Browser-test.info

The Browser-test.info domain is not associated with Web browser vendors despite what its name may suggest. The Browser-test.info domain is flagged by AV developers as unsafe because it poses as an official site by the Mozilla Foundation that is used to deliver an update to your browser. The Browser-test.info domain is not employed by the Mozilla Foundation and the software advertised on your screen should not be installed. Web surfers may navigate to h[tt]ps://browser-test[.]info/browser/firefox/ when they click on advertisements on untrusted pages or have ad-supported add-ons that cause unsolicited browser redirects. The URL h[tt]ps://browser-test[.]info/browser/firefox/ points to a phishing page that produces a pop-up dialog box. The content at h[tt]ps://browser-test[.]info/browser/firefox/ is styled like an update page by the Firefox developers and offers the following text:

'Authentication Required
"CLICK ON CANCEL TO CONTINUE!"
User Name: [text box]
Password: [text box]
Firefox requires a manual update to the current version
[Install now|BUTTON]'

Browser-test.info is used to promote and force users to install a browser add-on with the name '1.1' that is recorded to push advertisements in pop-up windows, cause browser redirects, and inject search-related links on Google, Bing and Yahoo. Clicks on the 'Install now' button and other links at browser-test[.]info/browser/firefox may force your browser to run in full-screen mode. A pop-up for installing a browser add-on is displayed in the top left corner if the browser-test[.]info/browser/firefox page is loaded in full-screen, and you may notice a warning in the top center part of the browser window. The '1.1' add-on from Browser-test.info may decrease the performance of Mozilla Firefox by running a CoinHive crypto miner in the background.

Installing fake updates to your browser can expose you to various attacks like online identity hijacking, crypto jacking, financial fraud and drive-by downloads. It is recommended to avoid the Browser-test.info domain and pages that may require you to install updates to your Web client manually.
