Add-ons (also known as extensions) are small programs that run inside web browsers like
Mozilla Firefox. They add extra features to the browser without having to download anything
new. You can use extensions to make browsing faster, easier, and safer. Some extensions even
let you do things like translate text on websites, search the web, and play games.
There are over 28,000 Firefox-addons and 480,000 themes, making it hard to find the best
ones. so we have created a way to sort through all of them. Use the dropdown above to set
different filters. Add-ons are sorted by number of active users.
To set even more advanced filters, and sort the Firefox add-ons differently,
please visit our Advanced search tool. Note that Advanced
search tool is only available to premium members.
