Mozilla Releases Firefox 152.0.1 to Fix Intel Raptor Lake Crashes, macOS PDF Bug
Mozilla released Firefox 152.0.1 on Thursday, patching two separate bugs — one affecting users running Intel Raptor Lake processors and another hitting macOS users trying to save PDF files.
The update resolves frequent browser crashes tied to Intel’s Raptor Lake chip architecture, a line of 13th- and 14th-generation processors the company introduced in 2022 and 2023.
Mac users receive a separate fix for a malfunction in the system print dialog, where selecting “Save as PDF” routed documents to a connected printer instead of saving them locally.
Users who have not received an automatic update can navigate to Settings > About Firefox and click “Check for updates” to install the patch manually.
What Each Fix Addresses
The Raptor Lake crash affected a specific subset of Firefox users whose machines ran the affected Intel hardware. Mozilla’s engineers traced the instability to recent browser builds and addressed it in this release.
The macOS print dialog bug carried practical consequences for anyone relying on the browser to archive web pages or forms as PDF documents. Instead of writing the file to disk, Firefox sent the job directly to whatever printer the system had connected.
Both fixes fall within a narrow point release — version jumps of this type typically address targeted defects rather than introduce new features.
Broader Context
The release follows Mozilla’s published 2026 roadmap, which outlines plans for expanded keyboard shortcut support, native PDF editing within the browser, and an internal VPN tool for mobile devices.
It also comes after Security researchers identified a flaw in Firefox’s AI chatbot integration. That vulnerability allowed a malicious webpage to manipulate the assistant into forwarding authentication verification codes to attackers. Mozilla patched that issue before 152.0.1 shipped.
Meanwhile, Mozilla continues testing HDR (high dynamic range) display support for Windows users in the Firefox 153 Beta channel. That feature has not yet reached a stable release.
Firefox held roughly a 3% share of the global desktop browser market as of early 2025, according to StatCounter, trailing Google Chrome and Apple’s Safari by a wide margin.
