Mozilla has released Version 57.0.4 of the Firefox browser.
Firefox Release
January 4, 2018

Version 57.0.4, first offered to Release channel users on January 4, 2018
Brace yourself for an all-new Firefox. It’s fast. Really fast. It’s over twice as fast as Firefox from 6 months ago, built on a completely overhauled core engine with brand new technology from our advanced research group, and graced with a clean, modern interface. Today is the first of several releases we’re calling Firefox Quantum, all designed to get to the things you love and the stuff you need faster than ever before. Experience the difference on desktops running Windows, macOS, and Linux; on Android, speed improvements are landing as well, and both Android and iOS have a new look and feel. To learn more about Firefox Quantum, visit the Mozilla Blog.

Making Firefox look, feel and perform faster was no small feat. Employees and volunteers from around the world worked in record time to create the best Firefox yet. We'd like to extend a special thank you to all of the new Mozillians who contributed to this release of Firefox!

Mozilla has released Version 58.0 of the Firefox browser.
Firefox Release
January 23, 2018

Version 58.0, first offered to Release channel users on January 23, 2018
With this release, we’re building on the great foundation provided by our all-new Firefox Quantum browser. We're optimizing the performance gains we released in 57 by improving the way we render graphics and cache JavaScript. We also made functional and privacy improvements to Firefox Screenshots. On Firefox for Android, we’ve added support for Progressive Web Apps (PWAs) so you can add websites to your home screen and use them like native apps.

Thank you to all of the new Mozillians who contributed to this release of Firefox!

Hello everyone,
We’re happy to introduce the stable version of Opera 51 today. Our new browser comes with internal and practical improvements to help you browse faster and more smoothly.
Some further new features and adjustments include scrolling to the top of a web page with just a click of the tab and an import bookmarks button added to the bookmarks manager. We are also introducing improvements to video pop-out and tabs, a redesigned private mode and more.
Opera 51 improves browsing speed
We are continuing to make Opera faster. In Opera 51, which is now compiled with Clang(Windows), you will see performance gains on benchmark tests such as the new Speedometer 2.0. We challenged Opera 51 (running on HP Spectre with Windows 10) to a speed test against the latest Mozilla Firefox 58. The result: Opera is 38% better than Firefox.
Opera-is-Faster2_min-700x350.png

Click the tab to scroll
Some sites lead us through an endless pit of web content such as our Facebook or Twitter feeds or a busy discussion board on Reddit. These kind of pages leave us with a long climb back to the top! It’s then another long descent down to continue where we were.
Stable51_Scrolltop.gif

We’ve added a new trick to help you quickly scroll up and down a web page. When you need to scroll to the top of a web page, simply click the page’s tab and the page will jump up to the beginning. Clicking the tab again will bring you back to where you were before, so you can continue reading or exploring content.
Import bookmarks added in bookmarks manager
In the bookmarks manager, we’ve added an import bookmarks button together with export bookmarks, available in the expandable menu. This is another way for you to import your bookmarks from other web browsers. You can also import bookmarks and other settings through the Easy Setup menu found in the start page.
Stable51_Import_bookmarks-700x438.png

Collapsible lists of opened and closed tabs in tabs menu
Users who have heaps of tabs opened – rejoice! Today’s Opera 51 release now has two collapsible lists for your open and recently closed tabs. You will find these lists in your tabs bar situated to the far right side of tabs bar.
This will declutter the right side of the browser after opening the tabs menu while also making it easier for you to locate a particular tab.
Stable51_CollapsibleLists-700x438.png

Another new feature for your tabs is to permanently keep tabs pinned no matter what restart option you have selected (open the start page, continue where I left off or open a specific page or set of pages). Your pinned tabs will be restored after opening the browser for a new session.
Private mode style updated
We’ve updated the style of private mode on macOS to match the Windows design while also changing the static image to a new animation across all platforms.
If you frequently use private browsing and wish to bypass the new animation and jump right to your Speed Dial, you can use the “Do not show again” checkbox at the bottom of the page.
Beta51_PrivteMode-.gif

“Back to tab” button for video pop-out
With video pop-out you have possibility to browse the Internet while your favorite video plays in an adjustable window on top. Now, with the “Back to tab” link you have ability to go back to the tab playing the video. You can find it on the top of the popped out video by hovering your mouse over the title of the video.
Beta51_VideoPopOut-700x438.png

Your video will continue playing in the pop-out window after clicking “Back to tab.”
We also updated style of the video pop-out button on macOS.
Allow all sites to use Flash
It’s now possible to change the settings to run Adobe Flash on all sites without the site requesting to do so. By default, Opera requires sites to ask first before allowing sites to run Flash.
You can enable running Flash on all sites without prior request in Settings (Preferences on macOS) > Websites > Flash.
Safely and easily reset browser settings
Resetting your Opera browser can help speed up your future browsing. Overtime, a backlog of cached pages, cookies and unused extensions can all slow down your browser’s performance. Resetting browser settings cleans all that up for you without deleting your bookmarks, history or saved passwords.
Previously, resetting your Opera browser settings to its original state required a lengthy process of deleting the browser after saving preferences in a separate file. Opera 51 stable offers a single button to reset your browser settings in just one click.
You can reset your browser to its original settings in Settings (Preferences on macOS) > Browser > “Reset browser settings…” button.
Stable51_ResetBrowserSettings-700x438.png

Resetting your browser will revert any custom search engines to the default ones, remove pinned tabs, disable extensions and will clear temporary data such as cookies. Your bookmarks, history and saved passwords will remain in place with the refreshed browser.
Preferences backup
We now have a mechanism for backing up and restoring working profile preferences to help avoid the unintentional alterations or corruption of these settings. Whenever profile settings have been read successfully, we create a backup of the files involved. In case the latest configuration cannot be loaded, Opera will use backup instead.
Desktop wallpaper in Opera
Your favorite desktop wallpaper is now available in Opera!
Setting your desktop background as Opera’s wallpaper is as easy as adding your own theme from your system’s library. Head to the Easy Setup menu from the start page and click the wallpaper option with the blue “Desktop” label across it.
Beta51_Desktop_Wallpaper-700x438.png

Under the hood
Opera 51 is powered by a fine-tuned version of Chromium 64. To learn more about the changes in the engine itself, visit dev.opera.com.

If you’re a regular reader of Firefox release notes (and thank you if you are!) you’re probably aware of just how much we’ve invested in the performance of Firefox Quantum.
