Anti-Tab-Flood

Detects duplicate tabs and closes either the new one or the old one, depending on your settings.

No more duplicate tabs: Anti-Tab-Flood closes them automatically, right when you open them. Clicked a link to a page that is already open? The extension takes you to the existing tab and closes the duplicate. Rather keep the new tab? One setting does it. HIGHLIGHTS • Automatic: the duplicate is closed as soon as you navigate (new tab, typed address, bookmark, link click), with nothing to do. • Follows redirects: SSO sign-in, apps like Jira… the duplicate is recognised even when the page goes through several addresses before landing. • Ignores tracking parameters: a newsletter link (…?utm_source=…) is recognised as the page already open, without mixing up two different YouTube videos. • Undoable: a “Reopen” notification brings a closed tab back, in its place. • Careful: pinned tabs are protected, you choose excluded sites, and the extension never acts on a reload, on Back / Forward or on “Duplicate tab”. • Private: no data ever leaves your browser. No account, no server, no analytics. SETTINGS Essential: • Keep the tab already open, or the new tab • Compare the full address, the address without tracking parameters, or only the site and path • Excluded sites, with a popup button to exclude the current site in one click • “Close open duplicates” button to clean up in one go Advanced: • Look for duplicates in all windows or only the current window • Protect pinned tabs and tab groups • Ignore the anchor (#…), editable list of tracking parameters • Turn the “Reopen” notification on or off Interface in French and English.
