Tab Mix WebExtension will need a complete rewrite of the current code. In order for me to be able to invest the amount of time it will take to develop a new extension, I will need your support.



We continue to improve Tab Mix Plus by fixing bugs and compatibility problems with other extensions & themes, as well as other Firefox's based browsers like Pale Moon, Waterfox, Cyberfox, etc.
