这是我们在 13.0 系列中的第二个 alpha 版本，代表了从 Firefox 102-esr 到 Firefox 115-esr 的过渡。这是建立在一年的上游Firefox更改的基础上的，因此alpha测试人员应该会遇到问题。如果您发现任何问题，请在我们的 gitlab 或 Tor 项目论坛上报告。foJ免费翻墙网
我们正在进行年度 esr 过渡审计，我们审查 Mozilla 一年的工作，着眼于会对 Tor 浏览器用户产生负面影响的隐私和安全问题。这将在我们将 13.0 alpha 系列转换为稳定系列之前完成。有风险的用户应保留在基于 102-esr 的 12.5 稳定系列上，该系列将继续接收安全更新，直到 13.0 alpha 提升为稳定版。foJ免费翻墙网
我们一直在进行一些主要的重构，并重写到 Tor 浏览器桌面版中的 tor 守护进程控制器代码。我们正在将以前在遗留的 torbutton 和 tor-launcher 组件中找到的各种控制端口接口方法的竞争实现统一和现代化为 Firefox 代码库中的封装 JavaScript 模块。这项工作是必要代码清理的长期计划的一部分，并为支持遗留 tor 守护程序之外的备用 tor 后端奠定了基础。foJ免费翻墙网
为了确保我们发布的二进制文件仅包含我们认为它们包含的功能，我们使用可重现的构建策略。基本思想是，在不同网络上运行构建机器的多个用户独立下拉并构建相同的源代码。然后，我们验证我们最终签名并交付给用户的构建二进制文件是否位对位相同。这让我们有理由相信我们的版本没有受到损害，并且只包含源代码中的功能。foJ免费翻墙网
在 13.0a2 发布周期中，我们启用了为受支持的 Windows 平台生成调试信息的功能，以便更轻松地解决特定于 Windows 的问题。此调试信息包括 PDB 符号（将二进制文件中的地址映射到 Firefox 源代码中的位置）和生成的 C/C++ 标头。不幸的是，标头生成不是确定性的，因此不同的构建器将生成不同的（尽管语义等效）输出。foJ免费翻墙网
这意味着，从整体上看，我们的构建当前不匹配。但是，不匹配的部分仅出现在此调试信息中，该信息与交付给最终用户的实际应用程序是分开的（需要主动查找此不匹配的调试信息，并且仅对调试问题的开发人员有用）。foJ免费翻墙网
Android 版 Tor 浏览器的引导和登录页面中存在各种图形错误，包括未对齐的文本和 Firefox 品牌。首次用户的 Tor 浏览器入门也缺失。这些问题（以及其他问题）正在跟踪 这里， 这里 和 这里.foJ免费翻墙网
Tor Browser 13.0a2 is now available from the Tor Browser download page and also from our distribution directory.foJ免费翻墙网
This release updates Firefox to 115.1.0esr, including bug fixes, stability improvements and important security updates. We also backported the Android-specific security updates from Firefox 116.foJ免费翻墙网
Major Changes
This is our second alpha release in the 13.0 series which represents a transition from Firefox 102-esr to Firefox 115-esr. This builds on a year's worth of upstream Firefox changes, so alpha-testers should expect to run into issues. If you find any issues, please report them on our gitlab or on the Tor Project forum.foJ免费翻墙网
We are in the middle of our annual esr transition audit, where we review Mozilla's year's worth of work with an eye for privacy and security issues that would negatively affect Tor Browser users. This will be completed before we transition the 13.0 alpha series to stable. At-risk users should remain on the 102-esr based 12.5 stable series which will continue to receive security updates until 13.0 alpha is promoted to stable.foJ免费翻墙网
Desktop
Tor Controller
We have been working on some major refactors and rewrites to the tor daemon controller code in Tor Browser for Desktop. We are unifying and modernizing the competing implementations of various control port interface methods formerly found in the legacy torbutton and tor-launcher components into encapsulated JavaScript modules within the Firefox codebase. This work is part of long-term plan of necessary code-cleanup and lays the groundwork for supporting alternate tor backends besides the legacy tor daemon.foJ免费翻墙网
However, all this code-churn does open up opportunity for new behaviour due to fixed bugs or due to the introduction of new ones. If you use Tor Browser in a non-standard/non-default configuration (either via Firefox preferences or custom environment variables) please ensure things are working as expected for your configuration with this alpha release!foJ免费翻墙网
The areas affected by these changes include:foJ免费翻墙网
- configuring Tor Browser to use an external system tor service/daemon
- fetching censorship-circumvention setting using the lyrebird (formerly obfs4proxy) pluggable transport
- any tor functionality that relies on communicating with the tor daemon via the control port (circuit display, onion auth, bridge+network settings, new identity, etc)
Tor PoW
This is also the first Tor Browser release including a tor daemon with the new onion service proof-of-work ddos prevention feature. See Proposal 327 for background and the gitlab issue regarding the implementation.foJ免费翻墙网
Android
This is our first Android release based on the Firefox 115esr series. Some things are still a bit rough around the edges but, to our knowledge, there are not any known regressions to the browser's core functionality.foJ免费翻墙网
Known Issues
Windows
To ensure that we are shipping binaries which only contain the functionality we believe they do, we use a reproducible build strategy. The basic idea is that multiple users with build machines running on different networks independently pull down and build the same source code. We then verify that the built binaries we ultimately sign and ship to users are bit for bit identical. This gives us reasonable confidence that our releases have not been compromised and contain only the functionality found in our source code.foJ免费翻墙网
During the 13.0a2 release cycle, we have enabled generating debug information for our supported windows platforms to make trouble-shooting windows-specific issues easier. This debug information includes PDB symbols (which map addresses in the binaries to locations in the firefox source code) and generated C/C++ headers. Unfortunately, the header generation is not deterministic, and so different builders will generate different (though semantically equivalent) outputs.foJ免费翻墙网
What this means is that, taken as a whole, our builds are not currently matching. However, the mismatched parts only appear in this debug info which is separate from the actual application that is shipped to end-users (this non-matching debug info needs to be actively sought out and is only useful for developers debugging an issue).foJ免费翻墙网
This issue is being tracked here. It will either be fixed before the 13.0 alpha series transitions to stable later this year, or we will disable this developer feature by default to ensure fully matching builds.foJ免费翻墙网
Android
There are various graphical bugs in the bootstrapping and landing pages in Tor Browser for Android including misaligned text and Firefox branding. The Tor Browser onboarding for first-time users is also missing. These issues (among others) are being tracked here, here and here.foJ免费翻墙网
