Download Mozilla Firefox 109.0 With Unified Extensions Button

Mozilla Firefox version 109.0 is now available for download. This is the first release of the year 2023 but does not include any significant new features or changes.

If you have already Firefox installed on your computer, then you may not be able to update it using the update function immediately, since Mozilla will be rolling that out gradually. However, you can still upgrade to it by downloading version 109 from the links provided below.

Mozilla still hasn’t published the release notes for this update, but you can find them here once they are available. But we can see a few differences just by using Firefox version 109, which have been discussed below.

If you are a developer, you may want to check out Firefox 109 release notes for developers.

Let us take a closer look at what this release offers before getting to the downloads.

New in Firefox 109

This release includes the following updates that are currently known:

• Unified Extensions Button

  If you use more than one extension for Firefox, you will notice that you now see only a single expandable button for them in the toolbar. This gives a neat and tidy look to the toolbar.

  Simply click on the button to manage all your active extensions.

  

• Firefox supports web extensions that use Manifest Version 3.

  These Manifest APIs control how Chrome extensions communicate with the browser. Google will implement Manifest V3 as an application programming interface (API) in Google Chrome.

• Updates for developers

  The following list of updates is included in Firefox 109:

  • The HTML “range” element now supports a list attribute that can link to a “datalist” element to allow Firefox to display tick marks along the range.
  • The CSS “content-visibility” property now supports the value “auto” that will allow content to skip rendering if it is not relevant to the user.
  • Firefox now supports “scrollend” events for when a user has completed scrolling.
  • Manifest V3 is now supported for Firefox add-on developers by default while Manifest Version 2 continues to be supported. The default Content Security Policy for Manifest V3 extensions has also been updated.
