Scheduled for an official launch on October 24th, the Mozilla Firefox 119 open-source web browser is now available for download and it’s time to take a first look at its new features and improvements.
Firefox 119 comes with an improved Firefox View feature that now offers more content, such as recently closed tabs and browsing history, which you can sort by date or site, as well as support for viewing all the opened tabs from all windows, and all the tabs from all of your synced devices.
Firefox 119 also appears to let you import some of your Chrome extensions (if they’re available for Firefox, of course) when migrating your data from Google Chrome, adds support for the Santali (sat) language, and support for remembering recently closed tabs between sessions even if automatic session restore is not enabled.

Other than that, this new Firefox release disables media sniffing by default for top-level documents that are served as application/octet-stream type. Due to this change, Firefox will now download these file types instead of attempting to play them.
Firefox 119 also addresses an issue that caused unexpected jumps in the scroll position when navigating the Facebook website. Various security issues have been addressed as well in this release (check here for more details).

As mentioned before, Mozilla plans to officially announce Firefox 119 tomorrow, October 24th, 2023, but you can download the binaries right now from the official download server if you’re using Firefox this way on your GNU/Linux distribution.
