关于此扩展
Too many tabs slowing your browser to a crawl? Every open tab quietly eats memory — even the ones you haven't touched in hours. Dozr fixes that.
Dozr automatically suspends inactive tabs to free up RAM, so your browser stays fast and your laptop stops overheating. Suspended tabs stay right where they are in your tab bar and reload instantly when you click them — you lose nothing.
WHAT DOZR DOES
• Auto-suspends tabs after they've been idle for a time you choose
• Frees the memory those background tabs were wasting
• Shows your tabs in four clear views: Active, Inactive, Suspended and Sessions
• Estimates how much memory each tab is using, so you can spot the heavy ones
• One click to suspend all inactive tabs — or wake any tab back up
• Global search across every tab and saved session, so you find anything instantly
SAVED SESSIONS
• Save your open tabs as a named session, then close them without losing anything
• Restore a whole session in a new window whenever you need it
• Pick exactly what to save: whole groups of tabs, or individual ones
• Sessions are stored on your device only — never uploaded anywhere
YOU'RE IN CONTROL
• Never suspends the tab you're using
• Keeps pinned tabs awake
• Keeps tabs playing audio or video awake (no interrupted music or calls)
• Allowlist any site that should never sleep (e.g. your AI chat or email)
• Set your own idle time and check interval
PRIVATE BY DESIGN
• No accounts, no tracking, no ads
• Dozr does not collect, store, or send any of your data
• Everything runs locally in your browser
PERFECT FOR
• People who live with 20, 50 or 100+ tabs open
• Heavy users of AI chats, online documents, design tools and other memory-hungry sites
• Laptops with 8 GB of RAM that need every megabyte back
Available in English, Spanish and Portuguese.
Note: exact per-tab memory isn't exposed to extensions by the browser, so the figures shown are estimates based on documented averages. For precise numbers, the browser's own Task Manager (Shift+Esc) is one click away.
Install Dozr, keep the tabs you love, and let the rest take a nap.
