新版的前端很好呀，又实用又好看

如果无法选择抛弃当前手机，你可以选中“关闭 miui 优化”，这样你的手机会比较像 android 一些

@silymore
倒不是这个意思。

通过收集用户信息换取屏蔽网页上广告的做法也大有人接受，比如 Chrome 平台最流行的去广告扩展 Adblock for chrome(它不是十几年前那个还只是 Firefox 扩展的 Adblock plus 的前身)就可能是这种类型，之前有人指控它收集用户的浏览历史。

而是希望它说清楚自身的定位，把话说明白，特别是它自己提供的文字材料里互相冲突的部分。

列举上面提到的扩展的部分隐私政策(全文进链接)：


ublock origin:

https://github.com/gorhill/uBlock/wiki/Privacy-policy

"
uBlock Origin has no home server.
uBlock Origin doesn't embed any kind of analytic hooks in its code.
The only time uBlock Origin connects to a remote server is to update the filter lists and other related assets
"


Privacy Badger:

https://www.eff.org/code/privacy/policy

"Generally, we do not store personally identifiable information (PII), including the IP addresses of users, when collecting bug reports or research data. However, on occasion, we may store IP addresses for limited debugging purposes. "

“ we may disclose personally identifiable information about you to third parties in limited circumstances, including: (1) with your consent; or (2) when we have a good faith belief it is required by law, such as pursuant to a subpoena or other judicial or administrative order.”

“ Sharing of datasets:
From time to time, we may share datasets derived from our technology projects with research partners working on topics related to Internet security, censorship resistance, privacy or other public policy objectives. We may also publish datasets in an effort to further these objectives. The datasets we may share or publish will not intentionally contain PII and we will evaluate whether further sanitization or aggregation of data is necessary to reduce the likelihood that inferences about identifiable individuals' activities might be made from the published dataset. Because anonymization is an algorithmically complex problem, we cannot promise that it will be flawless or attack-proof. When we believe that a dataset may contain information that is especially sensitive or vulnerable to de-anonymition, we will not publish it, and if we share share such data with research partners, we will place them under a contractual obligation to keep the dataset confidential and avoid de-anonymization.”

注意，它把 IP 地址当作 PII，但你们不是


Adblock Plus:

https://adblockplus.org/privacy

“ Extension update checks

Your browser periodically checks for updates of all your extensions including Adblock Plus. Some general information - browser version, extension version, operating system, date of last update and your IP address - are transmitted during an update check. Updates for Adblock Plus for Android and Internet Explorer are handled by the AdblockPlus.org website and the data transmitted is subject to its privacy policy. Updates to Adblock Plus for Firefox are handled by the Addons.Mozilla.Org website and are subject to the Firefox Privacy Policy. Updates to Adblock Plus for Chrome are handled by the Google Web Store website and are subject to the Google Privacy Policy. Updates to Adblock Plus for Opera are handled by the Opera Add-ons website and are subject to the Opera privacy policy. Updates to Adblock Plus for Safari are handled by the Safari Extensions website and are subject to the Apple Privacy Policy.

Subscription downloads

If you add filter subscriptions to your Adblock Plus installation, the subscription will be requested to regularly retrieve updates. Every update results in the hosting website receiving your IP address as well as some general information like your Adblock Plus version, browser and browser version. The processing of such data is not controlled by eyeo and is subject to the respective privacy terms of the provider of the website in question.

Furthermore, if a subscription download fails on several consecutive occasions, the updated address of the filter list is requested from the AdblockPlus.org domain. The data transmitted includes the Adblock Plus version, subscription address and any information about the error encountered. This data is used to identify issues that have not been reported by subscription maintainers and is subject to this Privacy Policy.”

比如你们的隐私条款里有这些明显不合适、令人怀疑动机的内容：


Information Cloudopt may collect:
- Information Cloudopt receives from other sources. Cloudopt works closely with third parties (including, for example, business partners and sub-contractors in technical, payment and delivery services, advertising networks, analytics providers, search information providers, credit reference agencies) and may receive information about you from them.

Cloudopt uses information about you in the following ways:

- to deliver relevant advertising to you.

- NPII. Cloudopt will use this information to test, develop and improve its products and to produce analytical, statistical and tracking data that will help it:
- to understand how the site is accessed and used;
- to administer the site and for internal operations, including troubleshooting, data analysis, testing, research, statistical and survey purposes;
- to improve the site to ensure that content is presented in the most effective manner for users; as part of Cloudopt ’ s efforts to keep the site safe and secure;


既然你们的产品是“通过拦截常见第三方跟踪系统保护您的隐私。”，那为什么自己要做这种事情？

@cloudopt 你们的产品和 ublock origin/ ublock origin + privacy badger 相比：

1，有什么异同？
比如 ublock 是基于 adblock plus 的超集规则的静态列表进行内容拦截+隐藏(css)的，而 pb 则有自动识别追踪用代码（域名）并加以拦截的能力。

2，覆盖范围有哪些差别？

3，上传哪些数据，其必要性在于哪里，上传的数据用于哪些用途，会把用户标识和其它信息关联吗？
比如 ghostery 的出资者是广告公司，它通过研究用户的屏蔽为广告公司服务。

再比如
3.1 书签+搜索是 omnbox 自带的功能，为何需要由你们重新制作一番？

3.2 你们的信誉功能和扩展 wot 相比，有什么特色？

可以看看 adblock plus 与 ublock origin 的文档，后者支持的过滤选项比较多

它是说线程未使用（没有任务）长达 60 秒后抛弃。
楼上的 @zhaohui318 说得很清楚

youtube 的 1440p 的单位像素的码率比蓝光低得多。
因此用 2160p 视频降采样成 1440p 能明显提高画质。单位码率足够高时，这个区别就会非常小，甚至反超（降采样算法可能会产生损失）。

这也就是为什么蓝光碟片（ 30GB+）的 rip 虽然也是 1080p，但体积降低到了 5 ～ 10GB

不建议使用此品牌的联网才能工作的产品，你已经提到它的坑了。

亡羊补牢：
使用 TOTP 协议的两步验证时，(必须)做好备份工作，比如有备用方案 /TOTP 验证的种子能导出

一般来说在注册 TOTP 时，肯定会给你提供一个复杂的恢复密码，或者一组备用验证码等备用手段

更换成 CBB 分支稍微好一些

@ihainan onedrive 同步到本地是默认的

chrome 承担的商业责任比 firefox 更多，但在架构上后者在往前者靠拢：

多进程，沙盘化（ electrolysis 项目）用的就是 chromium 的库
用 webextension api 替代自有的扩展用接口
下一版的 ui 比目前的 astralis 更接近 chrome 的样式

nas 强调数据在线或者是近线的。

一般人虽然有数据可控安全（注意是对个人而言的）的要求，但通常可以容忍数据是离线的（只在需要时使用）

三星有提供相关的接口，这些接口不属于 android 的 api
