xtS Amazing Tab Manager

Closes duplicate tabs and blocks unwanted popups. No new permissions, everything stays on your device.

xtS Amazing Duplicate Tab Manager is now xtS Amazing Tab Manager. Same extension, same authors, same care with your privacy: version 2 simply does more. Too many tabs? The same page open three times? Ads opening tabs you never asked for? This extension keeps one tab per page and closes the popups a site opens on its own, quietly, in the background. NEW IN VERSION 2, POPUP GUARD • A site opens a tab you did not ask for and it closes on the spot • You are asked once per site whether to block it, and your answer is remembered • The blocked address is kept in a local history with a reopen link, so nothing is ever lost • You decide what counts: ads from another domain, blank tabs, popup windows, each one a switch • Per site you choose ask, block or allow, straight from the toolbar popup • Off by default, because the choice is yours • Needs no new permissions at all STILL THE BEST AT DUPLICATE TABS • One tab per page, automatically, and it jumps you to the copy you already had open • Google Docs, Sheets, Slides, Drive and Calendar by DOCUMENT, not by URL • Google Calendar: every view of the same calendar counts as one tab, and pages where you are creating or editing an event are never closed • Multiple Google accounts handled properly: the same file under another account is still the same file • Microsoft Office (SharePoint and OneDrive), experimental • Suspended tabs from The Great Suspender, The Marvellous Suspender and forks • Ignore www, http and https, #fragments and ?query strings, globally or per site, with wildcard and regex rules CLOSES CAREFULLY, NEVER RECKLESSLY • Activation threshold, so duplicates are tolerated until you pass a number of tabs you choose • Delay with a re-check before closing, so a wrong click fixes itself • Undo button that also creates a temporary exception • Never closes pinned tabs or tabs playing sound • Startup grace period, so restoring your session does not trigger mass closing • Pause button for when you want duplicates for a while YOUR PRIVACY, UNCHANGED • No new permissions in version 2 • Everything stays on your device: no servers, zero network requests • No ads, no tracking, no analytics, nothing collected • You are in control: every behaviour is a setting, and there is a reset to defaults ALSO • Local history of closed tabs and blocked popups, with reopen, and you choose how long to keep it • Badge counter, statistics, import and export, optional settings sync • Available in English, Português, Español, Français, Italiano and Deutsch Install it, forget it, and enjoy a tidier, lighter browser.
