Built on the Internet Explorer browser engine, Browzar is a browser application marketed as a new apex of intimacy. However, several features integrated in the Internet Explorer shell application have backlashed generating an increasing volume of criticism. Ajaz Ahmed - founder of Freeserve and Browzar- has been on the defensive ever since and recently announced that Browzar will be revamped in response to the negative feedback. Ahmed also defended the application arguing that Browzar is in Beta phase and that all issues will be remedied prior to the official launch.

The most controversial issues with Browzar spawned in relation to the IE shell application's default homepage and the use of Yahoo's Overture search engine. Overture makes no distinction between sponsored results and the general result returned to searches. This aspect determined Browzar to be labeled as adware. Ahmed rejected the criticism but stated that the search engine will be dropped from the application. "We don't do adware. We have Overture and people are not happy with the way that they show their results. As a response to that, the engine is going to be changed," promised Ahmed.

Additionally, Browzar, designed to leave zero navigation fingerprints by dispensing of history files, cookies and the search auto-complete feature, has delivered a performance inferior to its advertising due to the close integration with Internet Explorer. In this context, an update will be released for the IE shell application to address a problem that permits Web pages to be stored in the cache of Internet Explorer.
