Top Mozilla Firefox Add-Ons You Should Use

With 800+ million users worldwide and 250+ million active users per month, Mozilla Firefox is one of the most popular web browsers in the market. Firefox is fast, allowing users to leverage multiple cores in ways that competitors can’t. Firefox also comes with a cleaner, more modern user interface and better privacy protections. And that’s not all. The Firefox browser features a strong add-on community that allows users to customize their web browsing experience. 

Firefox add-ons and extensions let you change Firefox appearance, customize the user interface, add functionality, add more features to your web pages, and block ads. Here are the top Firefox add-ons everyone should be using. 

Mozilla Firefox Add-Ons You Should Use

Dark Reader

Dark mode is one of the best things to have on your apps. It makes bright colors easy to read, resulting in less eye strain. Nearly all social media apps have a dark mode. While Firefox has several dark options, it doesn’t always work on most websites. Dark Reader is an open source browser extension that creates dark themes for websites on the fly. This extension even allows you to choose which websites to apply a dark theme to and which ones should be left the way they are. 


Lightshot is one of the handiest tools on Firefox. This browser extension allows you to take screenshots of web pages displayed on your browser. You can customize the screenshots in whichever way you like using Lightshot. This extension also allows you to search for similar images on the web. You can use Lightshot to highlight anything on the web page and add texts and shapes as much as you like. Once you take a screenshot, you can choose to save it, print it, or share it via social media. 

uBlock Origin

Online ads can be both annoying and distracting. uBlock Origin is an all-round content filtering tool that you can use to enhance your web browsing experience. 

You can use this free, open source browser extension to block all types of annoying online ads, including pop-up ads, banner ads, YouTube video ads, and websites that track your online activity. 

uBlock Origin is less resource-intensive compared to other ad blockers — it uses less memory with more or less the same features. You can customize filters on uBlock Origin all you like. 


Privacy can be an elusive thing on the internet. There are trackers, hackers, and other online threat actors watching everything that you do online. The most effective way to protect your privacy on the internet is to download a VPN. ExpressVPN is one of the best Mozilla Firefox extensions when it comes to securing your internet connection. It encrypts your internet traffic, spoofs your location, and lets you access the internet from anywhere. The Firefox add-on for ExpressVPN will link to the more secure HTTPS URLs automatically.

Undo Close Tab

Have you ever closed a tab on your browser by accident? It’s annoying. It’s even more exasperating when you are racing against deadlines and don’t have time to scour through your browser history looking for that particular page. Fortunately, Undo Close Tab helps you ensure that you never have to go through that. This nifty Firefox add-on allows you to open a recently closed tab with one click. You can choose from a list of 25 recently closed tabs for more convenience. 

Cookie AutoDelete

Browser cookies are meant to make websites easier to use, but they also track your online activity and populate your tabs with targeted ads. They are not only creepy, but they also bog down your browser. Cookie AutoDelete is a Firefox add-on that automatically removes cookies from the tabs that you close. This extension can also delete cookies from a specific domain. Cookie AutoDelete ensures that your browser doesn’t remember your information or track your browsing habits, enhancing your privacy on Firefox.

Image Search Options

Google’s reverse image search is one of the most useful hacks on the internet. It allows you to search for different versions of any image you stumble upon on the internet. You can further simplify the reverse image search feature by installing the Image Search Options extension on your Firefox browser. This tool makes effortless reverse image searches possible and, in addition to Google, comes with various search engines. Simply right-click on any image you come across to pull up a context menu with 11 image search engines. 


Grammarly flags typos and helps you make your documents, messages, and social media posts clear and impactful. It makes your communication better. If you make many mistakes as you type, adding Grammarly to your browser will make your life significantly easier. The good news is that Grammarly is available as a free Firefox add-on, but a paid version is also available. In addition to spelling mistakes, Grammarly highlights grammatical errors and even offers suggestions to improve your writing. 

Multi-Account Containers

We do almost everything online these days, including working, shopping, socializing, banking, etc. If you are only using a single browser, it’s easy to get different aspects of your online life mixed up. Multi-Account Containers is a Firefox add-on that allows you to keep different parts of your online life separate. This extension lets you carve out a separate, color-coded tab for each of your online lives. Each tab stores cookies separately, so you don’t have to worry about online trackers. 


Bitwarden is a completely free and open-source password manager tool. This application makes it easy to generate and store unique passwords for any browser or device and is available as a Firefox add-on. Bitwarden protects your passwords with advanced end-to-end encryption, ensuring that everything is private and secure. Bitwarden is compatible across platforms and is packed with premium features.
