Over deze add-on
The purpose of this extension is to do one thing and do it well: provide tab switching using the mouse scroll wheel. I have found that while I enjoy all the extra functionality tab-focused extensions provide, tab-bar scrolling is the one function I really miss when it's gone. Simple preferences are provided for changing the direction of tab switching as well as whether scrolling past the ends of the tab bar wraps around or not. It is based on Dorando's old miniT extension.
