Windows 7還能再戰！FireFox仍在堅守：支持期限再延半年, Bar Firefox, Purasbar

Floor 1 巨大八爪鱼 3/27/26 14:41

快科技3月13日消息，Mozilla再一次推遲了Firefox 115 ESR版本的終止支持日期，將Windows 7、8及8.1的瀏覽器安全更新服務延長至2026年8月底。

這已是該版本的多次續命，在18個月的累計額外支持周期後，如今又延長了六個月，使其目前唯一仍在維護這些老舊Windows版本的主流瀏覽器。

Mozilla表示，做出這一決定的核心原因，是目前仍有不少用戶堅守在舊版Windows及部分老舊macOS平台上，他們需要一款能夠提供定期安全更新的瀏覽器來保障上網安全。

值得注意的是，Mozilla在聲明中並未把話說死，稱將在2026年8月再次進行評估，暗示如果用戶基數依然龐大，支持期限可能還會繼續順延。

目前Firefox 115 ESR是最後一個支持Windows 7/8/8.1及macOS 10.12-10.14的瀏覽器版本，在Windows 10或macOS 10.15 Catalina及更高版本上的用戶，可以使用最新的Firefox 148。

IT之家消息，Mozilla 昨日（3 月 11 日）宣佈，延長其火狐 Firefox 瀏覽器 115 ESR（延長支持版）對 Windows 7、Windows 8.1 以及 macOS 10.12-10.14 等老舊作業系統的支持，由原定的 2026 年 3 月延長至 2026 年 8 月。

由於 Chrome 和 Edge 等其他主流瀏覽器早已放棄支持上述舊版系統，Firefox 115 ESR 一直是老用戶獲取主流瀏覽器安全補丁的重要途徑。

IT之家援引博文介紹，在 Firefox 115 ESR 的生命周期上，Mozilla 實際上已經表現出了極大的耐心。該版本最初發佈於 2023 年 7 月，原計劃於 2024 年 9 月停止支持。

鑑於當時仍有大量用戶堅守舊版 Windows，Mozilla 先是將截止日期推遲至 2025 年 3 月，隨後又延期至 2026 年 3 月，而現在再次延期至 2026 年 8 月。

開發團隊在官方頁面的備註中明確強調：「我們決定將針對舊版 Windows 和 macOS 的 ESR 115 支持延長至 2026 年 8 月。同時，團隊計劃在 2026 年 7 月重新評估這一決定，隨後再向公眾宣佈最終的停更細節。」這意味着 8 月可能並非絕對的終點，具體走向仍視用戶數據而定。

Mozilla changes plans, extends Firefox support on Windows 7 and 8 once more

Posted on March 11, 2026 by Martin Brinkmann

No one has seen that development coming. After announcing the end of support for its Firefox web browser for Windows 7, 8 and 8.1 starting in February 2026, Mozilla seems to have had a change of heart.

Now, the organization says that it is extending support once again. The information has been published on its What Train Is It Now website, which lists the latest and upcoming Firefox releases.

There, Mozilla writes:

We have decided to extend support to ESR 115 only on Windows 7-8.1 and macOS 10.12-10.14 up to August 2026. We will re-evaluate this decision in July 2026 and announce any updates on ESR 115』s end-of-life then.

Support for Firefox on Windows 7, 8, 8.1 and the macOS versions 10.12, 10.13, and 10.14, is guaranteed until at least August 2026. At least? Yes, as Mozilla may extend support again. In either way, the organization will make an announcement in July 2026 regarding the web browser』s support on the older operating systems.

Firefox 115.x users on these operating systems should receive browser updates, only security fixes and critical bug fixes, as usually via the integrated updating system.

The extension gives users on these old systems access to one of the major browsers, as the other major browser makers, including Google and Microsoft, have stopped supporting the older operating systems for a long time already.

Security updates are guaranteed for another six months at the very least. Good move by Mozilla.

