab: Firefox Home (Pocket recommendations + top sites)

If you're using a custom Chrome new tab extension, look for its Firefox equivalent on AMO before switching.

The Weather New Tab Specifically

If you use a weather new tab extension on Chrome and switch to Firefox:

Weather & Clock Dashboard on Firefox provides:

  • Live weather + 3-day forecast
  • World clocks (useful if Chrome extension had this)
  • No account requirement (unlike many Chrome weather extensions)
  • MIT open source

The Firefox version of a weather new tab extension is often better from a privacy perspective because Firefox's extension ecosystem has fewer extensions with aggressive data collection models.

What You Gain

uBlock Origin at full capability: On Chrome, Manifest V3 has weakened ad blocking. On Firefox, uBlock Origin maintains full blocking capability.

Total Cookie Protection: Firefox's default third-party cookie isolation is more thorough than Chrome's.

Multi-Account Containers: No Chrome equivalent. If you manage multiple accounts, this is a significant gain.

No dependency on Google for the browser itself: Firefox is developed by Mozilla, not Google. Your browser isn't a Google product collecting data about your browsing for advertising.

What You Lose

Chrome DevTools as the canonical dev experience: If you're a developer targeting Chrome (which is the majority of the web), Chrome DevTools is the primary debugging environment. Firefox DevTools is good but different.

Better Google Meet/Workspace integration on Chrome: Some Google products work marginally better on Chrome — though for most users this isn't perceptible.

Chrome Web Store extension selection: The Chrome Web Store has more extensions. Most important ones are on AMO, but niche developer tools sometimes aren't.

The Transition Approach

For a risk-free transition:

  1. Install Firefox alongside Chrome (don't uninstall Chrome)
  2. Import bookmarks and passwords
  3. Find Firefox equivalents for your extensions
  4. Use Firefox as primary for 2 weeks
  5. Decide whether to make it permanent

Most people who try this find Firefox perfectly capable. The minority who switch back usually do so for a specific developer tool or enterprise workflow that works better on Chrome.
