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 tab management, workspace recovery, clean search, screenshots, local screen recording, media tools, dark mode, audio controls, and focus blocking in one local-first extension. Main features: • Prevent duplicate tabs and focus the existing tab when possible. • Keep single-page app routes distinct, including AWS Console pages. • Sort, group, organize, and merge tabs across windows. • Search open tabs, saved workspaces, and snoozed tabs from one Command Center. • Save and restore tab workspaces. • Automatically create recovery snapshots before major tab changes. • Undo cleanup actions and restore previous tab layouts. • Snooze tabs and reopen them automatically later. • Release memory from idle tabs while protecting active, pinned, audible, excluded, and edited-form pages. • Replace the new-tab page with a clean search workspace and tab list. • Capture full-page scrolling screenshots, including horizontally overflowing pages. • Crop and annotate screenshots with pen, arrow, rectangle, blur, and text tools. • Copy edited screenshots or save them as PNG files. • Record a selected screen, window, tab, or selected area as a local video file. • Control recording resolution, frame rate, video bitrate, and audio quality. • Force dark mode on websites with brightness, contrast, sepia, and excluded-site controls. • Save direct video and audio files from supported pages. • Optionally show in-page video download controls with quality choices on X/Twitter, Facebook videos and Reels, and TikTok. • Boost active-tab volume up to 600% and add up to 24 dB of bass boost. • Block distracting sites using schedules, daily limits, strict mode, or a timed Nuclear Option. • Save reusable focus profiles and review seven-day focus insights. • Resume blocked tabs automatically when a timer or schedule ends. • Export local data as JSON or workspace links as Markdown, then restore from a backup when needed. Browser Guard is local-first. It does not operate a backend service, sell personal data, or upload your screenshots, recordings, tabs, or browsing activity. Screenshots, recordings, settings, workspaces, recovery data, and focus information remain on your device.
