Quote:Mozilla plans to roll out a number of changes in Firefox 64 that are extension related. The organization plans to roll out an update to about:addons that changes the design of the page.

The redesign introduces a card-based interface but does not remove or change functionality on the page.  The one downside to the new interface is that it requires more space to display the same information on the screen.

Firefox users who experience display issues can zoom in or out of the page to display all options and information at once.

Another extension-related change that Mozilla plans to introduce in Firefox 64 is the ability to remove any extension directly.

Remove Extensions

Just right-click on any extension icon displayed in the Firefox interface and select the new "Remove Extension" option to start the process.

Firefox displays a prompt when you select the uninstallation option from the context menu to verify that this is the desired action.
