Quote:Mozilla redesigned the add-ons manager of the organization's Firefox web browser in a recent update to the browser.

The update modernized the add-ons manager and replaced the traditional layout with a cards-based layout.

Mozilla did not remove any functionality from the add-ons manager in the process but individual add-on listings used more space than before so that fewer add-ons are displayed on the visible part of the page in the new version.

Firefox users who have a handful of add-ons installed in the browser may not mind, but those who have a dozen or more add-ons installed in the browser might.

The Add-ons Manager comes without options at this point to compact the listing to display more extensions at the same time.

Firefox users may modify the page using CSS, however. A user published a CSS style for the add-ons manager on Reddit recently that makes the listing more compact than before.

Here is a screenshot of how it looks like after the changes are applied to the browser:
