The latest release of Firefox 153.0.3 includes several enhancements: Smart Window includes: The suggestion list now shows more results, making it easier to find history and switch to open tabs. (Bug 2019042) The assistant can now answer questions directly using web search results from Exa, instead of handing off to a search engine. (Bug 2046183, Bug […]

In a sign of the times, Firefox's New Tab page could soon include a crossword puzzle from AI-powered news platform Particle. The blog OMG Ubuntu reports: The mini crossword game is updated daily, with puzzles based around recent content Particle's AI has ingested and summarised that day. [After solving the crossword, links appear to related news articles...] If you just want to try the crossword, you access it in any browser via a direct link. While it may look like Mozilla is trying to capitalise on the Wordle craze several years too late, it's part of its strategy to make the Firefox new tab page a discover destination in itself, not just a springboard for new searches. The 'Daily Grind' crossword widget (name subject to change) is just one of several widgets Firefox has (or will get). You'll also find a to-do list, timer, stock checker, world clock, picture of the day, privacy report and new-look weather widget (bigger than the existing one). During the World Cup 2026, Firefox offered real-time match scores and fixture information too... [T]hey aren't mandatory. You can disable the ones you don't want to use, or, if you don't want any at all, turn them all off to hide the widget area itself. A button to 'show fewer widgets' frees up room to allow other distractions (sponsored stories) on the new tab page to show... [Presumably you can also still open new tabs to a blank page...] They're rolling out to users in certain region and locales already. Plus, Mozilla routinely tests new features with a small set of users before they hit stable builds (i.e., the "Allow Firefox to run feature studies" setting). If you don't have widgets in your Firefox build, but you want them, you can manually enable them in Firefox 153 and later from the about:config page. Search for the following master switch and set it to true to enable the widget area: browser.newtabpage.activity-stream.widgets.system.enabled Then, enable the widgets you want to use by searching: activity-stream.widgets.*.enabled However, the usual caveats about "trying things not enabled by default" still apply. Mozilla hasn't set a firm rollout date, though the feature is already documented on its support site. With fortnightly Firefox releases about to start, and a big Nova redesign, chances are we'll all be puzzling over these widgets sooner rather than later.

Longtime Slashdot reader williamyf writes: FireFox 153 was released today. The most important user-facing changes are improvements to PDF handling (you can now merge PDFs and add images to them), and HDR video playback (on Windows, provided HDR is active systemwide). Other under-the-hood changes include browser-wide containers and QWAC support. The full list is in the change notes. But the most important feature is that this version is an ESR and, therefore, defines the ESR feature set for the next year. Why is being an ESR so important, you ask? 1.) ESR, rather than "normal" (a.k.a. Rapid Release), Firefox is the out-of-the-box browser for many important distros, including Debian, RHEL, Kali, Tails, SUSE Linux Enterprise, Slackware, and others. 2.) Many organizations, large and small, standardize on Firefox ESR as their default browser, regardless of the default browser included with their OS. 3.) Firefox ESR is the basis for many downstream projects, such as Waterfox and KaiOS. All these projects will inherit, for a year, whatever ESR brings to the table today. 4.) Many ISVs and SaaS providers, if they certify their wares for Firefox at all, certify for the ESR version only. Please note that ESR 153 will not be offered as an automatic update until two months from now (ESR 140 will still be supported). If you want it now, you will need to download and install it manually. Also of note, ESR 115 will be supported until March 2027. If you use an unsupported version of macOS or Windows (like Windows 7 or 8.x), this is the version to get. However, even Mozilla cautions against running a supported browser on an unsupported OS: "Note that Microsoft ended official support for Windows 7, 8, and 8.1 in January 2023. Unsupported operating systems receive no security updates and have known vulnerabilities. Without official support from Microsoft, maintaining Firefox for outdated operating systems becomes costly for Mozilla and risky for users."

An anonymous reader quotes a report from Linuxiac: Mozilla has released Firefox 152, the latest update to its popular open-source web browser, with updated settings, improved media controls, experimental JPEG XL support, and various platform-specific fixes for desktop and Android. A key update is the redesigned Firefox Settings page, which now features clearer groupings, improved navigation, and a more streamlined structure for easier customization. The release also expands built-in spellchecker support, adding dictionaries for Croatian, English (UK), Georgian, Persian, Slovenian, Tajik, Tamil, Tibetan, Turkish, Welsh, and Xhosa. [...] Importantly, Firefox now offers experimental support for JPEG XL, an image format with improved compression over WebP, JPEG, PNG, and GIF. Users can enable JPEG XL in the Firefox Labs panel within Settings.

Microsoft Corp. today pushed security updates to fix at least 77 vulnerabilities in its Windows operating systems and other software. There are no pressing “zero-day” flaws this month (compared to February’s five zero-day treat), but as usual some patches may deserve more rapid attention from organizations using Windows. Here are a few highlights from this month’s Patch Tuesday.

