Firefox now offers a free
built-in VPN. Whether you’re using public Wi-Fi
while traveling, searching for sensitive health information, or shopping for
something personal, this feature gives you a simple way to stay protected.
Once you sign in and turn it on, you can hide your location and IP address by
routing it through a secure proxy while you browse in Firefox. You will get
50 GB of protection every month, with the option to turn it on or off for
specific websites. This feature is progressively rolling out in the US, UK,
Germany and France starting today.

https://i.meee.com.tw/uE9CCPn.png
Many PDF files will now load significantly faster thanks to hardware
acceleration.
Firefox now automatically blocks notifications and permanently revokes
permissions for any website flagged as malicious by SafeBrowsing. This
prevents unsafe sites from sending background notifications to users,
commonly used for ads, spam or phishing.
You can now add a Share button to your toolbar via
Customize Toolbar,
making it easy to share the current tab using your Windows or macOS system
sharing options.
https://support.mozilla.org/kb/customize-firefox-controls-buttons-and-toolbars
Address Autofill is enabled for users in Australia, India, Italy, Poland
and Austria.
https://support.mozilla.org/kb/automatically-fill-your-address-web-forms
Explore more of the web with new on-device
translation support for Bosnian,
Norwegian Bokmål, Serbian and Thai — plus improved accuracy for Croatian.
https://support.mozilla.org/kb/website-translation
Firefox Labs︰
Tab notes feature that lets you attach a short note to a web page is now
available in Firefox Labs. You can use notes to remember why you opened a
page, what you planned to do next or any details you want to revisit later.
Please give notes a try and share
your feedback on what works well and what
can be improved.

Fixed︰
Increased robustness of HTTP/3 upload performance for unstable network
conditions.
Various
security fixes.
https://www.mozilla.org/security/advisories/mfsa2026-20/
Changed︰
The TrustPanel combines the privacy and security panels accessed from the
address bar to give the user one place to check the Privacy and Security
settings of the current page. Learn more.

Security has been strengthened by tightening the requirements for
JavaScript files that can be loaded in the parent process, providing additional
defense in depth against potential threats.
On Linux, Firefox will now default to the XDG portal file picker if
available, rather than the GTK3 one, which is usually better integrated with
the user's desktop environment, and more powerful.
Firefox error pages have a fresh new look, with updated visuals that better
match the overall feel of Firefox. The redesigned pages create a more
cohesive experience while making it clearer what went wrong.
https://i.meee.com.tw/N2wqaV3.png
On Windows, Firefox will use the modern
Windows.Devices.Geolocation API for
geolocation instead of Windows 7 location API.
Developer︰
Developer Information

The toolbar of the Storage Inspector now has a button to delete all entries
of the currently selected storage.
Besides each CSS declaration related to a computed value shown in the
Computed view there's now an icon to jump to it in the
Rules view.
https://mzl.la/4bHrxjB
Web Platform︰
showPicker() now supports text-based
<input> elements with an associated
<datalist>, displaying the autofill dropdown. See documentation.
https://mzl.la/40QJzuW
The functions
xywh() and
rect() were previously implemented for the
clip-path and
offset-path properties. They are now also available for the
shape-outside property.
https://mzl.la/4butIrV
https://mzl.la/4spBMAh
https://mzl.la/4svwPWv
The
math value of the CSS font-family is now supported and used by default
for MathML's
<math> element. It enables Web developers to indicate special
fonts with advanced math features should be used. Firefox will rely on the
serif font for mathematics defined in Firefox preferences.
https://mzl.la/4rQnjfC
https://developer.mozilla.org/en-US/docs/Web/MathML/Reference/Element/math
Added support for the HTML attribute
popover="hint".
https://mzl.la/3PlbYqv
Enabled
media element pseudo-classes, such as
:playing,
:paused…
https://bugzilla.mozilla.org/show_bug.cgi?id=2013367#c0
Enabled the spec-compliant
HTMLMediaElement.captureStream() API.
https://bit.ly/3PkGDnT
Added support for closing popovers & dialogs with the Android Back Button,
and implemented the
CloseWatcher API for handling this in script.
https://developer.mozilla.org/docs/Web/API/CloseWatcher
The new
Reporting API provides a generic reporting mechanism for web
applications to use to make reports available based on various platform
features (for example Content Security Policy, Permissions-Policy or feature
deprecation reports) in a consistent manner.