Great news. I was about to consider alternate browsers that support Windows 7 (R3dfox, LibreWolf) and will postpone that heavy intellectual decision until at least July, likely August of this year as it seems. Good. Will allow brains to concentrate on Metaphysics of the after-life, not specifically related to Firefox 🙂

Firefox ESR 140.15 and Firefox 115.40

Make it happen Mozilla.

Anyway, I am already using Redfox (based on Firefox) and Supermium (based on Chromium) on a Windows 7 installation.

I get the impression that Mozilla will be supporting v115.x for quite some time to come. I』m basing my opinion on the 「What』s New」 page where developer options have been added which weren』t present before this latest release. It seems pointless just to add those options for a few months and then drop them.

Also, there』s a significant number of security updates this time around which makes it look like hackers went to town on 115.x assuming that there wouldn』t be anymore updates. So that might have caused some concern over at Mozilla even though they wouldn』t be responsible for this version if users』 systems were compromised.

Still, it』s welcome news in any event.

Firefox extends Windows 7 support till August 2026, cancels previous EOS plan

Mozilla canceled the earlier announced end of support of Windows 7 in Firefox 115 ESR. The operating system, along with macOS 10.12-10.14, will receive updates till August 2026. Interestingly, Mozilla doesn't guarantee that this specific version will work seamlessly on other OSes, including Windows 10.

According to Mozilla's internal statistics, by March 2, 2026, 5.33% of Firefox users will still be running Windows 7. A decision on the future of the ESR branch will be made in June.

Earlier, Mozilla set February 24 as the end of support date for Firefox on Windows 7/8.1/10. The Firefox 115 ESR support cycle initially reached its EOS in September 2024. Mozilla subsequently extended this period on three separate occasions, initially until March 2025, followed by an extension to September 2025, and concluding with a final extension to March 2026. This branch received maintenance for nearly three years, which surpassed the typical one year support duration.

At the same time, Mozilla has updated the actual stable browser version to Firefox 148.0.2.

Firefox 148.0.2 Update

Mozilla has launched Firefox 148.0.2, a maintenance update that addresses five security vulnerabilities. Four of these issues raise from memory management errors, which include buffer overflows and use-after-free vulnerabilities. A specific buffer overflow affects the audio and video playback components within the Android version of the browser. These vulnerabilities pose a risk as they allow attackers to execute malicious code via specially crafted web pages. Additionally, the update fixes a CSS parsing error that enables attackers to bypass Same-origin policy restrictions.

Functional Fixes and User Experience Improvements

This release also corrects several non-security regressions to simplify the browsing experience.
Mozilla resolved an issue where search queries on the New Tab page incorrectly redirected users to the address bar.
The update restores full functionality to web-based text editors, which previously failed to apply formatting like bold or italic styles.
The development team also addressed a specific bug involving YouTube. Previously, the site bypassed autoplay blocks if a user held the Ctrl key, a common occurrence on systems utilizing screen readers. Furthermore, the update fixes an alignment error where absolutely positioned elements shifted to the left instead of remaining centered during page loads.
For pages lacking a "title" tag, the browser no longer displays empty tab-switching recommendations.
Finally, the update restores video quality for Windows users with NVIDIA GPUs who utilize the Video Super Resolution feature.AI-Driven Security Collaboration with Anthropic

Firefox version 148 fixed 60 vulnerabilities, a significant increase from the typical 10 to 20 fixes. This was made possible by a joint security initiative between Mozilla and Anthropic. The project used the Claude Opus 4.6 artificial intelligence model to analyze Firefox's codebase for potential vulnerabilities.

This AI-driven analysis identified 22 confirmed vulnerabilities, including 14 issues with a high-severity rating. The process also uncovered 90 non-security bugs within the code. To demonstrate the technical capabilities of the model, Claude Opus 4.6 generated a functional exploit for the vulnerability identified as CVE-2026-2796.
