15 Best Mozilla Firefox Add-ons in 2023

Firefox add-ons are software or programs added into Mozilla Firefox to customize and enhance the browser’s functionality. Firefox add-ons are helpful for many purposes, including helping users execute tasks more efficiently and get more out of websites. Add-ons can add new features, alter existing ones, and improve users’ browsing experience by changing the browser’s appearance. Users can use add-ons to block adverts, download movies from websites, integrate Firefox with social media sites like Facebook and Twitter, and add extra features to increase the browser security.

Add-ons come in many different forms, available in both free and premium editions. Furthermore, some add-ons are produced with noble intentions, while developers design others to alter Firefox’s behavior in a harmful way. Adware programmers, for example, may install Firefox extensions without users’ consent to inject advertisements into websites and search result pages, take over the browser’s web page, insert in-browser miners, or attempt to steal login credentials from the websites the user visits.

Best Mozilla Firefox Addons

1. Hush

Hush is a Firefox extension that acts as a private bookmarking tool when used in incognito mode. Creating and accessing private bookmarks when surfing anonymously is only possible with Hush.

This add-on encrypts and secures password-protected bookmarks with an emphasis on security. Hush is only available in private browsing mode, and it allows users to organize multiple bookmarks with different passwords.

Hush has over 400 users and five reviews on the Firefox add-ons marketplace, averaging 3.4 out of 5 stars at the time of writing. Some of Hush’s critics cite difficulties in getting a quick response from customer service, particularly when it comes to changing customers’ sensitive information. Hush’s incompatibility with mobile browsers is another point of contention, as some users believe that this is when private bookmarks are most needed.


The Hush add-on was last updated on April 22, 2020, when version 2.0.3 was released. Although Hush is not as well-known as other add-ons, the software comes from a reputable developer who regularly keeps the code updated. Using encrypted bookmarks also adds a layer of protection to the user’s online experience.

The advantages of using the Hush add-on are listed below.

  • Users can save numerous bookmark sets using separate passwords.
  • Hush runs in private mode to avoid interfering with regular browsing sessions.
  • Enables the import and export of data.
  • Includes essential tools and settings for organizing links and bookmarks.

  • Hush users must regularly make manual backups of data.
  • Automatic data backup is not available.

Hush costs $1 per month or $9 per year for the premium version.

2. uBlock Origin

an image with uBlock Origin logo displayed on laptop

uBlock Origin is a free and open-source content-filtering and ad-blocking add-on that works seamlessly with Mozilla Firefox. The primary feature of uBlock Origin is CPU and memory efficiency. Although uBlock Origin is available for Chrome, Opera, Edge and other browsers, the Firefox version offers an extra function that helps counter websites’ attempts to bypass filters.

Using uBlock Origin, users can restrict JavaScript locally or globally by using the point-and-click feature. Users can also define customized global or local rules to override entries in filter lists and a variety of other advanced capabilities. Another valuable feature of uBlock Origin is the ability to block site trackers. This software protects users’ surfing data and eliminates the possibility that users’ every move will be tracked and used for targeted advertising.

The bulk of Adblock Plus’ filter syntax is supported by uBlock Origin. The popular filter lists EasyList and EasyPrivacy, and the malware website blocklist URLHaus is activated by default. The extensions can import hosts files, and community-maintained lists are available upon installation.

With more than 5.5 million users on the Firefox add-on store, uBlock Origin has garnered over 13,500 reviews and a rating of 4.8/5 stars at the time of writing. One of the most common criticisms about uBlock Origin is the lack of user instructions to help users navigate and comprehend the functioning of each icon. Some critics think the software does not prevent ads from YouTube, Twitter or other sites as users would expect.

uBlock Origin was first released on June 23, 2014, and by the winter of 2015, the software had expanded to other browsers. As of October 2021, the developer is still actively maintaining and updating uBlock Origin.

uBlock Origin is the best choice of add-ons because the software is swift, uses few system resources, and acts as an ad-blocker rather than allowing acceptable ads to load and display. The Firefox version even prevents IP leaks caused by WebRTC and anti-ad blocking measures. The more technical reason for this is that uBlock Origin supports scriptlet injection, allowing this add-on to cope with other unpleasant issues, such as sites that employ ad-reinsertion tactics.

  • uBlock Origin can be activated with a single click.
  • The software is light and compact.

  • The user interface only shows a limited amount of information.

The last update of Cookie AutoDelete was released on Jan. 20, 2021, with version 3.6.0. Despite criticism from some users, Cookies AutoDelete cleans away all data that hackers can use for tracking. Also, the flexibility to manage exceptions for each category per domain makes this add-on valuable.

