BHO

BHO is an acronym that can refer to multiple terms depending on the context. In computing, a Browser Helper Object (BHO) is a software component designed for Internet Explorer to extend the browser’s functionality. BHOs run inside the browser process and can interact with web pages, modify content, or provide additional features such as toolbars or integrated search. Because BHOs have broad access to system resources, they have been a frequent focus of security concerns, and management of BHOs often involves security settings and, in enterprise environments, application whitelisting. With the decline of Internet Explorer and the rise of alternative extension models in other browsers, the practical use and relevance of BHOs have diminished in modern consumer environments.

In another domain, butane hash oil, abbreviated BHO, refers to a cannabis concentrate produced by extracting cannabinoids with liquid butane. The resulting product is typically a viscous oil or wax with high potency. Production involves flammable solvents and carries safety risks, including fire or explosion hazards if not handled properly. Legal status and regulations surrounding production, possession, and distribution of BHO vary by jurisdiction, and many areas regulate or prohibit its manufacture or sale. Public health and safety discussions commonly emphasize the potential for residual solvents and the importance of legal compliance.

Other uses and meanings of the acronym BHO exist in specialized fields and organizations. Due to its multiple meanings, context is important for interpretation.
