 How to connect to PostgreSQL database using pgAdmin 4? In order to set up a connection to the PostgreSQL database, run pgAdmin 4, for example, from the Start menu. As a result, pgAdmin 4 will start. Then click the menu "Object->Create->Server" or right-click on the item "Servers" and select "Create->Server". The server connection settings window will open. On the General tab, we invent and enter the name of our server in the Name field. On the Connection tab, enter the server IP address, username, password, and if you want, you can check the “Save password?” to save the password and not to enter it every time you connect.

Mozilla Firefox

 Mozilla Firefox


The Mozilla Firefox browser is on the fourth position, it is quite a bit behind the Opera browser, but still lost. It is also used by about 10% of visitors.


Positive sides

Even if you don't install add-ons, Firefox will still be a safe and fast browser. Firefox is very reliable and will rarely "please" you with errors and crashes. As a rule, all bugs (shortcomings) and errors are eliminated with regular updates.

Thanks to its open source code, many add-ons and plugins are available for Firefox. With the help of these add-ons, you can "assemble" your browser, i.e. customize Firefox for you and your needs.

Negative side

Firefox will be difficult for beginners. Most users use no more than 10 - 50% of the browser's functionality. If you do not use web development tools, if you are not afraid of viruses and do not want anything complicated, then install Chrome. The abundance of plug-ins and add-ons in Firefox makes the inexperienced user get lost. Most beginners therefore do not use add-ons, and some of them are extremely important and necessary (IMHO, without Adblock and NoScript it is generally dangerous to surf the Internet).

And some Windows 7 users also encountered the fact that when watching a video or listening to music online, their computer hung tightly (did not react to anything, like a screenshot). And the problem turned out to be in a strange conflict with Flash. And this problem is still not fixed.