5. Adblock Plus

an image with adblock plus mobile app on smartphone

One of the most popular free ad-blockers for Firefox is Adblock Plus. Adblock Plus is an open-source program that filters unwanted advertisements on Facebook, YouTube and other sites. By default, Adblock does not prevent unobtrusive advertisements but supports websites.

Users can effortlessly support preferred websites by whitelisting them, adding or creating custom filters, and restricting social media symbol tracking with additional features. Adblock Plus minimizes the time it takes for pages to load, lowers the danger of malware threats, and protects privacy by preventing trackers from spying on users’ online activities.

Adblock Plus has over 5.2 million users and has received more than 8,600 reviews averaging 4.5/5 stars at the time of writing. Adblock Plus’ critics argue that manually turning off ads is easier and faster than using Adblock Plus. Critics also feel that the developers are now being outsmarted by several websites that entirely bypass the program’s ad-blocking capabilities.

Adblock Plus was first launched in October 2005, and the most recent update, version 3.11.2, was issued on Sept. 1, 2021.

Because Adblock Plus is so effective at blocking ads, most users have donated to support the software.

  • Adblock Plus improves users’ online experience and addresses malware issues.
  • Adblock Plus protects users from being duped by deceptive advertising.

Ghostery is a web browser add-on that blocks advertisements, disables trackers and speeds up websites. Users may regulate who accesses their data by using Ghostery to view and block trackers on websites. To further protect users’ privacy, the enhanced anti-tracking feature anonymizes user data.

Users can adjust the display to only view important information with Ghostery’s numerous display and insight dashboards. Users may configure Ghostery to block trackers and secure personal data on a specific website with a single click.

Ghostery has over 1.1 million users with about 3,650 reviews averaging 4.3/5 stars on Firefox’s add-on marketplace at the time of writing. Because the software is supposed to be an ad-blocker, critics became frustrated due to unwelcome pop-ups, which fueled more criticism. Under the previous owner, Evidon, Ghostery had an opt-in feature called GhostRank. This feature filters ads and gives advertisers additional information, allowing them to better construct ads to avoid being blocked. One of the criticisms disclosed that the contract indicates that the commercial firm allegedly collects some users’ data and resells the data analysis or internet user behavior. Another criticism is that Ghostery is an advertising firm that allegedly competes against competitors to obtain a monopoly on the market.

Ghostery first launched in January 2010 and is now available for Mozilla Firefox, Google Chrome and other browsers since 2017. Version 8.5.7 was released on June 28, 2021, which was the most recent upgrade.

  • Users are protected from being tracked online.

How Firefox Addons Make Your Job Easier

an image with Mozilla Firefox open browser

Add-ons are features that are added to something to improve that thing. An add-on is a software expansion that enhances the program’s functionality. Users can use add-ons to add new features and functionalities to the program’s interface, improving the overall browsing experience. There are a variety of Firefox plugins that improve personal productivity by providing tools to help users work smarter and quicker. Some extensions help with writing, while others safeguard users’ eyes during day and night web surfing.

What Is the Importance of a Firefox Add-on?

Developers can use add-ons to enhance and change the functionality of Firefox. Standard web technologies like JavaScript, HTML, CSS and some dedicated JavaScript APIs create add-ons. An add-on can change the design of web pages, modify the Firefox interface and introduce new functionality to Firefox. Users can install extensions to hide ads, download movies from websites, integrate Firefox with social media sites like Facebook and Twitter, and add utilities not available in other browsers, such as translators.

How Do I Add Add-ons to Firefox?

The steps to add add-ons to Firefox are described below.

  • Press the application menu button in the top-right of the browser window.
  • Select the “Add-ons and themes” option from the menu.
  • Select an add-on to learn more. Tap the plus button to start the installation.
  • The interface will then display the extension’s access requirements.
  • To use the extension, tap “Add.”
  • Firefox will offer the option to use the software in private browsing after you install the extension. You can choose to enable “Allow in Private Browsing” now or later.
  • To finish, tap “Okay, Got It.”

Are Add-ons in Firefox Safe?

Yes, add-ons are safe in Firefox. Even though the Firefox store vets add-ons thoroughly for security purposes, this does not guarantee that all are completely secure. Users can choose between add-ons with the “recommended” label and popular add-ons for security reasons. Users should be cautious while installing add-ons, as this software may harm computers or breach privacy policies.

Can Installing Addons and Toolbars Slow Down Your Browser’s Performance?

an image with loading speed button on keyboard

Yes, installing add-ons and toolbars can slow down the browser’s performance because having more add-ons and toolbars means your CPU will have to work harder to handle everything at once.
