Changes to the localization team

A lot has changed in the team this year. Delphine and Peiying left Mozilla a few months ago, and we’re now happy to welcome three new members:

Camila (parker) will focus on our mobile projects (Android and iOS), while also helping with Spanish localization.
Eda (edie) will focus on our web projects (mozilla.org, firefox.com, AMO, etc.), while also helping with Turkish localization.
Eric (ewerybody) will work alongside Eemeli and Matjaž to support and improve our localization infrastructure, including the moz-l10n library that powers several features in Pontoon.

For both Camila and Eda, contributing directly in Pontoon will also be an important part of getting to know our localization community. By working as localizers themselves, they’ll experience firsthand the challenges contributors encounter and gain a better understanding of how our communities organize and work together.

In the coming months, we’ll publish a series of blog posts to introduce our new team members — and reintroduce some familiar faces, since it’s either been a while or we never got around to introducing them when they joined.

What’s new or coming up in Firefox desktop

Firefox 155 Beta

Today marks the beginning of the Beta cycle for Firefox 155 and the start of the shift to Firefox’s 2-week release cycle. You can find more information on this change and how it affects you in our update here: Firefox Release Changes and Localization.

Themes

A new part of the upcoming Firefox redesign is a number of built-in themes a user can select for their profile. The theme-picker.ftl strings are landing in Firefox 155 and include a number of theme names which are short, evocative names in English. We have generated a reference document to help with creating localized names in your languages, it includes both testing instructions and screenshots.

What’s new or coming up in SUMO

We would love more helping hands to bring the following locales across the finish line:

Spanish – 48% remaining
Japanese – 19% remaining
Portuguese (Brazil) – 11% remaining
Portuguese (Portugal) – 17% remaining

If you’re a contributor in one of these locales, now is a great time to jump in. Every translated string brings us one step closer to shipping a better experience for users around the world!

What’s new or coming up in Pontoon

Editor theme. The translation editor can now follow your theme choice. You can set the editor theme independently of the main interface — Light, Dark, or Main to match the rest of Pontoon. The change comes from Ayush (ayshushus), who is interning with the L10n team and wrote about the work on this blog back in July.

Copy from another locale. A new batch action lets you copy translations from another locale into the strings you’ve selected. It’s especially handy for closely related languages, or for locales that share terminology and want to bootstrap from an existing translation as a starting point. The feature was contributed by Serah (MundiaNderi), a volunteer contributor who wrote about her work on Pontoon earlier this year.

Copy from another locale

Community health. Teams can now follow their Community Health Score over time in a new chart on the team Insights tab, alongside the existing activity charts. The L10n team also gets a cross‑locale overview to spot communities that may need support. The dashboard was built by Jamie (functionzz), who is interning with the L10n team. See his previous blog post on translation search unification.

Composed Machinery suggestions. Fluent messages with attributes or selectors used to require copying each field separately, one match at a time. Machinery now offers a single suggestion that covers the entire message: every field is filled from a perfect translation memory match, falling back to machine translation, and one click copies all of them into the editor at once.

Composed Machinery suggestions

Automatic LLM suggestions. Until now, getting an LLM suggestion meant opening the AI menu on a machine translation result and picking an option. The suggestion is now generated automatically and shown as its own entry in the Machinery panel. We’re starting with a limited rollout — signed‑in users, strings without an approved translation, and a small set of locales — so we can evaluate quality and cost before expanding. The AI menu keeps working as before, in every locale.

Other improvements. A number of more focused changes also landed, thanks to our contributors:

Notifications about new strings now link only to the strings that were actually added, instead of the full resource — by flodolo (#4185).
A year selector was added to the chart on profile pages — by flodolo (#4205).
The list of translations on a Search page is now more compact and easier to scan — by functionzz (#4157).
Search boxes now look and behave consistently across the entire app — by MundiaNderi (#4301).
A clear “String not found” page is now shown when the active filters don’t match the string you’re opening — by ayshushus (#4281).
Profile images from Mozilla accounts are now supported — by wassafshahzad (#4215).
String counts in the translate interface are now formatted using your locale’s own conventions instead of a hardcoded en‑GB — by ewerybody (#4127).

New contributors. We’re happy to welcome another group of contributors who made their first patches to Pontoon in the past few months: Kasturijadhav14 (6 patches), eshu3104 (2), jbuck, troypsierrallc-dot, msranjana, and denyshon. Their work spans notifications, contributor profiles, documentation, UI polish, the API, and infrastructure — thank you all!
