Firefox 99 Brings These Two Changes for Linux Users
======
Mozillas Firefox is one of the most popular open-source browsers which is the reason it is used as the default browser in many Linux distributions such as Mint and Ubuntu.
Recently, Mozilla released Firefox version 99.0 which brings new security and UI features to Linux.
### Whats new ?
* You can now toggle Narrate in ReaderMode with the keyboard shortcut “n.”
* You can find added support for search—with or without diacritics—in the PDF viewer.
* Added GTK overlay scrollbars
* The Linux sandbox has been strengthened: processes exposed to web content no longer have access to the X Window system (X11).
* Firefox now supports credit card autofill and capture in Germany and France.
In this article, we will be diving into what these are, and expand more on Linux specific changes.
### Gtk overlay scrollbars
This version of Firefox comes with a new sleek thinner design for the scrollbar. The scrollbar also hides, if not in use which provides a more modern and elegant feel to the browser.
![][1]
This feature however is not enabled by default in the Stable release. To enable this feature, go to `about:config` and search for `widget.gtk.overlay-scrollbars.enabled` . By default, this value should be set to `false` but double-clicking it will set it to `true` which will enable the new scrollbars.
![][2]
### Linux sandbox strengthened
This is a security update aimed to isolate the Firefox processes from the rest of the system. A sandboxed environment is one in which applications can run without affecting or interacting with any outside applications. This particular update disables any interaction of web processes with the X server. X server or X11 is the default GUI server used in most Linux distributions.
Snap, Flatpak and Appimage already provide sandboxed versions of their apps which run in isolated containers so if you are a Snap or Appimage user, this is good news. However, there have been [reports][3] of this breaking the hardware acceleration feature.
_Hardware acceleration is a process where applications offload certain tasks to the hardware which results in improved performance and efficient hardware usage. Bad hardware acceleration is one of the reasons for bad battery performance on Linux._
### Wrapping up
All in all, this was Firefoxs last major two-digit update and it is good to see Firefoxs consistent determination for privacy and security. There are some issues that werent addressed in this release such as bugs related to hardware acceleration which will hopefully be resolved in the next update.
This brings us to Firefox 100. The nightly build for Firefox 100 is already out and the full stable version will be released on May 3, 2022. It promises features such as captions in Picture-in-Picture format and improved hardware acceleration. You can try these experimental builds of Firefox by enabling `Firefox 100 User-Agent String` in `about:preferences#experimental` in the nightly builds.

Firefox 99为Linux用户带来了两点改变
======
Mozilla的Firefox是最受欢迎的开源浏览器之一这也是它在许多Linux发行版如Mint和Ubuntu中用作默认浏览器的原因。
最近Mozilla发布了Firefox 99.0版本为Linux版本带来了新的安全和UI特性。
### 更新了什么呢?
* 现在您可以使用键盘快捷键“n”在阅读器模式中切换“讲述”。
* 您可以在PDF查看器中找到对搜索的附加支持带或不带音调符号
* 添加了GTK叠加滚动条
* Linux沙箱已得到加强暴露于Web内容的进程不再有权访问X Window系统X11
* Firefox现在在德国和法国支持信用卡自动填充和捕获。
在本文中我们将深入研究这些内容并进一步扩展Linux版本特定的变化。
### GTK 叠加滚动条
这个版本的Firefox为滚动条配备了一个新的、时尚的和更窄的设计。如果不在使用中滚动条也会隐藏这让浏览器给人以更现代和优雅的感觉。
![][1]
但在稳定版中这个特性默认不启用。开启这个特性,转到`about:config`,搜索`widget.gtk.overlay-scrollbars.enabled`。这个值默认是`false`,双击它将设置为`true`,这将启用新的滚动条。
![][2]
### Linux沙箱得到加强
这是一个安全更新目的是将Firefox进程与系统的其余部分隔离开来。沙箱环境是一个应用可以在不影响任何外部应用或与任何外部应用程序交互的情况下运行的环境。这次的更新禁止了任何Web进程和X server的互动。X server或 X11是Linux发行版的默认GUI服务器。
SnapFlatpak和Appimage已经提供了在隔离容器中运行的App沙箱版本。如果你是一个Snap或者Appimage用户这是个好消息。然而有[报道称][3]这会破坏硬件加速功能。
_硬件加速是应用程序将某些任务加载到硬件的过程从而提高性能和提高硬件使用效率。糟糕的硬件加速是Linux上电池性能不佳的原因之一。_
### 结束语
总之这是Firefox最后一次大的两位数版本号更新很高兴看到Firefox对隐私和安全的一贯决心。此版本中未解决的一些问题例如与硬件加速相关的错误希望在下次更新中得到解决。
这就把我们带到了Firefox 100。每日构建版本的Firefox 100已经发布。完整的稳定版本将在2022.5.3发布。它承诺提供诸如画中画格式的字幕和改进的硬件加速等功能。您可以通过在每日构建中的`about:preferences#experimental`启用`Firefox 100 User-Agent String`来尝试Firefox的这些实验性版本。
