Mozilla decided to keep Compact Density in Firefox, but hide it by default

The team behind the Firefox browser has changed their plans on Compact Density removal from customization options. The browser will continue to include Compact Mode, but it will be hidden by default, and tagged as "not supported" when you enable the option.

For Firefox 89, the Compact density option will be hidden by default in Menu > Customize Firefox.

However, there will be a new about:config option to revive the missing option. In order to bring it back, you need to set the browser.compactmode.show value to true. Right after that, if you open the Menu > Customize Firefox tool, you will find the Compact mode available. However, it is tagged as not supported.

Mozilla is not enthusiastic about this mode. According to the company, not that many users use it and find it hard to discover. For this reason, the company decided to remove it from the browser. However, the company eventually changed its mind, and made the Compact option hidden instead. This had happened probably due to negative feedback the company received after announcing the change.

Now, for existing Compact Density users, the option will remain visible. Users who never used the Compact density option won't find it visible, but will be able to activate it.

The Compact UI option allows you to reduce the UI size in favor of web content. Currently, Firefox and Vivaldi are the only browsers that offers customizable UI size. Other popular browsers, such as Chrome or Edge, use fixed UI size that changes depending on the system DPI scale.

    I appreciate that Mozilla respects the feedback, and I take back what I said about the cancelled removal. However, we have to wonder how a supposedly privacy-supporting foundation knows so well how people run its browser (including mere UI settings).

    Calling an existing feature “not supported” also leads to some questions. Will there be changes that will eventually break it? In addition, “not supported” may confuse people and lead them to believe that their Firefox install is buggy. Anyway, it seems to be a petty thing to do.
