Some PDF forms use JavaScript for validation and other interactive features. * Print updates: Margin units are now localized. * Smooth pinch-zooming using a touchpad is now supported on Linux * To protect against cross-site privacy leaks, Firefox now isolates window.name data to the website that created it. Learn more # Fixed * Screen readers no longer incorrectly read content that websites have visually hidden, as in the case of articles in the Google Help panel. * Various security fixes. # Changed * Firefox will not prompt for access to your microphone or camera if you've already granted access to the same device on the same site in the same tab within the past 50 seconds. This new grace period reduces the number of times you're prompted to grant device access. * The 'Take a Screenshot' feature was removed from the Page Actions menu in the url bar. To take a screenshot, right-click to open the context menu. You can also add a screenshots shortcut directly to your toolbar via the Customize menu. Open the Firefox menu and select Customize... * FTP support has been disabled, and its full removal is planned for an upcoming release. Addressing this security risk reduces the likelihood of an attack while also removing support for a non-encrypted protocol. # Enterprise * Various bug fixes and new policies have been implemented in the latest version of Firefox. You can see more details in the Firefox for Enterprise 88 Release Notes. # Developer * Developer Information * Introduced a new toggle button in the Network panel for switching between JSON formatted HTTP response and raw data (as received over the wire). enter image description here Get the most recent version Download Firefox -- English (US) * Windows 64-bit * Windows 64-bit MSI * Windows ARM64/AArch64 * Windows 32-bit * Windows 32-bit MSI * macOS * Linux 64-bit * Linux 32-bit * Android * iOS Your system may not meet the requirements for Firefox, but you can try one of these versions: Download Firefox -- English (US) * Windows 64-bit * Windows 64-bit MSI * Windows ARM64/AArch64 * Windows 32-bit * Windows 32-bit MSI * macOS * Linux 64-bit * Linux 32-bit * Android * iOS * Download Firefox * Download Firefox * Download Firefox * Download Firefox * Download Firefox * Download Firefox * Download Firefox * Download Firefox * Firefox for Android * Firefox for iOS Firefox Privacy Notice All Firefox downloads Need help or want to leave feedback?
