Mozilla is more than any group or product. It's the Rebel Alliance A community working to make tech serve everyone, not just the shareholders of seven companies. Technology should be more than a vehicle for profit. It should empower people to live more fulfilling lives. That's Mozilla's mission.

Lots of new faces around here lately 👋 So let's refresh: What actually is Thundermail? Privacy-first email from the makers of Thunderbird. No ads, tracking, or AI training on your email. Full breakdown 👉 sohub.io/oub2 Join the waitlist: sohub.io/opq0 #thundermail #opensource #email

Let’s complete former Mayor Sly James’ campaign to get our children reading better. | Opinion

Thunderbird Appointment will always be open source. Repo here: github.com/thunderbird/... Come to talk us. We'll help you move off Cal.com

Get off Gmail, use Thunderbird (and soon Thundermail). www.androidpolice.com/giving-up-on...

Can we learn something about how to use tech in a healthy way from... The Amish? I think we can. ryanleesipes.me/what-the-ami...

“Our mission has always been to prove that you can imagine and innovate without exploitation. Mozilla Foundation is honored to be part of this Council that embodies those principles at exactly the scale and moment it’s needed most.” Perfect words for what we need to do @nabiha.bsky.social

Tech Cooperative? Been thinking about how the Thunderbird (Community) Council being involved in our business helps us avoid enshittification. How could we turn that system into something that is more inclusive of all users? Been fascinated by how Coops (think REI) democratize the corporation.

We are building tech you can trust. Thank you to @ostifofficial.bsky.social and 7A Security for their collaboration on the security audit for Thunderbird Send, our end-to-end encrypted file transfer service (coming to everyone soon, open source now). blog.thunderbird.net/2025/12/thun...

Truly open, real choice and trustworthy. Mozilla's take on AI. Listen to @mozilla.org President Mark Surman talk with the Financial Times about our vision for AI. youtu.be/eBjqeLg1csI?...

"Big tech. The mainstream of tech is wired to harvest our creativity, to harvest our data, to harvest our money. Only to benefit a few people. We can and must build a different kind of tech industry, that has humans in mind and shares the wealth with all of us"

The internet should belong to all of us 👏 This Giving Tuesday, stand with the people building a tech future that’s open by design and shaped by community. Your contribution today sets the bar for what good technology can be. Join us 💙 mzl.la/48O36Rd

"Your scientists were so preoccupied with whether they could, they didn't stop to think if they should." Strangely seems appropriate for both Jurassic Park and Silicon Valley.

Due to my job making email application @thunderbird.net, I'm contractually obligated to watch You've Got Mail each year. Amazing how relevant the movie still is. Great afternoon with a brew from @boulevardbeer.bsky.social called "The Nutcracker", Tom Hanks and Meg Ryan. Here we go. 💌 :)

The AI debate is stuck between doom‑sayers and hype‑machines—what we need are Realists who see generative AI as the powerful, imperfect tool that it is. Join me in being a Realist. ryanleesipes.me/i-hope-the-a...

A look into how we (Mozilla) think about our role to play in the AI landscape. We're trying to build a future where people are empowered by AI, not drowning in slop.

You've got to actively make the world you want to live in.

This city really shines in fall. Lots of people planted trees, whose shade they never sat under here in KC. Quite literally.

Exactly. Lots of people find speaking to a computer naturally and getting an understandable response is useful to many. Denying that lots of people are using AI makes it *very* hard to have a real discussion about solutions to the problems these big AI platforms are creating.

When did we forget that we had power? That the only way to change things was to DO SOMETHING to change it. Let's imagine a hopeful future - and then go out and make it happen.

Exchange/Microsoft365 account support built into Thunderbird now! Thunderbird users have asked us for this for years and now it is here. Enjoy. For nerds: the architecture built for this opens the door for JMAP support. blog.thunderbird.net/2025/11/thun...

This post from @anildash.com perfectly encapsulates the disconnect in the discussion of AI. Plenty of real people get value from interacting with LLMs. We can't afford to cede this technology to Profit-at-all-costs Big Tech.

They grow up so fast 😁

There's definitely nothing shady in these algorithms... 🤣

Europe can lead the way on using open source. By supporting open source software, these projects become a better public good for all. That's the type of thing all governments should be doing.

Look right there... It's @thunderbird.net !

On November 9, 2004, Mozilla Corporation released a multiplatform web browser, Firefox 1.0. Firefox gained major popularity among users and exceeded 1 billion downloads between 2004 and 2009. #WebDesignHistory

At Mozilla we make tech that puts people before profit. We make tech that is designed to help people live better lives. We make tech that is GOOD.

If you use products and services from companies that actively undermine what you value - can you truly claim to value those things? It's a hard question, but we live in a time where choices abound. Choose to live your principles. #privacy #democracy #tech ryanleesipes.me/convenience-...

"Perhaps our task is to imagine other ways of being human - that reflect our deep-seated interdependence as people and planet."

Do something good for someone today. 👍

Our users aren't the product, they are our partners.

Remember way back when the Web felt hopeful, and we all thought tech would bring us together in a beautiful deeply connected future? Turned out a little different, didn't it? Tech now seems cynical and bleak. But we can choose tech that is both good and good for us. ryanleesipes.me/lets-leave-t...

We believe the future of technology can be good. That’s why Mozilla Foundation is building a better technology future. One built with care, powered by people, open by design. But we can’t do it alone. Join us and let’s make some good. mzl.la/44ZIdAO #MozillaFoundation #MakeGoodTech

Most mainstream tech is the “fast‑food” of the digital world. Did you know you can choose farm‑fresh, open‑source alternatives that respect your data and the internet ecosystem? Start making the healthy choice today. ryanleesipes.me/organic-tech/

Getting closer to releasing Thundermail, Thunderbird Appointment and Thunderbird Send to the world. Built on open source and open standards - we're working to make a suite of tools that help people break their reliance on big tech (think Microsoft O365 and Gmail). Looking forward to sharing more.

All the speed, power, and customization of Thunderbird in a short and sweet video perfect for viewing (and sharing) on your phone. Help us spread the word to bring Thunderbird everywhere! Thanks again to @freehive.com for their amazing work. #Thunderbird #OpenSource #Email

The beginning of Mozilla, for those of you who haven't ever seen this before, it's a snapshot of a really interesting moment in the history of #opensource software. youtu.be/4Q7FTjhvZ7Y?...
