The open-source, cross-platform Mozilla Firefox 101 web browser is now available for download as a minor update that introduces a handful of tweaks and various improvements.

Firefox 101 is a fairly minor update, so don’t expect any major changes. Probably the most interesting change in Firefox 101 is the fact that Mozilla has reimplemented the dialog prompt to save or open files, which was removed in Firefox 98 when Mozilla implemented an optimized download flow.

Now users will be able to re-enable this dialog prompt via a new option added right after the General > Apps section in Settings. There are actually two new options added here, namely “Save files” (default) and “Ask whether to open or save files”.

Of course, users will be able to configure Firefox to manage MIME types for different files, such as saving a file or opening it with an application installed on your computer. Mozilla details this change in detail in a support article.

Other changes in the Firefox 101 release include support for prefers-contrast media query to allow websites to detect whether the user has requested that web content be displayed with higher or lower contrast, the ability to use Magnifier in Firefox for Android to position the cursor in forms on web pages on Android 9 or later, as well as the latest security patches.

For web developers, Firefox 101 also introduces three new CSS window sizes, namely small (s), big (l) and dynamic (d), correct parsing of AV1 codec parameters in media support queries, activation of WebDriver BiDi protocol by default, as well as many other detailed changes here.

Mozilla plans to officially announce the Firefox 101 web browser tomorrow, May 31, 2022, but you can download the final version now as binaries for GNU/Linux, macOS, and Windows systems from the official FTP server.
