Hello, we’re excited to release the 100th version of Firefox!

Thank you to everyone who got us here: To every employee past and present who played a role in delivering Firefox—thank you for your grit and hard work. To every contributor who championed open source, thank you for turning a browser into a movement!

Finally, thanks to every user of Firefox—thank you most of all. We didn’t get here—17 years and 100 versions later—without your support. Your choice to use Firefox contributes directly to a better web, keeping it open and accessible to all. It is with a profound sense of gratitude and appreciation that we will continue fighting for this global public resource, putting people over profits.

### New

*   We now support captions/subtitles display on YouTube, Prime Video, and Netflix videos you watch in Picture-in-Picture. Just turn on the subtitles on the in-page video player, and they will appear in PiP.
* 我們現在支援 YouTube、Prime Video 和 Netflix 在子母畫面下顯示字幕，只要在網頁影片播放器上打開字幕，它們即可顯示於子母畫面。

*   [Picture-in-Picture](https://support.mozilla.org/en-US/kb/about-picture-picture-firefox) now also supports video captions on websites that use WebVTT (Web Video Text Track) format, like Coursera.org,Canadian Broadcasting Corporation, and many more.
*   子母畫面播放功能新增支援利用使用WebVTT (Web Video Text Track)功能的影音網站，來顯示其影音中的字幕。例如 Coursera.org,加拿大廣播電台等等．．．

*   On the first run after install, Firefox detects when its language does not match the operating system language and offers the user a choice between the two languages.
*   當完成安裝後首次啟動Firefox時，若發現Firefox選用的語系與作業系統的顯示語系不符，將會提示使用者在兩種語系當中選擇其一作為顯示語系。
    
*   [Firefox spell checking](https://support.mozilla.org/en-US/kb/how-do-i-use-firefox-spell-checker) now checks spelling in multiple languages. To enable additional languages, select them in the text field’s context menu.
*   [Firefox spell checking](https://support.mozilla.org/en-US/kb/how-do-i-use-firefox-spell-checker) 現在可以針對多種語言進行檢查了。若要新增其他語言的檢查，可以於文字方框中的右鍵選單選取。
    
*   HDR video is now supported in Firefox on Mac—starting with YouTube! Firefox users on macOS 11+ (with HDR-compatible screens) can enjoy higher-fidelity video content. No need to manually flip any preferences to turn HDR video support on—just make sure battery preferences are NOT set to _“optimize video streaming while on battery”._
*   現在 Mac 版本的 Firefox 在 YouTube 中正式支援 HDR 影片播放了！搭配上支援HDR內容顯示的螢幕，macOS 11+ 的Firefox使用者可以享受保真度更高的影音內容，無須手動切換任何選項即可開啟HDR影像支援。只需要確認系統的電池效能選項『不要』設定為「使用電池時最佳化影片串流」。
> [name=TsunaLu]這個得需要Mac使用者確認一下

    
*   Hardware accelerated AV1 video decoding is enabled on Windows with supported GPUs (Intel Gen 11+, AMD RDNA 2 Excluding Navi 24, GeForce 30). Installing the [AV1 Video Extension](https://www.microsoft.com/en-us/p/av1-video-extension/9mvzqvxjbq9v?activetab=pivot:overviewtab) from the Microsoft Store may also be required.

* AVI 影片的硬體加速解碼功能已支援搭載下列顯示卡的 Windows：Inter Gen 11+、AMD RDNA 2（不含 Navi 24）、GeForce 30。您可能會需要安裝 [AV1 影片外掛程式](https://www.microsoft.com/en-us/p/av1-video-extension/9mvzqvxjbq9v?activetab=pivot:overviewtab)。

*   Video overlay is enabled on Windows for Intel GPUs, reducing power usage during video playback.

* 影片懸浮顯示功能已支援搭載 Intel 顯示卡的 Windows，能在影片重播時節約電量。
    
*   Improved fairness between painting and handling other events. This noticeably improves the [performance of the volume slider on Twitch](https://jrmuizel.github.io/twitch/volume.html).
    
