What's new in Firefox

Version 83.0:
New:
  • Firefox keeps getting faster as a result of significant updates to SpiderMonkey, our JavaScript engine, you will now experience improved page load performance by up to 15%, page responsiveness by up to 12%, and reduced memory usage by up to 8%. We have replaced part of the JavaScript engine that helps to compile and display websites for you, improving security and maintainability of the engine at the same time.
  • Firefox introduces HTTPS-Only Mode. When enabled, this new mode ensures that every connection Firefox makes to the web is secure and alerts you when a secure connection is not available. You can enable it in Firefox Preferences.
  • Pinch zooming will now be supported for our users with Windows touchscreen devices and touchpads on Mac devices. Firefox users may now use pinch to zoom on touch-capable devices to zoom in and out of webpages.
  • Picture-in-Picture now supports keyboard shortcuts for fast forwarding and rewinding videos: use the arrow keys to move forward and back 15 seconds, along with volume controls. For a list of supported commands see Support Mozilla
  • When you are presenting your screen on a video conference in Firefox, you will see our improved user interface that makes it clearer which devices or displays are being shared.
  • We’ve improved functionality and design for a number of Firefox search features:
    • Selecting a search engine at the bottom of the search panel now enters search mode for that engine, allowing you to see suggestions (if available) for your search terms. The old behavior (immediately performing a search) is available with a shift-click.
    • When Firefox autocompletes the URL of one of your search engines, you can now search with that engine directly in the address bar by selecting the shortcut in the address bar results.
    • We’ve added buttons at the bottom of the search panel to allow you to search your bookmarks, open tabs, and history.
  • Firefox supports AcroForm, which will allow you to fill in, print, and save supported PDF forms and the PDF viewer also has a new fresh look.
  • Our users in India on the English build of Firefox will now see Pocket recommendations in their new tab featuring some of the best stories on the web. If you don’t see them, you can turn on Pocket articles in your new tab by following these steps.
  • For the recently released Apple devices built with Apple Silicon CPUs, you can use Firefox 83 and future releases without any change. This release (83) will support emulation under Apple’s Rosetta 2 that ships with macOS Big Sur. We are working toward Firefox being natively-compiled for these CPUs in a future release.
  • This is a major release for WebRender as we roll out to more Firefox users on Windows 7 and 8 as well as on macOS 10.12 to 10.15.
Fixed:
  • This release also includes a number of accessibility fixes:
    • Screen reader features which report paragraphs now correctly report paragraphs instead of lines in Google Docs
    • When reading by word using a screen reader, words are now correctly reported when there is punctuation nearby
    • The arrow keys now work correctly after tabbing in the picture-in-picture window
  • For users on macOS restoring a session with minimized windows, Firefox now uses much less power and you should see much longer battery life.
  • Various security fixes.

Excellent browser and love all it's features; yes I have used others; Vivaldi, Safari, Chrome, Opera; all have something to offer, but Firefox hit me with a brick, after I learned how to sync my account, so I will lose nothing. The 'Generic forks; Cliqz, Waterfox, Pale Moon and others do not present the needed security updates and new versions as quick as Firefox. Firefox is at 73.01, and is rock solid. I do not have a cell phone, so my data is synced with Firefox. I read the complaints by choice, reviews; that will not stand in my way. If you are not a fan of FF, please use another browser that floats your boat; that is using a "moral compass"

Firefox 83.0 appears to be causing conflicts with Instagram on macOS Big Sur. Since 83.0 update, if you click an IG link, you are directed to the IG log-in page, not the actual linked page. If you paste an IG user account address directly into the browser, Firefox again re-directs you to the IG log-in page.

I find Firefox simple and fast. Provides comfort and security on the net. Blocks all non essentials from the net.

Hey all, was wondering if someone could help me here. I'm having a strange issue with Firefox and Big Sur. When I launch Firefox, and I have notifications from Youtube waiting, it will show duplicates. I have only noticed this as of FF 83. 82.0.3 didn't have this behavior, and none of my other notifications act strange in Big Sur, in fact, the upgrade has been extremely solid and smooth for me with mainly cosmetic glitches from time to time. I am trying to find out if this is a Big Sur bug, a Firefox bug, or a Youtube bug. The latest chrome under Big sur also shows YT notifications correctly. The funny part is, it's only when I first start FF, this happens. If it's running and I get a YT notification about a video, etc, I see it once as expected. I've cleared all of YouTube's site data from fF, disabled notifications fir FF and YT and re enabled each, and even restarted. If anyone else has experienced this please let me know especially if you were able to resolve this. Thanks

This version is incredibly fast! As much for launching the application as for loading web pages. In addition, there are a ton of additions to customize the browser.
