NoStim

Stay focused by blocking distracting sites. No stim lock in.

NoStim is a productivity and privacy extension that helps you stay focused and protect your browser fingerprint. Block distracting websites with a single toggle. When Focus Mode is on, any site on your block list gets replaced with a clean "Stay Focused" page that shows how long you've been locked in. Need a quick break? Hit the 5-minute break button and get right back to work. The Tab Eliminator automatically closes tabs you haven't touched in a set number of days. No more tab hoarding. Pinned tabs and sites you mark as preserved are always safe. You control the idle threshold and can reopen anything that was closed. LinkedIn Shield runs quietly in the background, blocking LinkedIn from scanning your browser to detect which extensions you have installed. It intercepts fingerprinting probes, cleans up DOM artifacts, and blocks tracking endpoints. Your extensions are your business. Everything stays on your device. No accounts, no tracking, no data collection, no servers. Just you and your focus.
