Been using this extension for years and it is amazing. Wasn't sure where else to report this but recently the scroll bar has disappeared making it difficult to navigate.

not working with latest version of firefox. eating up all memory

Works great, just wasn't for me and created a lot of lag.

I've been using this extension at work for over a year now. It is perfect for when you need to work in many tabs at once. But for my personal computer I don't find it necessary, and prefer to use classic horizontal tabs.

Game-changing add-on! This is definitely my favorite extension.

On it's own it's an incredible add-on, however if you take the further extensions into account it turns it into a serious 10/10.

The extensions that you can install, especially the core extensions maintained by piro themselves, makes it the main reason why I even use Firefox at all.

Using the multiple tabs handler, More Tree Commands, and the bookmark subpanel, makes researching topics a breeze. You don't have to struggle with the browser and can get on with your work.
