so much better having tabs down the side than in a row that changes size and then has to scroll sideways. If only FF would let us remove them.
TreeStyle Tab also lets me have nested tabs so it keeps threads together as I search and browse links.

Merveilleuse et si pratique extension. Un énorme merci à vous !!!

De las mejores extensiones para Firefox. Tremendamente simple pero muy útil. Agrupa las pestañas de una forma muy cómoda. Obligada.

Удобное расширение. Пользуюсь уже очень давно. Хотелось бы чтобы добавили возможность выгрузки вкладок и групп.

I usually work with a high number of tabs, and i appreciate the structure this plugin brings into my everyday.
I use the user chrome workaround to get rid of the default tab and plugin header.

Its THE best FF extension, but today it just disappeared from my browser and cant re-download it from here? WTAF?

Not quite a replacement for Tab Mix Plus, but I really like the ability to organize tabs into folders. When jumping between tasks, it's easier to find related tabs. I even realized that I had a few nearly identical tabs after organizing them.
