On a technical side: I came to the conclusion that displaying tabs horizontally is, well, stupid. Displaying them vertically is better. Tree Style Tabs for Firefox allows this. It also has hierarchies and folding. Hierarchies allows me to group related tabs. Folding allows me to "reduce the noise" by collapsing groups. On a personal side: I've learned to let go.
