It's basically a pop-up window with the todoist app. Which means it loads just as slowly. If I'm going to wait for 3 seconds for the thing to load, I'd rather visit the full todoist website instead.

I'm not going to evaluate the service itself - just note that it's the best to-do list service I've found. Instead, this is the handiest way to access it. The first time I had my email up and pulled up the add-on, I was sold. It's much more handy than switching between windows. I especially like that it doesn't take up much screen real estate, allowing me to see the page I have open and the to-do list at the same time.

Todoist has helped me keep on top of my todo list better than any other process or app that I have tried. Creating, modifying, completing, and organizing todo items for home and work has never been easier! Love this add-on!

super useful if you use todoist and it's improved even from a year ago

It is great that I don't have to switch between the full Todoist and the site I work on. I just simply click on the icon on the right to watch my today's goals. The whole Todoist concept and app is great as well.

It has become essential for me

I love Todoist. My only complaint is that it does not have 2fa. Add that and it gets 5*, more if it is not just SMS.
