Every so often we host community-driven curatorial projects to select new Firefox Recommended Extensions. By gathering a diverse group of community contributors who share a passion for the open web and add-ons, we aim to identify new Recommended Extensions that meet Mozilla’s “highest standards of security, functionality, and user experience.”

Earlier this year we concluded yet another successful curatorial project spanning six months. We evaluated dozens of worthy nominations. Those that received highest marks for functionality and user experience were then put through a technical review process to ensure they adhere to Add-on Policies and our industry-leading security standards. A few candidates are still working their way through the final stages of review, but most of the new batch of Recommended Extensions are now live on AMO (addons.mozilla.org) and we wanted to share the news, so without further ado here are some exciting new additions to the program…

Yomitan is a dictionary extension uniquely suited for learning new languages (20+). An interactive pop-up provides not only word definitions but audio pronunciation guidance as well, plus other great features tailored for understanding foreign languages.

Power Thesaurus is another elite language tool that provides a vast world of synonyms just a mouse click away (antonyms too!).

PhotoShow is a fabulous tool for any photophile. Just hover over images to instantly enlarge their appearance with an option to download in high-def. Works with 300+ top websites.

Simple Gesture for Android provides a suite of touch gestures like page scrolling, back and forth navigation, tab management, and more.

Immersive Translate is a feature-packed translation extension. Highlights include translations across mediums like web, PDF, eBooks, even video subtitles. Works great on both Firefox desktop and Android.

Time Tracker offers key insights into your web habits. Track the time you spend on websites — with an option to block specific sites if you find they’re stealing too much of your time.

Checker Plus for Gmail makes it easy to stay on top of your Gmail straight from Firefox’s toolbar. See email notifications, read, reply, delete, mark as read and more — without clicking away from wherever you are on the web.

YouTube Search Fixer de-clutters the YouTube experience by removing distracting features like Related Videos, For You, People Also Watched, Shorts — all that stuff intended to rabbit hole your attention. It’s completely customizable, so you’re free to tweak YouTube to taste.

Notefox lets you leave notes to yourself on any website (per page or domain wide). It’s a simple, ideal tool for deep researchers or anyone who needs to leave themselves helpful notes around the web.

Sink It for Reddit features a bunch of “quality of life improvements” as its developer puts it, including color coded comments, content muting, adaptive dark mode, and more.

Raindrop.io helps you save and organize anything you find on the web. This is a tremendous tool for clipping articles, videos, even PDFs — and categorizing them by topic.

Show Video Controls for Firefox is a beloved feature for watchers of WebM formatted videos. The extension automatically enables video controls (volume/mute, play/pause, full screen, etc.).

Chrome Mask is a clever little extension designed to “mask” Firefox as the Chrome browser to websites that otherwise try to block or don’t want to support Firefox.

Congratulations to all of the developers! You’ve built incredible features that will be appreciated by millions of Firefox users.

Finally, a huge thank you to the Firefox Recommended Extensions Advisory Board who contributed their time and talent helping curate all these new Recommended extensions. Shout outs to Amber Shumaker, C. Liam Brown, Cody Ortt, Danny Colin, gsakel, Lewis, Michael Soh, Paul, Rafi Meher, and Rusty (Rusty Zone on YouTube).

We’re planning another curatorial project sometime in 2026, so if you’re the developer of a Firefox extension you believe meets the criteria to become a Recommended extension, or you’re the user of an extension you feel deserves consideration for the program, please email us nominations at amo-featured [at] mozilla [dot] org.
