First of all, if you want to use the Internet anonymously and safely, then you should clear the cookies, cache and the history of your visit. Let’s start with this.
In the upper left corner press on the Opera icon, put your mouse over the “History” field and the other field will appear. Press the “Clear browsing data” button.
Click on the “Advanced” cleaning. Tick all the checkboxes and do not forget to choose from the “Time range” drop-down box -> “All time”. And press the “Clear data” button.
Press the Opera icon once again, and from the drop-down menu press the “Options” button.
In the upper right corner, you can see the search field. Let’s use it to make the search even easier. Just type “Proxy” in it.
After this, press the button on the right side of the “Open your computer’s proxy settings” field.
In the newly opened window put a tick for “Manual proxy setup” -> “Use a proxy server”
Fill the fields with the purchased proxy server data. The IP address and port. We will take one from our proxy servers. And then press the “Save” button.
Search anything in Opera and the authorization window will appear if you haven’t purchased the proxy with IP authentication. If you have purchased proxy with login and password authentication, then enter your username and password.
The configuration is done correctly. The browser will start using the proxy since this moment.
An active proxy server in Opera can often cause problems connecting to certain sites and other similar functions. In this case, it is better to disable it. The browser uses proxies to send indirect requests to network services, which allows you to visit resources without being noticed. And since the browser proxy is used only by the user's decision, canceling the command will require a manual shutdown.
Only after deleting all the data you can proceed to the proxy shutdown.
Important note: restart the browser after such actions, to save all changes. Data in the “Proxy server” might be filled, you shouldn’t delete it.
Proxies in Opera are quite simple and convenient in daily use, so disabling them is advisable only in critical cases.
Also, read the instructions on how to connect the proxy on the Google Chrome browser.
