UX Playground
Firefox S&S prototypes
Prototypes
Block AI overviews on SERP
An official path to remove AI overviews from search results pages, to deter users from using custom search engine settings (which loses Mozilla search-partner revenue from that user forever)
Default SE → unavailable
How we message a user when their default search engine becomes unavailable and Firefox switches them to another — shown as a notification banner over a web page.
Suggestions sizing
The address bar and its suggestions panel, as the starting point for a set of prototypes about how the suggestions are sized.
Edit search shortcuts
Inline chip-based editing for each search engine's shortcuts.
HNT search
Making it clearer you can start a search directly from the New Tab screen, so people know they don't need to navigate to a search engine first.
HNT search widget
A New Tab widget that resurfaces your searches to help you pick a search task back up.
Google Lens
When Google is selected as a search engine, a Lens icon appears at the right-hand end of the search box. Click it, or drop an image into the search box, to search with Google Lens. You can also right-click any image on the page and choose “Search image with Google Lens”, which needs the extension installed.
Search sidebar
Opens beside your search results with easy-access search suggestions and deep research tools. Prototype limitation: it can’t auto-open, you need to click the icon in the sidebar (or press ⌥D).
Complex Search
Opens the Firefox sidebar with a shared chat box at the bottom — anything you type is saved with your email and the time, so it becomes a running chat for everyone with the extension.
Highlight to search
A toolbar of actions alongside any text selection. Search, copy, translate, or ask AI.
Server not found
Prevents server not found errors from being dead ends. Compare the split-view, prominent-search and auto-run variants.
Suggestion explanations
“Last visited” and “Bookmarked” explanations on Firefox address-bar suggestions, exploring how they sit alongside each row's title and URL as the suggestions panel changes width.
Load missing favicons
When you sync bookmarks from another device, Firefox doesn’t load their site icons for privacy reasons — leaving blank favicons right when a new user is most likely to churn. This adds a way to load the missing ones.
Treasure hunt
A three-question treasure hunt that starts in a New Tab widget and runs in the sidebar. Each answer is out there on the web — you have to search your way to it, and the clock is running.
Support Firefox
Add a search engine that Firefox already works with, and you can choose to let those searches fund Firefox. You get the same results, and nothing extra is tracked.
Promote Nova themes
A feature callout for people who do not like Firefox’s new look: a way back to the old colours, and a way on to the rest of the themes.
