Best Firefox Security Add-ons for Safer Browsing (2026)
In 2009 guest author Mary Ward recommended seven add-ons to secure Firefox, including Adblock Plus, NoScript, WOT and RoboForm. Some, like NoScript, are still going strong; others have been replaced by better tools or built-in Firefox features. Here are the best Firefox security add-ons for 2026, plus the settings that matter most.
Quick answer: For most people, install uBlock Origin (blocks ads, trackers and malicious domains), a password manager like Bitwarden, and Firefox Multi-Account Containers to isolate sites. Add Privacy Badger for extra tracker blocking and NoScript if you want strict script control. Then turn on HTTPS-Only Mode and Strict Enhanced Tracking Protection.

Best Firefox security add-ons
- uBlock Origin (external site): efficient blocker for ads, trackers and known malware domains.
- Privacy Badger: from the EFF, learns to block invisible trackers.
- NoScript: blocks scripts by default and lets you allow trusted sites; powerful but needs tweaking.
- Bitwarden: open source password manager with strong password generation and autofill.
- Firefox Multi-Account Containers: keeps banking, shopping and social sites in separate containers.
- Firefox Relay: email masks so your real address isn’t shared.
Old add-ons you no longer need
- BetterPrivacy, Stealther: discontinued; private windows and built-in cookie controls cover them.
- WOT: faced privacy criticism in 2016; rely on Firefox’s built-in phishing and malware protection instead.
- Toolbar password managers: use modern password manager extensions or Firefox’s own; see how to save passwords in Firefox.
Built-in Firefox security settings
- Settings > Privacy & Security > HTTPS-Only Mode in all windows.
- Enhanced Tracking Protection: Strict.
- Keep “Block dangerous and deceptive content” on.
- Turn on DNS over HTTPS for privacy on public networks.
- Keep Firefox updated automatically.
Install add-ons safely
Only install from addons.mozilla.org, prefer “Recommended” extensions, and check permissions. Too many add-ons can slow Firefox; see how to speed up Firefox.

ah,i like to used firefox web browsing
Hey do you have an updated list for this?
was searching for some add on’s for firefox security and now i have some real good options.thnx
thanks for sharing very usefull addons, i have installed them all to my firefox
Great list. Another add-on I would like to include is Billeo. It’s a free browser plug-in that manages passwords, saves receipts and auto fills forms. The tool is VeriSign secured and TRUSTe certified, so no security issues.
Thank you for the recommendation of WOT. We are pleased to be included with the other great add-ons.
This article is so timely because cybercrime is increasing with incidents of identity theft and rogue software costing users millions of dollars each month. The WOT community is working together to make the Web a safer place by discovering and rating websites which are safe to visit and those that are risky. I hope everyone who reads this article will use these add-ons to secure their systems.
Safe surfing,
Deborah
Great list.
I am the author of Ghostery https://www.ghostery.com/ which helps users block web bugs and protect their privacy. I hope it makes it to the next version of your list.
Cheers,
