Explore Firefox’s new semantic search feature and help shape it

Firefox Development

Hi Mozillians :waving_hand:

Firefox is introducing Semantic History Search, a new feature that makes it easier to search your Firefox history by understanding the meaning and context, instead of relying solely on keywords. Built on a vector-based model, it offers a more intuitive browsing experience while keeping your data private by processing everything locally on your device.

With the release of Firefox Beta 142, Mozilla’s community will be among the first to experience this new feature and provide feedback directly to the team behind it by participating in this campaign. Your input will help shape the feature while it’s still in development.

This event is organized by Mozilla Support in collaboration with Firefox QA. Mozilla Support is a global community of enthusiastic volunteers and staff working together to help users through the community forums, help articles, and article localization.

Hi folks,

Good news! You’ve got extra time to join the Test Days. :tada:

Due to a recently discovered regression (tech happens :sweat_smile:), we’re extending the campaign through August 1, 2025.

The team is currently looking at Monday or Tuesday next week to push the fix. Just make sure to update your Firefox Beta before diving in!

Thanks for your patience and happy testing! :rocket:
