Open links quietly ద్వారా martin

This extension allows you to open links, bookmarks and bookmark folders in muted tabs, from the right-click context menu.

It adds a button on the tab bar that turns on/off the "Quiet Mode".
When Quiet Mode is ON all new tabs are automatically muted.

This add-on needs the permission to read your bookmarks. If you're worried about that, just read the source code. It will take you less than a minute.
