Online Programs

With the development of the Internet, cloud services and various online software are becoming more widespread. Some of the services are paid, but mostly services at such sites are provided for free. In my daily work I myself use a few about a dozen of these services.

Often, in terms of quality of work, they are not inferior to similar software installed on the computer. And since the Internet is firmly entrenched in everyday life and in the minds – the sooner the more programs were installed on a PC, the more it could do. Today, a suddenly broken Internet makes a PC virtually useless. The sense of installing unnecessary software in the system is less and less, and using online more and more. Today, most programs replace bookmarks in an Internet browser. Continue reading

Mozilla Firefox Web Browser Overview

For more than 10 years I have been using the “Firefox” browser in my daily work on my PC and have gained a decent experience, which I hasten to share. This article is an introductory FAQ for beginners, which reveals and demonstrates the main features of the browser. This article is also a guide to setting up Firefox for beginners. So to say, “read before use.”

Most users simply install the browser and use it as is. Naked Firefox loses to WebKit browsers in a number of ways. At the same time, if we try to dress up (set up) the browser at least a little, then WebKit browsers (Chrome, Opera, etc.) will start to play strongly, and Firefox – vice versa. After all, with the help of extensions, this wonderful browser can be turned into an ultra-convenient assistant that can make work on the Internet many times more convenient.

Since Firefox can be configured for very different tasks, this review contains general (basic) setup instructions that Continue reading
