Firefox 152 debuts with new-look Settings, odd way to mute tabs. Mozilla has released Firefox 152 with revamped Settings and faster ways to share web content - plus, a peculiar way to mute noisy tabs. The update is available from today (15 June, 2026) on Windows, macOS and Linux, as well as for Android and iOS (mobile versions have different features and are not covered in this post). Firefox 152's headline change is the revamped Settings page. Omgubuntu knew this was coming as Mozilla's been teasing it for over a year. The company says the new look offers "streamlined organisation, clearer groupings, and improved navigation for easier customisation". Since many users find rifling through their web browser's settings daunting and confusing (especially as more customisation options get added), this is a welcome refresh. Good design is as much about clarity and logic as it is about simply looking pretty. But forewarn your muscle memory as the 'General' page has been removed and its options moved into relevant areas like Appearance, Accessibility, etc. If you can't find where a setting is you can use the search bar to locate it. The new-look Settings in Firefox 152 is visually tied to the upcoming Firefox Nova redesign, which also features lots of rounded corners, cards with thin borders, gradients and white space. What else is new in Firefox 152? Firefox 152 now makes it easier to selectively disable tracker blocking in private browsing windows. This is useful if an element or part of a web pages looks broken or can't load with trackers blocked (like an Instagram embed in a news story, for instance). Linux and Windows users can now copy links from the tab context menu (right-click a tab, mouse to Share > Copy Link) without having to focus the tab first. It works when multiple tabs are selected too, so you can copy all selected links at once. Firefox also introduces a "Send tab" toolbar button, albeit not enabled by default. To add it, go to More Tools > Customise Toolbar and drag it from the button palette on to the toolbar. Wondering what that 'peculiar' new way to mute tabs in Firefox 152 is? The browser lets you type - yes, type - "mute", "shush" or "sssh" in the address bar to reveal a button you can then click to silence all tabs in all open Firefox windows which are playing sound. Convenient? Probably. I don't tend to keep a cacophony of audio in play, and reaching for my keyboard's mute sound or pause media keys would be a faster way overall. Options are good - especially ones which enable you to role-play as a librarian... On the topic of words (tangental segue klaxon), Firefox 152 bundles in built-in spellchecker dictionaries for builds downloaded in Croatian, English (UK), Georgian, Persian, Slovenian, Tajik, Tamil, Tibetan, Turkish, Welsh and Xhosa. * Missing Paste option when editing text on some sites (like eBay) restored * Images dragged from Firefox on to the desktop now save reliably * On multi-monitor setups, About Firefox opens on the display with Firefox * Zoom using keyboard or mouse at smaller increments * PDF downloads open in background tabs if source tab closed * Right-to-left text arrow-key selections move in correct direction * WebAuthn Related Origin Request to use Passkeys on multiple domains Plus, the usual clutch of web compatibility and developer-focused buffs. It adds action button support for Web Notifications, supports the-sizing property and adds the unadjustedMovement option to the Pointer Lock API so sites can get 'raw mouse-movement data'. Plus, a fresh batch of security patches to keep its collective web browsing as safe as it can be. No new AI features in this update, but Firefox's new Smart Window browsing mode is still in development. You can test it as a beta feature by flipping the relevant about:config value on (search 'Smart Window' to find it). How do I update to the new version of Firefox? You can download Firefox 152 from the official website for Windows, macOS and Linux, with builds available for Intel/AMD and ARM64 devices. If you already use Firefox, update to the newest version the same way you updated to the last - automatically, in most instances. On Windows and macOS, updates are come as in-app updates downloaded in the background and applies on relaunch. On Linux, your distro's package manager will serve up the update. On Ubuntu, that comes from the Snap Store unless you use the Mozilla APT repo.

