Thank you for adapting advanced tab tools to the new version of Firefox. If I may ask for a feature, could you please add an option to lock tabs from closing when double clicking them? I think it would be very useful to lock tabs that you don't want to close, for example because you are posting on a forum and if you accidentally close the tab you would lose your post content. This is a feature that exists in the Tab Mix Plus addon which doesn't work on the new Quantum.

Could you please add this feature? Thanks!
