We got you 🔥
if you don't have at least 3 random beverages on your desk and 36+ open tabs with no memory of having opened them, are you even browsing?
Ohhh this is a good one to suggest on our feedback platform called Connect! connect.mozilla.org
We appreciate everyone's feedback here! It's important to note that these features are optional, off by default, and local models are downloaded if the feature is used. This won't please everyone but we do want to provide more context into how we're approaching it.
We hear your concerns, and that’s why our approach is different. We run AI features on your device so data remains local, and you can remove downloaded models anytime. We believe in giving consumers a choice: you decide if, and how you want to use AI.
🧡🔥
The main point here is that we're very close to a duopoly with Google and Apple. Agreed, this isn't easy to explain so appreciate the community coming through with feedback. We'll continue discussing this on our channels so we can keep the conversation going.
1. Chromium is used interchangeably with Blink (in fact, most people don't know what Blink is) 2. We were referring to Safari, which is part of Apple's closed ecosystem. But you're right. 3. Our independence enables innovation that Google wouldn’t fund on its own like ad blockers
You're right. We were referring to Safari itself, which is part of Apple's ecosystem. This is what we meant by ‘closed' and with limited flexibility. We posted an update in thread but appreciate you calling this out.
Safari itself is part of the Apple ecosystem, and that’s what we meant when we said ‘closed' and with limited flexibility. Appreciate those who are fairly pointing out that WebKit is open source.
Hm tell us why?
Imagine having an actual choice to change it support.mozilla.org/en-US/kb/cha...

So using Firefox and supporting Gecko-based browsers is pretty defiant. What you’re saying is: I believe the internet belongs to all of us, not just a select few. Thanks for coming to our ted talk! Here’s a flame 🔥 7/7
Also, it’s not just about us. Our browser engine helps power other independent browsers giving you even more choices. 6/7
A good example of this are adblockers! Having a seat at the table means giving you a real choice so you can browse on your terms. 5/7
So why does that matter? A few reasons: less options means only 1 or 2 companies are deciding how you browse online and what features get developed (or not) 4/7
So what’s left? It’s Firefox. We run on a different engine called Gecko. It’s open-source and independent. 3/7
Most browsers are built on Chromium (aka Google’s engine). The other big player? Safari. It runs on WebKit, a closed-source browser engine with limited flexibility. 2/7
Imagine a world where there's only one brand of car. Yeah... not great. That’s basically what’s happening with your browser. Let’s do a deep dive 👇1/7
Yay! It's the first Firefox release since I've joined the team, so let's take a look at some of the new developer-facing features in Firefox 142… 🧵
Firefox 142 is out. Still not the answer to life, the universe, and everything… …but it will fix your tab groups 😌
🔥🔥🔥
We still love browser stuff though 🔥
Who do you trust outside the algorithm? For Substack writer and internet decoder Ochuko, the answer is simple: her group chats. Today’s #dailydefiance challenge: Check your chats before your feed 👀 mozillasidebar.substack.com/p/gen-z-algo...
Thank you for your support! 🔥
🔥🔥🔥
Most people just use the browser that came with their device but hear us out… What if you didn’t ? This month we'll be posting about small acts of daily defiance that help us take back control. Share yours with #dailydefiance and we'll RP our faves 🔥
@firefox.com send tab to device feature is so very useful. For example: get a text message on phone with link to "follow my delivery" UPS tracking. Open link on mobile firefox, hit share, and send to desktop instance of firefox. Kudos to firefox team for that one!
it's your friendly neighborhood internet fox reminding you that adblockers still work over here 🔥
Our idea of fun: open-source everything and curling up around a globe
This seems personal
"you look happier." thanks, we stopped accepting the default and life has never been better 🔥
we can relate 🫠
😳
wooooah! wait we need to promote this brb
This is your sign 👀
"what's your favorite horror movie?" oh we don't know, maybe when we had 89 open tabs and we couldn't find which one was playing audio 😭
firefox 141 tabs sort themselves address bar knows math linux builds less hungry autofill expanded to 🇧🇷 🇪🇸 🇯🇵 just browser
Our favorite thing is seeing people create. This is amazing 🧡
"why can't you concentrate?" maybe because our nervous system is in a group chat with 14 browser tabs and 3 slack channels 🫠 blog.mozilla.org/en/firefox/m...
The news we needed
Hey Bluesky friends, what kind of content would you like to see more of on our page? 🤔
🫡🔥
The little crunches 🥹
Pro tip: if you’re using vertical tabs, turn on “expand sidebar on hover” you're welcome
Bet you didn't know that we speak over 400 languages 😌 all thanks to thousands of volunteer localizers around the world who make Firefox feel like home blog.mozilla.org/en/firefox/f...
Tetris, no updates, full batteries. Life really was the main menu
thanks 🤝
Accidentally opened the same tab 7 times? Right-click any tab → choose "close duplicate tab" and boom 🔥
Excellent taste 🔥
🤖 Not that I would want a AI-chatbot inside the browser, but I am very thankful atleast they would let me pick what service I would like. More companies would adopt this strategy if they where consumer first. Thanks @firefox.com
🫡
we're honored 🔥
Multi account containers for the win because mixing work tabs with 3am rabbit-hole browsing tabs is a recipe for disaster 😅
New week, new Firefox theme. Head over to tools → add-ons & themes → choose a theme that matches your mood 🔥
we can’t wait for this!
We're not saying we opened 6 tabs for flights and snacks while writing this blog... but we're also not not saying that 😅https://blog.mozilla.org/en/firefox/travel-features/
We appreciate you! 🫶
😅
should we make posters 🤔
uhhh thanks?
🥹 thank youuuu
It's ok we get it 😢
👏
New Firefox alert! • Resize pinned vertical tabs for a cleaner, quicker view • Hide the extensions shortcut for a cleaner toolbar. Still accessible via the menu. • Unload tabs by right-clicking to free up memory & boost performance 📄 Full release notes www.mozilla.org/en-US/firefo...
A tab group for local journalism, another for burrito rankings. A well-balanced browser. @lataco.bsky.social gets it mozillasidebar.substack.com/p/the-most-l...
Agreed, we need more.
no plans on June 26th
just a reminder: Firefox for Android supports over 1,000 extensions 🔥
Hi! We sent this to our support team and they're looking into it so we can reach back out once we know more.
thank you ♥️
we're kinda late here but our browser engine is called Gecko, and you can use any search engine you'd like.
Ricky is a real one
we respect your choices 🫡
🔥🦊
Firefox isn’t the default. It’s a choice that says you believe in an open web.
The lore runs deep with this one
hmmm interesting 🤔
🦊😉
looks like we’ve got weekend plans
A Haiku: You deserve better You should download Firefox now Five more syllables
So cool! Congrats!!
Fighting crime or fighting zombies, she really can do it all
Our address bar just got smarter. Run commands, search your tabs, switch engines, and clear your history all without leaving the bar.
Red pandas are also known as firefoxes 🔥
Setting a reminder on our calendar asap
Found: the quirky chatbot lost since the '80s… because sometimes the internet remembers cool stuff. More curious reads if your feed needs a boost👇 open.substack.com/pub/mozillas...
appreciate you 🫶
fun fact: they're built on the gecko engine made by yours truly. this is why an open web, built by communities, not corporations, is so important.
psssst every time you browse online you can support an open web by using Firefox 🔥
and we're just firing up 🔥
Thank you 🫶🔥
yeaaa... 😅
