Firefox 可以说是最受欢迎的不基于 Chrome 的开源浏览器，它可用于 Linux、Windows 和 Mac。


众所周知，目前，基于 Chrome 的浏览器在市场份额中占主导地位。但你可能不知道的是，Firefox 早在谷歌 Chrome 出现之前就已经问世了。


准确地说，Firefox 100 的发布标志着，它自 2004 年的发展历程已经有 17 年了。


时间过得好快，一切仿佛就发生在昨天。


### Firefox 100：更新内容

不管你是否喜欢 Firefox 新的发展计划，你都不得不承认，它多年来引入了众多行业领先的功能/技术，这一点令人印象深刻。


Firefox 100 的发布是一个重要的里程碑。但是，这并不是一次大规模升级。


本文中，我将介绍这个版本的主要改进。


#### “画中画”模式改进


![Firefox 100](/data/attachment/album/202205/07/084109sro31rlw1aolnjjg.jpg)


现在，在“画中画”模式下观看 YouTube、Prime Video 和 Netflix 上的任何内容，Firefox 都支持视频字幕。


你只需要在相应的平台上启用视频字幕，它就会继续出现在“画中画”中。


“画中画”字幕不仅支持主流平台，还支持 Coursera 等使用 WebVTT 格式的网站。


#### 语言检测


为了改善用户体验，Firefox 现在可以检测到语言与操作系统偏好不符的情况。


这只会在你安装浏览器后，第一次运行时触发。你可以在系统语言和浏览器默认语言之间进行选择。


#### 滚动条默认不占用屏幕空间


Linux 和 Windows 11 的滚动条默认不会占用你宝贵的屏幕空间。换句话说，当你进行滚动或导航时，滚动条才会做出反应。

你可以在设置中改变这一点（针对 Linux 用户）。如果你是在 Windows 上，Firefox 的视觉效果会跟随你的系统设置。因此，你需要对 Firefox 浏览器进行调整，以符合你自己的偏好。


#### 控制网站外观

对于某些网站，你的浏览器偏好会影响网页的颜色/外观。


为了调整这类网站的体验，你现在可以在设置中设置网站外观偏好，选择浅色/深色、系统或 Firefox 主题。


#### HDR 视频 & 硬件加速的 AV1 视频解码


尽管，对一些用户来说，支持 HDR 视频可能不是什么大事。但我还是要指出，现在 Mac 上的 Firefox 也支持 HDR 了。


截至目前，官方支持仅限于在 macOS 11+ 上浏览 YouTube 网站。当然，你还需要一个支持 HDR 的屏幕。


硬件加速的 AV1 视频解码终于在 Windows 上得到支持，当然，你还得有与之兼容的 GPU（包括英特尔 11 代、AMD RDNA 2 和 GeForce 30 系列）。除此之外，Firefox 在 Windows 上还启用了视频叠加功能，以减少电量使用。


不幸的是，这些并不是针对 Linux 的更新，但应该能帮助跨平台的 Firefox 用户。


#### 其他改进


除了主要的亮点之外，它还包括了以下改进：


* 增加了对多个 Java 线程的分析支持。
* 软重载一个网页将不再导致所有资源的重新验证。
* 有了一个新的链接焦点指示器，它用一个实心的蓝色轮廓取代了旧的点状轮廓。

Firefox is arguably the most popular open-source browser that’s not based on Chrome, available for Linux, Windows, and Mac.

While we know that Chrome-based browsers dominate the market share, Firefox was introduced way before Google Chrome came into existence.

To be accurate, Firefox 100 release marks 17 years of development effort since 2004.

It still feels like yesterday, right?

## Firefox 100: What’s New?

![firefox 100](https://news.itsfoss.com/content/images/wordpress/2022/05/firefox-100-about.jpg)

It does not matter whether you love/hate Firefox’s new development plans, the fact that it introduced numerous industry-leading features/technology over the years is impressive.

Firefox 100 release hits an important milestone. But, it is not a massive upgrade.

Here, I shall highlight the key improvements with this release:

### Improvements to Picture-in-Picture Mode

![firefox 100](https://news.itsfoss.com/content/images/wordpress/2022/05/firefox-captions-100.jpg)

Whenever you watch anything on YouTube, Prime Video, and Netflix in Picture-in-Picture mode, Firefox now supports captions/subtitles for it.

You just need to enable the captions/subtitles for the video in the respective platform and it will continue to appear in PiP.

The support for captions in PiP is not limited to mainstream platforms but also on websites like Coursera that use WebVTT format.

### Language Detection

To improve the user experience, Firefox now detects when the language does not match the operating system preferences.

This only happens when you first run the browser after installation. So, you can choose between the system’s language or the browser’s default.

### Scrollbars Don’t Take Space by Default

The scrollbars on Linux and Windows 11 won’t take your precious screen space by default. In other words, they will be responsive and collapse when you’re focused on scrolling or navigating.

![firefox 100](https://news.itsfoss.com/content/images/wordpress/2022/05/scrollbars.jpg)

You can change this in the Settings (for Linux users). Firefox follows your system setting for visual effects if you are on Windows. So, you would need to tweak that for Firefox to honor your preferences.

### Control Website Appearance

![firefox 100](https://news.itsfoss.com/content/images/wordpress/2022/05/firefox-appearance-tweak.jpg)

For some websites, your browser preferences influence the color/appearance of the web page.

To tweak the experience for such websites, you now can set a website appearance preference in the Settings to choose light/dark, system, or Firefox theme.

### HDR Video and Hardware Accelerated AV1 Video Decoding

HDR Video support may not be a big deal for everyone. But, it is now supported in Firefox on Mac.

The official support exists for YouTube as of now with macOS 11+. Of course, you need an HDR-compatible screen as well.

The hardware-accelerated AV1 video decoding is finally supported on Windows with compatible GPUs (including Intel’s 11th Gen, AMD RDNA 2, and GeForce 30 series). In addition to this, video overlay is also enabled on Windows, reducing power usage.

Unfortunately, these aren’t Linux-specific updates but should help the Firefox users across multiple platforms.

### Other Improvements

In addition to the major highlights, the changes include:

- Support for profiling multiple java threads has been added.
- Soft-reloading a web page will no longer cause revalidation for all resources.
- Firefox has a new focus indicator for links, which replaces the old dotted outline with a solid blue outline.
