Duplicate Tabs Closer by Peuj

Duplicate Tabs Closer detects and closes duplicate tabs.

* Use the WebExtensions API
* Container Tab is supported.

"On duplicate tab detected" options:

• Close tab automatically: automatically closes the detected duplicate tab.
• Do nothing: monitor tabs and update the badge icon to indicate the number of duplicate tabs detected.

"On remaining tab" options (used with "Close tab automatically):

• Do nothing (default): nothing is done after the duplicate tab is closed.
• Activate: once the duplicate tab is closed, the remaining tab is activated.
• Apply opening tab behavior: once the duplicate tab is closed, depending on the default tab behavior, the remaining tab will be moved to the position of the closed tab and activated if needed.

"Priority" options (used with "Close tab automatically" mode and "Close all duplicate tabs" button):

• Keep older tab (default): Keep the already existing tab.
• Keep newer tab: Keep the newer tab.
• Keep tab with https (default on): Ignore the scheme part during comparison and keep the tab with the https scheme.
• Keep pinned tab (default on): Keep the pinned tab.

"Filters" options:

• Ignore hash part in URL (default off): for instance https://addons.mozilla.org/en-US/firefox/addon/duplicate-tabs-closer/#detail-relnotes and https://addons.mozilla.org/en-US/firefox/addon/duplicate-tabs-closer will be considered as the same URL.
• Ignore search part in URL (default off): for instance https://addons.mozilla.org/en-US/firefox/addon/duplicate-tabs-closer/?src=ss and https://addons.mozilla.org/en-US/firefox/addon/duplicate-tabs-closer will be considered as the same URL.
• Ignore path part in URL (default off): for instance https://addons.mozilla.org/en-US/developers and https://addons.mozilla.org/en-US/firefox/addon/duplicate-tabs-closer will be considered as the same URL.
• Compare with tab title (default off): If the URL doesn't match then compare using the tab title.

"Scope" options:

• Container: only closes/displays duplicate tabs that belong to a same container.
• Active window (default): only closes/displays duplicate tabs that belong to a same window.
• All window: closes/displays duplicate tabs for all windows.

Hotkey:

• Alt+Shift+W to close all duplicate tabs (this could be configured in the options in future version)
