Extensions or add-ons are software programs, typically developed by a third party, that allows you to add features to Firefox to customize your browsing experience.
There are more than 20,000 extensions listed on addons.mozilla.org (AMO), Mozilla’s official directory for Firefox add-ons. Most extensions are created by trustworthy developers. However, bad actors may put your security and privacy at risk by using extensions to compromise your data.
To protect your safety and privacy, you can use these tips to assess the safety of an extension before installation, or install extensions that are regularly reviewed by Mozilla staff. You’ll know if an extension is being regularly reviewed if it has one of the badges listed below on addons.mozilla.org (AMO) and the Add-ons Manager in Firefox.
Recommended extensions are editorially curated extensions that meet the highest standards of security, functionality, and user experience. Firefox staff, along with community participation, selects each extension and manually reviews them for security and policy compliance before they receive Recommended status. These extensions may also qualify for promotions on the AMO homepage and other prominent locations. Developers cannot pay to have their extensions included in this program.
