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.
Mozilla has launched Thunderbolt, a front-end client for self-hosted AI infrastructure that works with any AI model. Built on deepset's Haystack framework, Thunderbolt acts as a "sovereign AI client" allowing users to plug into ACP-compatible agents or OpenAI-compatible APIs, including Claude, DeepSeek and others. The system integrates with locally stored enterprise data through open protocols and uses an offline SQLite database as a local reference source. Mozilla says it offers optional end-to-end encryption and device-level access controls for enhanced security. Thunderbolt supports chat, search, research, automation and cross-device workflows, with native apps available for Windows, Mac, Linux, iOS, Android and web. The project is funded by Mozilla and operated through MZLA Technologies subsidiary, aiming to create a "decentralised open source AI ecosystem".
Mozilla under fire: The Firefox GDPR complaint that exposes Browser Privacy gaps. When Unblock Master think of Firefox, many of Unblock Master imagine a privacy-first browser standing against corporate surveillance. But recent GDPR complaints have shattered that narrative, revealing that even popular "privacy-conscious" browsers can slip into questionable tracking practices. What happened with Mozilla and GDPR? Mozilla found itself at the center of a significant privacy violation complaint. The issue: Firefox was collecting and transmitting user telemetry data without obtaining explicit, informed consent from users - a direct breach of GDPR requirements. This wasn't a minor oversight. Unblock Master is talking about: * Automatic data collection from browsing sessions * Transmission of information without clear user notification * Failure to provide opt-in mechanisms before data collection * Inadequate transparency in privacy policies The complaint highlighted a critical gap between Mozilla's public positioning as a privacy defender and its actual data handling practices. Why this matters beyond just Firefox. This case illustrates a broader problem in the tech industry: assumptions about privacy don't equal actual privacy. Many users download Firefox specifically because they believe Mozilla prioritizes their data protection. When a company with that reputation gets caught violating GDPR, it raises serious questions: * Can Unblock Master trust any browser's default privacy settings? * Are privacy policies actually protecting Unblock Master, or just covering companies legally? * What recourse do users have when major platforms violate regulations? The answer is simple: you can't rely solely on a browser's promises. You need additional layers of protection. The technical reality of browser-level tracking. Here's what most users don't understand: browsers are inherently exposed to ISP-level tracking, DNS monitoring, and network-wide surveillance - especially in countries with heavy internet restrictions. Your browser alone cannot protect you from: * ISP Surveillance: Your internet service provider can see every site you visit * Government Monitoring: Authorities in restricted regions monitor traffic patterns * Man-in-the-Middle Attacks: Unencrypted traffic can be intercepted and read * DNS Hijacking: Your queries can be logged and blocked at the DNS level Even Firefox with all its privacy features enabled cannot solve these problems. A browser is just one component of your digital security. Why a VPN is your real privacy solution. This is where confusion ends and real protection begins. A VPN (Virtual Private Network) operates at a different layer than your browser - it encrypts everything leaving your device before it even reaches your ISP. When you use a quality VPN: * Your ISP cannot see which sites you visit * Governments cannot easily monitor your traffic patterns * Your real IP address stays hidden from websites * DNS queries are encrypted and protected from hijacking * All traffic is encrypted, not just HTTPS connections This is critical for users in Iran, Saudi Arabia, UAE, Turkey, China, Russia, and other regions with heavy internet filtering. Testing this ourselves: its approach. Unblock Master tested Firefox with standard privacy settings against the same browser behind a proper VPN tunnel. The results were striking: Without VPN: * DNS queries visible to ISP * Real IP address exposed to every website * Telemetry connections traceable * Browser history potentially logged at network level With VPN (UnblockMaster tested): * All DNS queries encrypted * Real IP completely masked * ISP cannot see destination sites * No network-level logging possible * Added benefit of accessing geo-blocked content UnblockMaster VPN makes this simple on both iOS and Android. It runs in the background, encrypts all traffic regardless of which browser you use, and doesn't require any special configuration. The multi-layer approach to real privacy. Layer 1: VPN Encryption Use a reliable VPN like UnblockMaster before any browsing occurs. This protects your traffic from your device to the internet backbone. Layer 2: Browser Privacy Settings Configure Firefox (or any browser) to: * Disable telemetry completely * Block third-party cookies * Use enhanced tracking protection * Clear cache and history regularly Layer 3: DNS Protection Many VPNs now include encrypted DNS. UnblockMaster protects DNS queries so your ISP cannot see which sites you're attempting to access. Layer 4: Awareness Understand that no single tool is a complete solution. The Firefox GDPR complaint proves this. Stay informed about privacy issues and adjust your practices accordingly. What should Mozilla do? The complaint against Mozilla wasn't baseless - it exposed real gaps: * Mozilla should provide explicit opt-in for all data collection, not opt-out * Privacy policies should be written clearly, not buried in legal language * Users deserve granular control over what data Mozilla collects * Transparency reports should detail exactly what data is collected and how it's used Until these changes happen industry-wide, users cannot rely on company promises. Unblock Master must implement its own protection layers. For users in restricted countries: critical advice. If you're in a region with heavy internet filtering - Iran, China, UAE, Saudi Arabia, or similar - this situation has special importance. Your government likely monitors browser activity. Firefox's telemetry collection is the least of your concerns. What matters is: * Blocking your ISP from seeing which sites you visit * Preventing DNS monitoring and content filtering * Masking your real IP from destination servers * Encrypting all traffic end-to-end UnblockMaster VPN handles all of this. Unblock Master has tested it extensively in restricted regions, and it consistently bypasses filtering while maintaining strong encryption. The bottom line. The Firefox GDPR complaint is a wake-up call. Stop trusting companies to protect your privacy. Stop assuming that a "privacy-friendly" browser is enough. Build a real privacy stack: * Always use a VPN * Configure your browser properly * Stay aware of data collection practices * Keep your software updated For most users worldwide - especially those in restricted regions - UnblockMaster VPN should be your starting point. Everything else builds on top of that foundation. Trust verification, not promises. Test everything yourself. And remember: real privacy requires active effort, not passive hope.