*   Scrollbars on Linux and Windows 11 won't take space by default. On Linux, users can change this in Settings. On Windows, Firefox follows the system setting (System Settings > Accessibility > Visual Effects > Always show scrollbars).

* Linux 及 Windows 11 上的捲軸改為預設不會佔用畫面空間。在 Windows 上，這項設定將遵照系統設定，您可以從「設定→協助工具→視覺效果→永遠顯示捲軸」來設定。
    
*   Firefox now supports [credit card autofill](https://support.mozilla.org/en-US/kb/credit-card-autofill) and capture in the United Kingdom.
    
* Firefox 現在支援英國的[信用卡自動填入](https://support.mozilla.org/en-US/kb/credit-card-autofill)與字元辨識功能。

*   Firefox now ignores less restricted referrer policies—including unsafe-url, no-referrer-when-downgrade, and origin-when-cross-origin—for cross-site subresource/iframe requests to prevent privacy leaks from the referrer.

### Fixed

*   Users can now choose preferred color schemes for websites. Theme authors can now make better decisions about which color scheme Firefox uses for menus. Web content appearance can now be changed in Settings.
    
*   Beginning in this release, the Firefox installer for Windows is signed with a SHA-256 digest, rather than SHA-1. Update KB4474419 is required for successful installation on a computer running Microsoft Windows 7. For more details about this update, visit the [Microsoft Technical Support website](https://support.microsoft.com/en-us/help/4474419/sha-2-code-signing-support-update).
    
*   In macOS 11+ we now only rasterize the fonts once per window. This means that opening a new tab is fast, and switching tabs in the same window is also fast. (There's still work to do to share fonts across windows, or to reduce the time it takes to initialize these fonts.)
    
*   The performance of deeply-nested `display: grid` elements is greatly improved.
    
*   Support for profiling multiple java threads has been added.
    
*   Soft-reloading a web page will no longer cause revalidation for all resources.
    
*   Non-vsync tasks are given more time to run, which improves behavior on Google docs and Twitch.
    
*   Geckoview APIs have been added to control the start/stop time of capturing a profile.
    
*   Various [security](https://www.mozilla.org/security/advisories/mfsa2022-16/) fixes.

### Changed

*   Firefox has a new focus indicator for links which replaces the old dotted outline with a solid blue outline. This change unifies the focus indicators across form fields and links, which makes it easier to identify the focused link, especially for users with low vision.
    
*   New users can now set Firefox as the default PDF handler when setting Firefox as their default browser.
    
*   Some websites might not work correctly in Firefox version 100 due to Firefox's new three-digit number. You can read about it in our blog post [here](https://hacks.mozilla.org/2022/02/version-100-in-chrome-and-firefox/)!
    
    See the Mozilla Support [article](https://support.mozilla.org/kb/difficulties-opening-or-using-website-firefox-100) _Difficulties opening or using a website in Firefox 100_ for possible workarounds you can use. There, you will also find instructions for reporting a broken website so that Mozilla can help fix the problem.

### Enterprise

*   Various bug fixes and new policies have been implemented in the latest version of Firefox. You can find more information in the [Firefox for Enterprise 100 Release Notes](https://support.mozilla.org/kb/firefox-enterprise-100-release-notes).

### Web Platform

*   Support for the WritableStream API has landed. WritableStreams provide an interface for writing streaming data to a sink object.
    
*   Additionally, ReadableStream gained support for the “pipeTo” method, which allows you to connect a ReadableStream to a WritableStream. For example, this would allow you to process data retrieved using “fetch” with the WritableStream Sink object.
    
*   Support for WASM Exceptions is now available. This allows C++ exception handling and unwinding/destructing semantics to be expressed in WASM without an additional JavaScript helper code—and at zero cost to code that does not rely on exception semantics.
