Duplicate Tab Blocker 0.1.0.1-signed.1-signed
Prevent duplicate tabs. Allow only one tab for a url. If you click a link that is already opened in a tab, then existing tab would be focused instead of opening a new tab. This works even across firefox windows.
This add-on has been marked as experimental by its developers
This add-on is not compatible with your version of Firefox because of the following:
About this Add-on
There are certain usecases where it won't work such as:
1. Links being redirected by servers.
2. A url is input into the address bar. So if you type in a url in addressbar, this extension will not check for duplicate. I would love to hear feedback on this about whether this should be implemented or not.
3. Undo close tab
Please do rate the extension if you like it and write to me if you have any suggestions.
