Firefox 94.0.1 [Update]

Firefox is a fast, full-featured Web browser. It offers great security, privacy, and protection against viruses, spyware, malware, and it can also easily block pop-up windows. The key features that have made Firefox so popular are the simple and effective UI, browser speed and strong security capabilities.

Firefox has complete features for browsing the Internet. It is very reliable and flexible due to its implemented security features, along with customization options. Firefox includes pop-up blocking, tab-browsing, integrated Google search, simplified privacy controls, a streamlined browser window that shows you more of the page than any other browser and a number of additional features that work with you to help you get the most out of your time online.

What's new in Firefox 94.0:

With 94, you’ll find a selection of six fun seasonal Colorways (available for a limited time only). Now you can find a color to suit (or lift) your every mood.
Firefox macOS now uses Apple's low power mode for fullscreen video on sites such as YouTube and Twitch. This meaningfully extends battery life in long viewing sessions. Now your kids can find out what the fox says on a loop without you ever missing a beat…
With this release, power users can use about:unloads to release system resources by manually unloading tabs without closing them.
On Windows, there will now be fewer interruptions because Firefox won’t prompt you for updates. Instead, a background agent will download and install updates even if Firefox is closed.
And on Linux, we’ve improved WebGL performance and reduced power consumption for many users.
To better protect all Firefox users against side-channel attacks such as Spectre, we’ve introduced Site Isolation. We’ve got your back...errr...side!
We’re rolling out the Firefox Multi-Account Containers extension with Mozilla VPN integration. This lets you use a different server location for each container.
Firefox no longer warns you by default when you exit the browser or close a window using a menu, button, or three-key command. This should cut back on unwelcome notifications which is always nice--however, if you prefer a bit of notice, you’ll still have full control over the quit/close modal behavior. All warnings can be managed within Firefox Settings. No worries! (More details)
And now, Firefox supports the new Snap Layouts menus when running on Windows 11.

Fixed

We’ve reduced the overhead of using performance.mark() and performance.measure() APIs with a large set of performance entries.
Plus, we’ve modified paint suppression during load to greatly improve warmload performance in Site Isolation mode.
You’ll also notice a small reduction in Javascript memory usage.
With this release, you’ll notice faster Javascript property enumeration as well.
We’ve also implemented better scheduling of garbage collection which has improved some pageload benchmarks.
This release also sees reduced CPU usage during socket polling for HTTPS connections.
Additionally, you’ll notice faster storage initialization.
We’ve also improved cold startup by reducing main thread I/O.
Plus, closing devtools now reclaims more memory than ever before.
And we’ve improved pageload (especially with Site Isolation mode) by setting a higher priority for loading and displaying images.
Various security fixes

Enterprise

Enterprise users now have more control over Firefox deployments with the availability of our MSIX package on Windows platforms.
You’ll also notice various bug fixes and new policies have been implemented in this latest version of Firefox. See more details in the Firefox for Enterprise 94 Release Notes.
