WebExtensions/RoadMapFirefox57 看点

https://wiki.mozilla.org/WebExtensions/RoadMapFirefox57

摘录我个人感兴趣的重点

Filesystem Access

File system read access is only available through explicit actions, such as drag and drop or input fields. File system write access is only available to the "Downloads" folder. For blob storage we'll provide a library to make using indexeddb easier.

There is no plan to provide read or write access to arbitrary files by Firefox 57.

只能读取用户明确提供的文件，比如通过拖拽、input 表单域
仅提供到 downloads 文件夹的写操作
57 没有支持读写任意文件的计划

Tabs

There is no plan to change the appearance of tabs or interacting with the XUL in any way.

没有计划支持修改标签外观或者与（标签的） xul 交互

Toolbars

This bug (bug 1215064) suggests it will be happening, but it hasn't been assigned to anyone yet. There's some discussion around if this is a good feature or not. The only toolbar left in Firefox is the bookmarks toolbar and there's some pressure to remove that as well. We are not keen on providing APIs, only to have to remove them.

Of all the things in the roadmap, this is the most unclear at this moment. [Last updated May 9th]

目前唯一残存的工具栏是书签栏
谋智想把这个工具栏也干掉
添加操作工具栏 api 的 bug 1215064 目前没人着手
Google 去掉了工具栏相关 api
谋智作为追随者是没有动力自己去添加此功能的

Theming

The theming API will provide static and dynamic access to change background images, font colours. Currently this is similar to "lightweight themes".

There is no plan to support XUL or theming or changes to the UI beyond some basic CSS changes similar to Chrome.

主题 api 提供修改（UI 的）背景、字体颜色，目前和轻量主题差不多
没有计划提供基本 css 调整之外的功能

书签栏没有了书签会去哪

Library / 我的足迹
还有侧边栏啊

不过起码在目前的 photon 计划中
书签栏还是在的

新主题按计划应该不止这样https://www.firefox.net.cn/3g-read-run?tid=54075&fid=6

目前可能是先兼容chrome主题然后慢慢添加其他api，图标应该后面允许新主题修改。

这是 57 的 webextensions 的目标
和主题包不同
而且可能到了 57 以后还有调整？（也可能不会

而主题包也有可能计划有变
从目前的原型来看 https://docs.google.com/document/d/1ueD6V7aLLTuc1GAOxxQYcwl2HR-k62HHu3q8knTJ4FU/pub
就只有涉及基本的 css 调整

FAQ 的最后更新还是 3 个月前
https://wiki.mozilla.org/Add-ons/Themes/FAQ

bug 1306671 倒是关掉了
现在在 bug 1330328 实现
