Mozilla has launched an experiment where they change the Firefox browser user agent to a three-digit "Firefox/100.0" version to see if it will break websites. The current user agent for Mozilla Firefox version 90 is listed below.

Mozilla has completely removed support for the File Transfer Protocol from the latest release of its flagship Firefox web browser. FTP has been abused in various malware distribution campaigns, some of which involved the compromise of FTP servers to leverage the protocol for payload delivery.
Mozilla this week pushed Firefox 90 to the stable channel with several security improvements, including better protections against cross-origin threats and an advanced tracker blocking mechanism. The open-source browser refresh is currently rolling out with support for Fetch Metadata Request Headers, which means that web applications can better protect users against cross-site request forgery, cross-site leaks, and speculative cross-site execution side channel attacks.
Mozilla has introduced SmartBlock 2.0, the next version of its intelligent cross-site tracking blocking tech, with the release of Firefox 90. The SmartBlock mechanism, introduced with Firefox 87 in March, works to ensure that the Tracking Protection feature and Strict Mode will not break websites when blocking tracking scripts.

The Windows version of Firefox can now automatically upgrade itself to the latest version in the background when the web browser is not running. "Background Update is now available on Windows. This feature will allow Firefox to update, even if it is not running," the Firefox 90.0 Beta release notes read. "Until now, Firefox has only downloaded and installed updates when the user runs it. This means that users that use Firefox infrequently are often out-of-date," according to Kirk Steuber, Platform Engineer at Mozilla.
Mozilla says that Firefox users will be protected against cross-site tracking automatically while browsing the Internet in Private Browsing mode. This is because, starting with the Firefox 89 version released today, the Total Cookie Protection will be enabled by default in Private Browsing windows.
Mozilla advises Firefox users to update to the latest released version to avoid experiencing video streaming issues after Google updates the Widevine digital rights management on May 31. Once Google updates the Widevine private encryption keys and content decryption module on May 31, video streaming services using Google's DRM-protection technology will no longer work with older Firefox versions.
