What’s new or coming up in Firefox desktop

There are a number of new features launched recently or upcoming in Nightly to look out for.

Smart Tab Grouping

With the recent release of Tab Groups in Firefox 137, we’ll see some additional development on enhancements in the future. Currently only available in English on Nightly, Smart Tab Grouping uses a local AI model to suggest similar tabs to group together.

Link Previews

This feature will be coming to Firefox Labs in 138, Link Previews uses a local AI model to quickly see what’s behind a link, by distilling key points from the page.

Signing in PDFs

You have likely seen these strings while working on Beta, but the ability to add signatures using the built-in PDF editor will be released fully in the upcoming 138 release on April 29.

What’s new or coming up in mobile

We’re adding customization options for Firefox icons on mobile! Some of the icon names may be tricky to localize, so we’ll be sharing a reference sheet that includes each icon along with its visual and contextual usage. This will help you choose the most accurate and user-friendly translations for your locale. Keep an eye out for upcoming Pontoon notifications for more details!

What’s new or coming up in web projects

AMO and AMO Frontend

To enhance user experience, the AMO team has established a minimum translation completion threshold of 80% for locales to remain on production sites. The team will start implementing the new policy in May. Last month, locales with a completion rate of 40% or lower were removed from the production site. However, affected communities can continue making progress in Pontoon, and their status will change once they meet the threshold.

Once this new standard is fully implemented, the addon team will reassess the list of locales on a monthly basis, evaluating those that have met or fallen below the 80% threshold. Based on this review, they will determine which locales to retain and which to remove from the production site. Regardless of your locale’s current status, you can check your work in context using the links to the production, staging, and developer sites which can be found on the top left of the project dashboards.

What’s new or coming up in Pontoon

We’re working on some sizable back-end improvements to how Pontoon internally represents and deals with translatable messages, i.e. source-locale entries and their translations. Thus far we’ve refactored Pontoon’s sync code (how it reads from and writes data to project repositories) and the serialization of our supported file formats; the next step will be replacing our file format parsers.

Mostly this work should remain invisible to users, though it has already allowed us to fix quite a few long-standing bugs and improved sync performance. Eventually, this will make it much easier for us to expand the file formats and features supported by Pontoon.

Events

We are hosting our first localization office hour on Apr 30, 2025 at 3:30pm UTC, it will be live streamed on both AirMozilla and YouTube (recordings can be found at the same links). This session will focus on common errors localizers may encounter and how to overcome them. Feel free to ask questions beforehand via the Google form or reach out directly to delphine at mozilla dot com.
