Keep Tab Active is a Firefox extension that makes selected tabs report themselves as visible and focused. It blocks common blur and visibility-change events so sites are less likely to pause media, stop updates, or reduce activity when a tab is inactive.
Keep Tab Active is a Browser DevTools & extensions project. It focuses on keeping websites active when switching away from a browser tab. It is built as a consumer product for firefox users who need background tabs to continue normal activity. It is available for free. It ships for the web and embeddable surfaces.
Behind Keep Tab Active is Patrick Beal, and it first shipped in 2026. Among its 8 catalogued features are tab activation toggle, visibility spoofing, and focus spoofing. The interface is available in 32 languages, including Czech, German, and Greek.
