August 19, 20251 yr Today, Mozilla has published the final builds of the Firefox 157 open-source web browser ahead of its official unveiling on September 29th, 2026, so it’s time to take a look at the new features and improvements.Highlights of Firefox 157 include the brand-new design that we previewed in Firefox Nightly back in July. The new theme is called Nova and promises to make the popular open-source web browser feel cleaner, faster, adaptable, and warmer, according to Mozilla.As part of the new Nova design, Mozilla is also bringing back the Compact mode with reduced spacing for smaller screens, alongside a Standard mode providing balanced spacing for most screens and a Touch mode optimized for touch screens with larger window elements and click targets.Firefox 157 also improves support for displaying HDR videos encoded in 8-bit color formats as HDR in most cases, which fixes several cases of dull gray-looking videos that should have been more vibrant, and improves audio/video synchronization when changing playback rate on HTMLMediaElement.On top of that, this release improves the Vertical Tabs sidebar to work better when the cursor moves to the edge of the screen in full-screen mode, adds support for viewing recent searches on Android when tapping the search field, and adds support for hardware AV1 decoding to WebRTC video calls.Among other changes, this release also improves address bar searching for the typed text instead of opening the selected suggestion when a page was still loading, such as shortly after Firefox started, removes Amazon as a built-in search engine, and brings localized suggestions in your address bar to more users.In addition, pressing Tab now moves focus straight to the text field of the address bar and search bar instead of stopping on the search engine button first (the button can still be reached with Shift+Tab). Lastly, Firefox 157 fixes an issue on Windows where making a video full-screen would leave the taskbar showing over the video.Last but not least, Firefox 157 shows a warning in the site information panel (the shield icon in the address bar) and in Settings when it has been set up to record its encryption keys, which could let other software on the computer read encrypted web traffic.Also, Firefox 157 fixes an issue with video from phones and tablets appearing sideways or upside down in WebRTC calls, and updates the web page alert(), confirm() and prompt() dialogs, the color and date pickers, and form autocomplete drop-downs to match the page’s light or dark color scheme.For web developers, Firefox 157 introduces support for the at-rule() function for @supports, which allows authors to detect browser support of specific at-rules, such as @supports at-rule(@scope), and support for the chain value for the CSS overscroll-behavior property.Silent installationArabicAIO Silenthttps://www.mediafire.com/file/fmgmgat1dmfg8tr/Mozilla+Firefox+157.0+Ar.7z/filehttps://transfer.it/t/YOqcoogDmZwKEnglishAIO Silenthttps://www.mediafire.com/file/bct2x8bbqc7w4lc/Mozilla+Firefox+157.0+En.7z/filehttps://transfer.it/t/pTkjRpwTkL6Z FrenchAIO Silent https://www.mediafire.com/file/hai7agwnj3mcj66/Mozilla+Firefox+157.0+Fr.7z/filehttps://transfer.it/t/OoWxN0wTwTCbMozilla Firefox 115.0.3 (Last version support Windows 7)ArabicAIO Silenthttps://www.mediafire.com/file/4aov9jd1s57cskj/Mozilla.Firefox.115.0.3.ar.AIO.Install.Silent.7z/fileEnglishAIO Silenthttps://www.mediafire.com/file/jzjws6mtjkw4yvh/Mozilla.Firefox.115.0.3.en.AIO.Install.Silent.7z/file Edited 1 hour ago1 hr by T3rM1nat0Rr3
