OpenAI announced GPT-6 Cyber, an AI model built for vulnerability research, which uncovered 81 unknown high-severity Firefox flaws and helped patch many of them. In Linux kernel testing, the model flagged 2,308 potential issues, reproduced 1,724 of them, and built privilege-escalation exploits for 948 distinct bugs. OpenAI rated the model's cybersecurity capability as 'Critical,' up from 'High' for its predecessor, and restricted access to select customers in its Daybreak Red program.

Mozilla is trialing a Firefox Nightly feature called Mini Window that lets users pop a tab or page section into a small, always-on-top window with minimal controls. The window hides the address bar and toolbar until hovered, making the content resemble a standalone web app while staying visible above other Firefox windows.

Mozilla has introduced a beta feature called Mini Window in Firefox Nightly that lets users detach a tab, or part of one, into a small floating window resembling a standalone web app. The Mini Window hides the usual browser interface until the cursor hovers over it, revealing only the address bar and basic navigation controls, and it stays on top of other Firefox windows. The feature is currently available only in the Firefox Nightly build.

Researchers report that GLM 5.3, an open-weight AI model released by Z.ai in August, was able to identify and exploit Firefox vulnerabilities during the gap between a security fix being published and reaching users. They found that Firefox versions released between September 17 and October 26 could be compromised this way, with the model building a malicious webpage that silently stole a file from a visitor's computer, at a cost of roughly $1,000 per version. The researchers disclosed the issue to Mozilla, which shipped Firefox 159.0 on October 27, 2026 patching a previously undisclosed vulnerability the model had also used.

Mozilla has added two new features to Smart Window, its opt-in AI browsing tool in Firefox: AI-powered form filling and website monitoring. The form-filling tool uses Google's Gemini 3.1 Flash Lite model to pull context from other open tabs—such as a portfolio or professional profile—to answer form fields beyond basic autofill data like name and address.

Mozilla is rolling out two new capabilities to Firefox's Smart Window AI browsing beta: a tool that auto-fills web forms using data pulled from a user's open tabs, and a 'watch' feature that monitors specified webpages for changes like sales or job postings. The form-fill feature works on text fields with four or more entries and sends source-page data to Google's Gemini 3.1 Flash Lite model, while the watch feature checks pages daily or weekly and notifies users via the Tasks button or desktop alerts. Both features launch first on desktop in the US and Canada, with wider rollout planned for coming months.

A user investigating unstable large downloads in Firefox found that the browser's default network.http.response.timeout setting of 300 seconds, present since Firefox 28, interferes with resuming interrupted downloads. Setting that value to 0 (or a very large number) via about:config reportedly makes large downloads both resumable and more stable, though the fix only works if the server itself supports resumable downloads.
