- Can/Should i trust this addon? You can view the source code by either visiting the Homepage/Support Site or just saving/downloading the XPI (which is really just a ZIP Archive) and then extract it locally. The Sources in the XPI should be unofuscated and unminified (HTML,CSS and JS), so it's as easy to read as possible. Alternatives you can also use the CRX Viewer Extension by Rob W to inspect the XPI sources. If you have an questions, you can also open an issue on the support site and i'll try and answer to the best of my abilities. If you are no programmer and are still feeling unsure, you might want to visit one of the official or unoffical mozilla communities and ask if someone there with more knowlege can take a look.

- Permissions: This add-on tries to use the minimal number of required permissions to successfully fullfill its intended purpose. If you think this could be improved please let me know by opening an issue and i will try to look into it. See more

Functional extension with many extra options. It checks the container of each tab, so there's no risk of closing tabs with the same URL, but with different credentials (be careful, though, that if a site manages states using cookies, local storage or anything else that doesn't change the URL, the extension will consider the tabs as duplicates and close them.) It indicates how many duplicate tabs are there in a window. It has an option to keep the oldest tab, instead of the newest. If offers three optional hotkeys to remove duplicate tabs.
