# Firefox was Reportedly Flagged as ‘Potentially Dangerous Apps' by Microsoft Edge

Microsoft Defender SmartScreen is a technology that is developed into the company’s [Edge browser](https://answers.mindstick.com/qa/95968/how-do-i-repair-a-microsoft-edge-browser-on-a-windows-pc-or-laptop) which examines hidden files which are been [downloaded from the internet](https://answers.mindstick.com/qa/94925/why-won-t-my-android-phone-open-up-some-pdfs-but-will-open-other-pdfs-downloaded-from-the-internet) before they can be executed on a device. While Microsoft’s scanner is normally very operative at observing declarations from the internet, it can sometimes accidentally determine safe programs as unsafe - such a Mozilla’s [Firefox browser](https://answers.mindstick.com/qa/110936/how-to-change-spotify-password-on-android-tablet-firefox-browser).

According to a modern document by Techdows, users have been describing that [Microsoft](https://www.mindstick.com/news/587/microsoft-mobilizing-resources-promoting-due-to-the-covid-19-crisis-in-india) Edge has existed in blocking the famous open-source browser’s installers from the authoritative website. This reportedly happens when transferring installers for the stable, beta, dev, and regular variants of the [web browser](https://www.mindstick.com/blog/301688/best-web-browsers-for-2023).

Users on Reddit determined two different instances of the browser flagging the supposed and open-source spectator as software that must harm their device. Users who tried to download the web browser were recognized with the content “***Firefox installer.exe was blocked because it could harm your device***”.

Still, at the moment of publishing this report, we examined the download on [Microsoft Edge Beta](https://www.mindstick.com/articles/323798/the-best-browser-2020) on Linux decided that it seemed not to flag the Mozilla MSI & EXE installers as malicious software. It resembles that the browser’s exposure engine has subsequently been renewed to stop recognizing Mozilla’s software as possibly malicious software.

While disclosure of Mozilla’s web browser may have just been an unexpected malicious positive, this isn’t the initial time that a business has prevented users from practicing a rival service. It has previously held announced that the Facebook-owned [WhatsApp Messenger](https://www.mindstick.com/news/530/whatsapp-chat-box-will-enhance-the-images-videos-size) continued blocking connections to the [Telegram Messenger](https://answers.mindstick.com/qa/96263/is-telegram-messenger-secure-is-it-more-secure-than-whatsapp) assistance on its Android [application](https://www.mindstick.com/articles/12824/calculator-application-in-android), which was reportedly established in a newer update. Microsoft is additionally to present any report on Edge’s blocking of Firefox, but we will modernize this account once it is published.
