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.

On top of that, this release adds support for editing PDF files by adding images to them, in addition to adding text and drawing. According to Mozilla, Firefox now also lets you add Alt Text to a PDF document when adding images.

Some security and privacy enhancements are also present in Firefox 119, such as Encrypted Client Hello (ECH) support for a more private browsing experience, partitioning of Blob URLs to mitigate potential tracking vectors that third-party agents may use to track you.

In addition, Firefox 119 adds font fingerprinting protection by restricting the visibility of fonts to sites to only system fonts and language pack fonts when using the ETP (Enhanced Tracking Protection) strict mode, and updates the Storage Access API web standard to improve security and also mitigate website breakages while further enabling the phase out of third-party cookies.

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).

For web developers, this Firefox release adds credentialless support in Cross-Origin-Embedder-Policy, support for ARIA reflection for simple attributes and default Accessibility Semantics for Custom Elements, support for a fallback parameter to the CSS attr() function, and easier grouping of items in an array by using the Object.groupBy() or Map.groupBy() methods.

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.

Update 24/10/23: Mozilla officially released Firefox 119 and I’ve updated the article with the rest of the changes included in this version. For more details, you can also check out the release notes.
