1stbrowser Removal Instructions (Uninstall 1stbrowser)

1stbrowser is a web browser that is promoted on its official page as “the first fully customizable browser” with a variety of icons and designs that you can choose from. It is also supposed to provide you with quick access to your favorite websites.

These may seem like useful features, however, the browser is classified as a potentially unwanted program for a reason. Although it can be downloaded from its official site, it also gets distributed bundled with freeware. Moreover, the application is also known to have adware capabilities. We suggest that you delete 1stbrowser from your PC and go back to using a more reliable web browser as soon as you can.

1stbrowser-How does 1stbrowser work?

1stbrowser is based on the Chromium engine, which makes it look rather similar to Google Chrome. However, you should know that the application is not related to Google Inc. in any way. It was developed by SIEN S.A., which is a company that is also responsible for an ad-supported program called Iminent. Once 1stbrowser gets installed, it will be set as your default web browser automatically. Soon after this happens, you will start noticing that the amount of commercial data that appears on your screen while you surf the Web has considerably increased. We urge you not to click on any of the ads, because they may be unreliable. If you do not want to risk your computer’s safety, you should terminate 1stbrowser without delay.

Another aspect of the application that you should know about is that it tracks your cookies. This means that the browser collects information about what pages you visit, what ads you click on, what you search for online, and so on. The collected information is used marketing purposes and may be sold to third parties. Although this data is not personally-identifiable, you should still be careful with the sources that you choose to share it with.
