New Alpha Release: Tor Browser 16.0a2
嗯，用户让我用中文总结一下这篇文章，控制在100字以内，而且不需要用“文章内容总结”之类的开头。直接写描述就行。 首先，我得通读整篇文章，抓住主要内容。文章是关于Tor Browser 16.0a2版本发布的，提到了安全更新和一些问题修复。还有提到这个版本是Alpha测试版，可能有bug，不适合普通用户使用。 然后，用户需要的是简短的总结，所以我要提炼关键点：版本发布、安全更新、Alpha测试版提醒、主要问题修复（比如网站加载失败和APK大小问题）、以及对贡献者的感谢。 接下来，控制在100字以内。我得确保每个要点都涵盖到，但又不冗长。可能需要合并一些信息，比如把多个问题修复合并成一句话。 最后，检查语言是否简洁明了，直接描述内容，不加任何开头或结尾的修饰。 </think> Tor Browser 16.0a2发布，包含Firefox的重要安全更新。此版本为Alpha测试版，可能存在影响稳定性和隐私的bug。主要修复包括网站加载失败和Android APK过大问题，并感谢社区贡献者支持。 2026-2-4 00:0:0 Author: blog.torproject.org(查看原文) 阅读量:3 收藏

Tor Browser 16.0a2 is now available from the Tor Browser download page and also from our distribution directory.

This version includes important security updates to Firefox.

⚠️ Reminder: The Tor Browser Alpha release-channel is for testing only. As such, Tor Browser Alpha is not intended for general use because it is more likely to include bugs affecting usability, security, and privacy.

Moreover, Tor Browser Alphas are now based on Firefox's betas. Please read more about this important change in the Future of Tor Browser Alpha blog post.

If you are an at-risk user, require strong anonymity, or just want a reliably-working browser, please stick with the stable release channel.

Finally, we would like to thank the following community members for their contributions this release:

Catching up With Rapid-Release

Over the past few months we have been sprinting to catch Tor Browser Alpha up with Firefox Rapid-Release. Tor Browser Alpha is now based on Firefox 147 and the rebase to Firefox 148 is now underway. We also have a massive head-start on our bugzilla triage and have already flagged dozens of upstream patches which we will need to investigate further for ESR 153.

Unfortunately (though somewhat expectedly), all this progress has introduced some bugs and blockers.

🤖 Android APK Too Big

The upstream changes from Firefox pushed us over the approximate 100 MB size limit imposed by the Google Play Store on our Android packages. To trim off some more bytes and get us under the threshold we back-ported usage of the terser JavaScript minifier (to reduce the size of the JavaScript source) and we now conditionally compile out preferences for unrelated platforms (i.e. we no longer ship preferences on Tor Browser Android which only affect Desktop).

This issue has been resolved in tor-browser-build#41688.

🛑 Websites Failed to Load

In Tor Browser 16.0a1 we discovered an intermittent issue where websites would fail to load after bootstrapping. This has a resulted in the browser being essentially unusable for a significant number of testers.

The proximal cause for this that the NoScript extension would be put to sleep and unable to respond to requests made by the browser content process. Our engineers discovered this seems to have been fallout over upstream changes around how WebExtensions interact with the browser in permanent private-browsing mode. For now, we have worked-around this bug with patches to both NoScript and Tor Browser. When we know more, we will open an issue upstream with Mozilla.

This issue has been resolved in tor-browser#44398.
