Embedded Files
A picture is worth one-thousand words, and when users aren’t willing to read one-thousand words online, it’s to your benefit to provide great product imagery. Visuals can help people learn about and remember your extension, making installation decisions easier. Extension images are also featured prominently on your product page.
In a 2018 addons.mozilla.org survey of 7,000+ users, about one-third considered the extension’s screenshots when making a decision whether or not to install.

Do This
Do This
- Include a how-it-works image. Research shows that users can be confused about how to use an extension once they have installed it, and may uninstall as a result. Include images that show your extension in action, with key features highlighted.
For example, if your extension blocks ads, show what the user will see when an extension blocks an ad, including any scorecards that track number of ads blocked. - Include 4-6 images
- Include promotional images that highlight any awards, editorial features, or impressive user stats.
- Use annotation to point out features. If you plan to localize your extension, localize those captions.
- Make the images large. There’s no maximum, and the larger your images, the better the resolution. We recommend 2400 x 1800 pixels.
- Select a primary image and order your screenshots to tell a story. This will help users better understand how your extension works and its value.
- Include context. Users shouldn’t wonder, “What am I looking at here?”
Not this
Not this
- Don't include other browsers’ user interface in your screenshots. AMO serves Firefox users, so show your extension living in Firefox!
- Don't repeat the same screenshot in different languages.