Two of the bugs Microsoft patched today were publicly disclosed previously. CVE-2026-21262 is a weakness that allows an attacker to elevate their privileges on SQL Server 2016 and later editions.

“This isn’t just any elevation of privilege vulnerability, either; the advisory notes that an authorized attacker can elevate privileges to sysadmin over a network,” Rapid7’s Adam Barnett said. “The CVSS v3 base score of 8.8 is just below the threshold for critical severity, since low-level privileges are required. It would be a courageous defender who shrugged and deferred the patches for this one.”

The other publicly disclosed flaw is CVE-2026-26127, a vulnerability in applications running on .NET. Barnett said the immediate impact of exploitation is likely limited to denial of service by triggering a crash, with the potential for other types of attacks during a service reboot.

It would hardly be a proper Patch Tuesday without at least one critical Microsoft Office exploit, and this month doesn’t disappoint. CVE-2026-26113 and CVE-2026-26110 are both remote code execution flaws that can be triggered just by viewing a booby-trapped message in the Preview Pane.

Satnam Narang at Tenable notes that just over half (55%) of all Patch Tuesday CVEs this month are privilege escalation bugs, and of those, a half dozen were rated “exploitation more likely” — across Windows Graphics Component, Windows Accessibility Infrastructure, Windows Kernel, Windows SMB Server and Winlogon. These include:

–CVE-2026-24291: Incorrect permission assignments within the Windows Accessibility Infrastructure to reach SYSTEM (CVSS 7.8)
–CVE-2026-24294: Improper authentication in the core SMB component (CVSS 7.8)
–CVE-2026-24289: High-severity memory corruption and race condition flaw (CVSS 7.8)
–CVE-2026-25187: Winlogon process weakness discovered by Google Project Zero (CVSS 7.8).

Ben McCarthy, lead cyber security engineer at Immersive, called attention to CVE-2026-21536, a critical remote code execution bug in a component called the Microsoft Devices Pricing Program. Microsoft has already resolved the issue on their end, and fixing it requires no action on the part of Windows users. But McCarthy says it’s notable as one of the first vulnerabilities identified by an AI agent and officially recognized with a CVE attributed to the Windows operating system. It was discovered by XBOW, a fully autonomous AI penetration testing agent.

XBOW has consistently ranked at or near the top of the Hacker One bug bounty leaderboard for the past year. McCarthy said CVE-2026-21536 demonstrates how AI agents can identify critical 9.8-rated vulnerabilities without access to source code.

“Although Microsoft has already patched and mitigated the vulnerability, it highlights a shift toward AI-driven discovery of complex vulnerabilities at increasing speed,” McCarthy said. “This development suggests AI-assisted vulnerability research will play a growing role in the security landscape.”

Microsoft earlier provided patches to address nine browser vulnerabilities, which are not included in the Patch Tuesday count above. In addition, Microsoft issued a crucial out-of-band (emergency) update on March 2 for Windows Server 2022 to address a certificate renewal issue with passwordless authentication technology Windows Hello for Business.

Separately, Adobe shipped updates to fix 80 vulnerabilities — some of them critical in severity — in a variety of products, including Acrobat and Adobe Commerce. Mozilla Firefox v. 148.0.2 resolves three high severity CVEs.

In March 2024, Mozilla said it was winding down its collaboration with Onerep — an identity protection service offered with the Firefox web browser that promises to remove users from hundreds of people-search sites — after KrebsOnSecurity revealed Onerep’s founder had created dozens of people-search services and was continuing to operate at least one of them. Sixteen months later, however, Mozilla is still promoting Onerep. This week, Mozilla announced its partnership with Onerep will officially end next month.

In a statement published Tuesday, Mozilla said it will soon discontinue Monitor Plus, which offered data broker site scans and automated personal data removal from Onerep.

“We will continue to offer our free Monitor data breach service, which is integrated into Firefox’s credential manager, and we are focused on integrating more of our privacy and security experiences in Firefox, including our VPN, for free,” the advisory reads.

Mozilla said current Monitor Plus subscribers will retain full access through the wind-down period, which ends on Dec. 17, 2025. After that, those subscribers will automatically receive a prorated refund for the unused portion of their subscription.

“We explored several options to keep Monitor Plus going, but our high standards for vendors, and the realities of the data broker ecosystem made it challenging to consistently deliver the level of value and reliability we expect for our users,” Mozilla statement reads.

On March 14, 2024, KrebsOnSecurity published an investigation showing that Onerep’s Belarusian CEO and founder Dimitiri Shelest launched dozens of people-search services since 2010, including a still-active data broker called Nuwber that sells background reports on people. Shelest released a lengthy statement wherein he acknowledged maintaining an ownership stake in Nuwber, a data broker he founded in 2015 — around the same time he launched Onerep.
