What is Fenix?

Fenix is a web browser developed by Mozilla, the same company that developed Firefox. Fenix is much faster and slimmer compared to Firefox, the user interface has nothing to do with Firefox, it is simpler and goes in the direction of the current trend in simplification of user interfaces. One thing that contrasts with other web browsers is the location of the search bar, it is usually located at the top, but in Fenix, it is located at the bottom of the main window.

One thing to keep in mind, Fenix is still in the development stage, it is not yet officially released. So expect to see a lot of bugs and limitations.

How to use Fenix

The use of Fenix is no different from other web browsers. Just enter the URL of the website you want to visit in the URL bar at the bottom of the main window or use that same bar to search the web using Google or any other search engine (can be defined in the settings).

The website opens in full-screen mode, in which the user can save the page or add it to the bookmark search on the page for a given word or view the page in desktop mode.

Tabs, and how to manage them

Fenix manages tabs differently from Firefox and other web browsers. From the main window, the user can create several tabs as usual, but when the user wants to check all open tabs, he/she will be taken to the main window where the tabs will be displayed as a list. the entries in the list could be grouped into a single tab or dragged left or right to close the tab.

Private browsing

Okay, we all know that a browser without private browsing mode is not a usable browser. therefore, of course, Fenix supports this mode in which no information is saved in the local machine in the private browsing session, which means that no temporary files, history or passwords are saved. The user can access the private browsing mode by clicking on the mask icon on the upper side of the main window.
