Browser Guard

Tab cleanup, clean search, web capture, local screen recording, dark mode, media saving, audio boost, and focus blocking for Chrome.

Browser Guard keeps Chrome calmer when your tab strip gets crowded. It combines the browser tools I kept installing separate extensions for: duplicate tab cleanup, tab organization, clean search, full-page capture, local screen recording, dark mode, media saving, audio boost, and focus blocking. Main features: • Prevent duplicate tabs and focus the existing tab when possible. • Keep single-page app routes distinct, including AWS console pages. • Sort, group, and merge browser tabs across windows. • Replace the new-tab page with a clean workspace and tab list. • Capture full-page scrolling screenshots as PNG files. • Record a selected screen, window, or tab as a local video file. • Force dark mode on websites with brightness, contrast, sepia, and excluded-site controls. • Save direct video/audio files from supported pages. • Show an in-page video download overlay with X/Twitter quality options when available. • Boost active-tab volume up to 600% and add bass boost. • Block distracting sites during work hours, after daily limits, or with a timed Nuclear Option. • Resume blocked tabs automatically when the timer or schedule ends. Browser Guard is local-first. It does not run a backend service, does not sell data, and does not upload your screenshots, recordings, tabs, or browsing activity.
