If for some reason you need to change the User Agent in your browser, then this article is for you.
So, User Agent is such a browser string (application) that serves to identify various parameters - browser name, browser bit depth, browser version, version operating system and other options.
The term is commonly used in networking and Internet technologies for applications that access websites. User Agent is used by browsers, search robots (Yandex, Google and others), as well as various "spiders", Cell phones and other devices.
A typical situation at work - the system administrator has closed access to all browsers except Internet Explorer, but I want to use Chrome or Opera, how to be in this case? Let's deceive system administrator. The secret to bypassing the lock is to change the user agent "a browser.
Method 1.
This method works in most browsers. Let's write the parameter in the browser shortcut:
user-agent
Let's force Opera to impersonate Internet Explorer 9, click right click click on the label - "Property" - "Object" and add the line:
User-agent="Mozilla/5.0 (compatible; MSIE 9.0; Windows NT 6.1; Trident/5.0)"
That is, the full path should be something like this:
"C:Program Files (x86)Operalauncher.exe" --user-agent="Mozilla/5.0 (compatible; MSIE 9.0; Windows NT 6.1; Trident/5.0)"
Now it remains only to click "OK".
Method 2Mozilla Firefox
Open the browser in address bar we type the following:
About:config
Click on the "I promise I'll be careful!" button:
general.useragent.override
And in the value we enter the user agent of any browser, for example ie 9:
Mozilla/5.0 (compatible; MSIE 9.0; Windows NT 6.1; Trident/5.0)
Ready. Now we're masquerading as IE.
Method 3. Extensions
AT modern browsers can be used various extensions. We look in browsers for something like: "Load extensions" and look for extensions such as "User-Agent Switcher", "Custom UserAgent String" and others.
A large number of interesting additions have been implemented that can significantly expand the capabilities of this web browser. So, in this article we will talk about an interesting add-on for hiding information about the browser you use - User Agent Switcher.
Surely you have repeatedly noticed that any site can easily recognize the operating system and browser you are using. Almost any site needs to receive such information in order to ensure the correct display of pages, while other resources, when downloading a file, immediately offer to download the required version of the file.
The need to hide information about the browser used from sites may arise not only to satisfy curiosity, but also for full-fledged web surfing.
For example, some sites still refuse to work properly outside of the Internet Explorer browser. And if for Windows users this, in principle, is not a problem (although I want to use my favorite browser), then Linux users and completely roll around in the span.
You can either immediately go to the installation of User Agent Switcher by clicking on the link at the end of the article, or find the add-on yourself.
To do this, click on the browser menu button and go to the section "Additions" .
In the right upper corner window, write the name of the desired add-on - User Agent Switcher .
The screen will display several search results, but our add-on is listed first on the list. Therefore, to the right of it, immediately click on the button "Install" .
To complete the installation and start using the add-on, the browser will prompt you to restart the browser.
How to use User Agent Switcher?
Using the User Agent Switcher is extremely easy.
By default, the add-on icon does not automatically appear in the upper right corner of the browser, so you will need to add it yourself. To do this, click on the browser menu button and click on the item "Change" .
In the left area of the window, elements hidden from the user's eyes will be displayed. Among them is the User Agent Switcher. Just hold down the icon of the add-on and drag it to the toolbar, where add-on icons are usually located.
To accept the changes, click on the icon with a cross on the current tab.
To change the current browser, click on the add-on icon. The screen will display a list of available browsers and devices. Select the appropriate browser, and then its version, after which the add-on will immediately begin its work.
Let's check the success of our actions by going to the page, where information about the computer, including the browser version, is always located in the left area of the window.
As you can see, even though we are using a browser Mozilla Firefox, the web browser is defined as Internet Explorer, which means that the User Agent Switcher add-on does its job perfectly.
If you need to stop the add-on, i.e. return real information about your browser, click on the add-on icon and from the menu that appears, select "Default User Agent" .
Please note that a special XML file is distributed on the Internet, implemented specifically for the User Agent Switcher add-on, which significantly expands the list of available browsers. We do not link to resources for the reasons that given file is not an official solution from the developer, which means that we cannot guarantee its security.
If you have already acquired a similar file, then click on the add-on icon, and then go to step "User Agent Switcher" - "Options" .
A window with settings will appear on the screen, in which you need to click on the button Import , and then specify the path to the pre-downloaded XML file. After the import procedure, the number of available browsers will expand significantly.
User Agent Switcher is a useful add-on that allows you to hide the real information about the browser you are using.
Probably everyone knows that sites and services collect information about users for their own purposes. User Agent - a string that contains information about the version of the operating system, the browser and its special features, as well as the device from which the user visits the site. Sites collect this information to correctly display the page and its content. In the past, sites were built to suit different browsers, so users changed the User Agent to view the site's pages the way they wanted. Developers often use this tool to check the performance of pages from different devices.
By itself, the information provided by the Browser User Agent is not harmful, however, some sites and services use it to identify users. Therefore, the User Agent interferes with those who work with multi-accounts, social networks and trading services: smm managers, arbitrageurs, arbers, etc. With their help, websites, services and social networks detect the simultaneous operation of several accounts and block the entire network, which leads to loss of money and time. To prevent this from happening, users change the User Agent in browsers and programs that have a built-in browser.
Also, User Agent substitution will help to simply remain anonymous and ensure the security of the computer and the data stored on it, as well as bypass restrictions and visit sites whose content is available only when using a specific platform or device.
However, changing the User Agent has disadvantages: some sites may not display correctly, and services technical support will receive incorrect information about your device and browser, which will make it difficult to resolve the problem. Therefore, do it wisely and do not forget to roll back changes if the situation requires it.

User agent- This is a set of parameters by which the browser, operating system, their versions, language and plugins are determined. Such data is required for the correct display of web pages on various devices and browsers.
After the standardization of the main browsers, User Agent data is no longer required, and is used mainly for debugging sites, collecting statistics and "black" search engine optimization. Also, User Agent data can serve as an additional source of information for intruders. Therefore, to ensure anonymous browsing on the Internet, users change the User Agent value using various plug-ins and programs.
It is important to remember that not all plugins are able to correctly change the user's User Agent. Some plugins make the User Agent data spoof only in the client browser, leaving similar server data unchanged. Users whose User Agent values do not match may be suspicious of the administrations of various banking sites and payment services.
