20 Best Firefox Extensions That Are Safe, Verified and Useful

Hello friends, Firefox is one of the most popular and privacy-friendly browsers in the world after Google Chrome. There are thousands of options in its add-on or extension store to make Firefox's performance even better. However, not all extensions are safe.

In today's post, I will share with you 20 such Firefox extensions that are verified by Mozilla (Recommended Badge), completely safe and will make your daily browsing much easier. For your convenience, they have been arranged in several categories:

1. uBlock Origin

This is not just an ad-blocker, it is an efficient content blocker. It consumes very little RAM or processor of the computer and increases page loading speed by blocking all annoying ads and trackers.

2. Firefox Multi-Account Containers

Firefox's own official extension. With this, you can log in to multiple accounts of the same website (such as two different Facebook or Gmail) in separate containers or tabs in the same browser, and the data from one will not enter the other.

3. Bitwarden

A very secure, open-source and free password manager. All your website passwords will be saved here in an encrypted state, which will protect your accounts from hacking.

4. Privacy Badger

This extension, created by the non-profit organization EFF, automatically identifies invisible trackers in the background and blocks them from stealing your data.

5. Cookie AutoDelete

Whenever you close a browser tab, this extension will immediately delete all the cookies left by that website. As a result, no one will be able to track you.

6. ClearURLs

When we copy a link from the Internet, many tracking codes (such as ?utm_source=...) are added to the end. This extension cuts out that dirty or tracking part from the link and creates a completely fresh and small link.

Productivity and Daily Work

7. Dark Reader

It converts the white background of websites that do not have their own night mode or dark theme into a dark mode that is comfortable for the eyes. This is a must-have for night browsing.

8. TWP – Translate Web Pages

This is the best open-source extension to translate the entire webpage into your own language (such as Bengali) with one click, like Google Chrome.

9. LanguageTool

This is an excellent privacy-friendly writing assistant. It corrects grammar and spelling mistakes in real-time while writing mail or posts in English.

10. SingleFile

If you want to save a useful webpage or article for offline reading, it converts the entire page (including images and styles) into a single HTML file and saves it.

11. Tab Session Manager

This is a lifesaver for you if you have a habit of keeping multiple tabs open in your browser. It saves the sessions of all your open tabs, so that even if the browser crashes, all the tabs can be restored with one click.

12. Absolute Enable Right Click & Copy

Many websites block right-clicking or selecting text to copy. By enabling this extension, you can easily copy information from those sites.

Media and Entertainment

13. SponsorBlock for YouTube

It automatically skips the annoying sponsored parts, intros, or subscription requests while watching YouTube videos through crowdsourcing.

14. Enhancer for YouTube

This is an all-in-one tool for YouTube lovers. With it, you can control the volume of the video with the mouse scroll, turn on the cinema mode, and keep the video quality fixed in advance.

15. Return YouTube Dislike

After YouTube officially hides the dislike count of a video, this extension brings back the original number of likes and dislikes of the video on the screen. As a result, it is easy to understand whether the video is useful or useless.

Advanced and Technical Tools

16. Wappalyzer

This is especially useful for developers and technology lovers. By opening any website and clicking on this extension, you can see which programming language, CMS (such as WordPress) or framework the site has been built with.

17. Violentmonkey

This is an open-source user-script manager. Through it, you can change the functionality of any website by running custom JavaScript code.

18. Buster: Captcha Solver for Humans

It automatically solves the annoying image CAPTCHAs that come when you enter various sites on the Internet through audio recognition.

19. LocalCDN / Decentraleyes

When a website loads, it loads various files from your computer's local library instead of downloading them from a third-party CDN. This reduces tracking and makes pages load super fast.

20. User-Agent Switcher and Manager

With this tool, you can fake your Firefox browser's identity as any other browser (e.g. Chrome, Safari) or operating system (e.g. Android, iPhone). This is quite useful for opening many sites that only open on phones on a PC.

A Little Tip

Extensions that have a green trophy or 'Recommended' badge next to them in the Firefox Extension Store are code-reviewed by the Mozilla team to ensure their security. So it would be wise to always check this badge when using an extension.
