User reviews

Users appreciate Emsisoft Browser Security for its effective malware blocking, strong privacy stance, and overall reliability. However, multiple users note it can slow down browsing speed and sometimes interfere with page loading. The closure of official support forums has made reporting issues more difficult, but the product remains recommended for enhancing browser security beyond default solutions.
Pros

  • Does not collect or sell user data to third parties, ensuring privacy.
  • Helps detect and prevent various malware such as viruses and trojans better than some default protection.
  • Reliable and generally responsive support from developers or company when needed.
Cons
  • Slows down website loading speeds in the browser after recent updates.
  • Can prevent some pages in Firefox from loading properly, causing usability issues.
  • Lack of quick and easy ways to report problems due to closed forums or support channels.

Очень хорошее и полезное расширение, которое не раз меня выручало. Блочит всякие вирусные говносайты, плюс ко всему не собирает и не продаёт ваши данные третьим лицам, в отличии от других расширений. Огромное спасибо разработчикам! Обновляйте почаще.
