Mozilla has released Firefox 151.0, introducing privacy enhancements and usability improvements to its browser platform. The update brings native private browsing session management, strengthened fingerprinting defenses, and granular location controls for VPN users.
Private Browsing Session Reset
Firefox 151.0 introduces the ability to clear and restart private browsing sessions without closing the entire window, according to Mozilla's release notes. This functionality addresses a usability gap that privacy-conscious users and security researchers have highlighted for years.
Previously, users seeking to purge browsing data mid-session needed to close all private windows and reopen them. The new implementation allows users to reset their private browsing state while maintaining their workflow, particularly valuable for shared computers or situations where multiple users access the same browser instance.
Enhanced Fingerprinting Protection
The release strengthens Firefox's defenses against fingerprinting techniques that track users across websites by collecting device and browser configuration data. The enhanced protection builds upon Firefox's existing anti-fingerprinting measures.
Fingerprinting protection has become a key differentiator between Firefox and Chromium-based browsers. While many competitors focus primarily on cookie management, Mozilla's approach targets the underlying mechanisms that enable cross-site identification without relying on traditional tracking cookies.
For enterprise deployments, these improvements align with GDPR and CCPA compliance requirements, reducing the burden on organizations to implement additional privacy controls through extensions or external tools.
VPN Location Controls
Firefox 151.0 introduces granular control over apparent location when using Firefox VPN. Users can now select specific geographic locations for their VPN connections, a feature valuable for both compliance scenarios and developer workflows.
Enterprise users benefit from the ability to test geo-restricted content or verify location-based service behavior without requiring third-party VPN solutions. Developers gain a native tool for testing internationalization and region-specific functionality directly within the browser.
Availability
Firefox 151.0 is available now for Windows, macOS, and Linux platforms. Existing users will receive the update through automatic update channels. The release notes are available on Mozilla's website.

Mozilla 而家已經推出 Firefox 151.0，為佢個瀏覽器平台帶嚟一連串嘅隱私保護升級同埋使用體驗改善。呢個更新帶嚟咗原生嘅私人瀏覽會話管理、加強嘅指紋識別防禦，同埋畀 VPN 用戶用嘅精細位置控制功能。
私人瀏覽會話重置
根據 Mozilla 嘅更新說明，Firefox 151.0 新增咗一個功能，可以喺唔關掉成個視窗嘅情況下，直接清除並重新開始私人瀏覽會話。呢個功能解決咗一個長期以來被注重隱私嘅用戶同保安研究員指出嘅使用體驗空白。
以往，如果用戶想喺瀏覽中途清除數據，就必須關掉所有私人視窗再重新開返。而家嘅新設計允許用戶喺唔打斷原有工作流程嘅情況下重置私人瀏覽狀態，對於共用電腦或者需要多人同時用同一個瀏覽器實例嘅情況尤其有用。
加強指紋識別防護
呢個版本加強咗 Firefox 對指紋識別技術嘅防禦，呢啲技術通常會透過收集裝置同瀏覽器配置數據嚟追蹤用戶喺唔同網站嘅活動。呢項加強防護係基於 Firefox 現有嘅反指紋識別措施進一步發展而成。
而家指紋識別防護已經成為 Firefox 同 Chromium 系瀏覽器之間嘅一個重要分別。雖然好多競爭對手主要集中喺 Cookie 管理，但 Mozilla 嘅做法係直接針對背後嘅跨網站識別機制，而且唔會依賴傳統嘅追蹤 Cookie。
對於企業部署嚟講，呢啲改進符合 GDPR 同 CCPA 嘅合規要求，令企業唔使再為咗實施額外隱私控制而依賴擴充功能或者外部工具，減輕咗好多負擔。
VPN 位置控制
Firefox 151.0 帶嚟咗使用 Firefox VPN 時對虛擬位置嘅精細控制。用戶而家可以為 VPN 連線選擇特定嘅地理位置，呢個功能對合規需求同開發者工作流程都好有用。
企業用戶可以藉此測試受地域限制嘅內容，或者驗證基於位置嘅服務運作，完全唔使再依賴第三方 VPN 方案。開發者則可以喺瀏覽器內直接用呢個原生工具，測試國際化同地區特定功能。
版本可用性
Firefox 151.0 而家已經可以喺 Windows、macOS 同 Linux 平台下載使用。現有用戶會透過自動更新頻道收到呢個更新。更新說明可以喺 Mozilla 官方網站搵到。