Fix your GTM process: lessons from Twitch, Meta & Mozilla. Your marketing teams aren't aligned - and it's killing your launches. That's the uncomfortable truth Christina Lang has seen play out at every scale, from 20-person startups to 5,000-person enterprises. In this episode of Run The Play, Christina - former VP of Global Marketing at Mozilla, with senior marketing leadership roles at Twitch and Meta - breaks down the exact go-to-market process she used to fix cross-functional chaos at some of the biggest platforms in tech. This conversation is essential for anyone building or fixing a go-to-market strategy. The real problem isn't process - it's communication. David and Christina worked side by side at Twitch during its post-Amazon acquisition growing pains. Siloed teams, competing priorities, and a lack of shared language were derailing launches left and right. But when Christina diagnosed what was actually going wrong, she discovered the root cause wasn't a missing process doc or a broken workflow - it was communication. Teams weren't failing because they didn't have a playbook. They were failing because they didn't have a shared understanding of what mattered, who owned what, and how decisions actually got made. Christina rebuilt the GTM system from the inside out, and the approach she walks through in this episode is something any marketing leader can apply - whether you're inheriting a broken process or building one from scratch. Find the power center first. One of the most tactical takeaways from this conversation is Christina's advice on where to start when you're the new operator walking into organizational chaos. Her answer: find the power center. Before you redesign a single workflow, figure out where decisions actually get made in the organization. It's not always where the org chart says it is. Understanding the real power dynamics - who influences whom, whose buy-in actually matters, and where resistance will come from - is the difference between a process that sticks and one that gets ignored. Earn buy-in without putting your name on it. Christina's philosophy on change management is refreshingly honest: the best process operators never get praised - and that's the point. She explains why the most effective way to drive organizational change is to make other people feel like the new process was their idea. It's not about ego. It's about adoption. If you slap your name on a new GTM framework and mandate compliance, you'll get passive resistance. If you embed your ideas into existing conversations and let stakeholders shape the output, you get lasting change. This approach connects directly to how fractional CMOs operate - driving transformation from within, not from above. The three-step GTM framework that actually works. Christina's non-negotiable GTM framework simplifies the entire go-to-market process down to three stages: planning, alignment, and launch. That's it. She argues that most organizations over-complicate GTM with too many stages, too many approval layers, and too much documentation. The result is a process so heavy that teams route around it - which means you end up with no process at all. Her key distinctions: decide who actually needs approval authority versus who just needs visibility. Not everyone needs to be in the room for every decision. And documentation matters - but over-documentation kills adoption. The goal is a system lightweight enough that people actually use it. Micro changes beat big transformations. Perhaps the most powerful concept in this episode is Christina's philosophy of "micro changes." Instead of announcing a big process overhaul that triggers organizational antibodies, she advocates for small, incremental adjustments that let you transform a system without anyone noticing. By the time people realize the process has changed, they've already adopted it. It's change management for people who've been burned by change management. What you'll learn in this episode: * How Christina diagnosed GTM dysfunction at Twitch during its post-Amazon acquisition phase * Why the first move in any new role should be finding the organization's real power center * The three-step GTM framework (planning, alignment, launch) that replaces bloated processes * How to earn buy-in without putting your name on the change * Why documentation matters but over-documentation kills adoption * The "micro changes" philosophy for transforming processes without triggering resistance * Who actually needs to be in the room - and who just needs visibility Listen to the full episode above, or find Run The Play on YouTube.

Mozilla has discovered 271 security vulnerabilities in Firefox 150 using early access to Anthropic's Mythos Preview AI model. The findings represent a significant increase from the 22 bugs detected by Anthropic's Opus 4.6 model in Firefox 148 last month. Firefox CTO Bobby Holley said Mythos is "every bit as capable" as the world's best security researchers, whilst eliminating the need to "concentrate many months of costly human effort to find a single bug". He believes AI tools like Mythos tilt the cybersecurity balance towards defenders by making vulnerability discovery cheaper. Anthropic released Mythos Preview to a limited group of industry partners earlier this month. Mozilla CTO Raffi Krikorian argues such tools are particularly crucial for open source projects, which often rely on insufficient volunteer maintenance for security.
