Firefox 114 download and update



Most Firefox installations will receive the new update automatically, thanks to the built-in updating functionality. The updating does not happen in realtime, and some users may want to speed it up by downloading Firefox manually or by running a manual check for updates.
 
Select Menu > Help > About Firefox to display the installed version. The popup that opens runs a check for updates. Any new version found is either downloaded automatically or on user request at this point.

Here are the official download locations:

• Firefox Stable download
  
• Firefox Beta download
  
• Nightly download
  
• Firefox ESR download
  
• Firefox for Android on Google Play
  

Firefox 114.0 new features and improvements

Secure DNS (DNS over HTTPS) settings in UI
 


Firefox 114 makes it easier to configure DNS over HTTPS in the browser. Mozilla calls it secure DNS, and the new options are found under Settings > Privacy & Security > Enable secure DNS using.

There are four options right now that define whether DNS traffic will be encrypted or not when using the Firefox web browser:

• Default Protection -- Firefox makes the decision using the following logic:
  • Use secure DNS if it is available in the region.
    
  • Use default DNS provider, if there are issues with the secure DNS provider.
    
  • Use a local provider, if possible.
    
  • Turn off secure DNS, if a VPN is used, parental controls are enabled, or Enterprise policies are active.
    
  • Turn off secure DNS "when a network tells Firefox it shouldn't use secure DNS".
    
• Increased Protection -- gives the user control over the feature. The secure DNS provider is selected by the user, but Firefox will fall back to the regular DNS provider if there is a problem with the secure DNS provider.
  
• Mac Protection -- gives the user control, but won't fall back if issues are encountered. Warning is displayed if secure DNS is not available.
  
• Off -- the feature is not enabled.
  

Search improvements
 


A new option to search bookmarks has been added to the Bookmarks menu. To access it, select Menu > Bookmarks > Search Bookmarks. This enables a bookmarks-exclusive search filter in the Firefox address bar.
 
Firefox supported this for a long time with the special character *. All it takes is to type * then Space, followed by the search term to search only in the browser's bookmarks.

Mozilla has also added an option to restrict searches to the local browsing history. This option is available in the History, Library and the Application menu. 

Firefox users may use the special character ^ followed by the Space-key to limit searches in the browser's address bar to the browsing history.
