I use this all the time, keeps me organized.

Works perfectly

Makes everything much easier with my tasks :-D

Great job Todoist team! It is so wonderful that you've got the app working for beta, before official 57 launch.

Todoist is a great way to manage all the things you need to do in a day. Their addon is really nice and it easily allows you to link a website to a task.

It works very well in the bar, and it's acessible all the time.

Perfect add-on to supplement the mobile application.

Solid functionality that works as intend.

Support Firefox 57+ with WebExtension API. Just work.

Label, priority and subtopic, you do not need more.

frequently have to log out and log back in to update to latest version...very minor irritation...otherwise great

Simple. Clean. Sync between multiple accounts via projects works great. I use this for everything I need to check off and I love it.

Todoist is one of those apps where you do not need the premium upgrade because you get all the features you really need for free, but you simply subscribe to pay the developer some money, to show him how grateful you are he invested his time to make your life better.

Well done, does what it's meant to do and gets out of the way.
Love you guys !

I Confirm: Todoist is the beautifully simple to-do list built to help you do more and stress less.

This extension works fine and now it is compatible with new Firefox version.

Didn't expect it to be so discreetly pushy, quite flexible and really useful.

Last night (and every night) ToDoist saved my life, on the work floor!

Supports preview of count of Tasks now. There also is a right-click menu for adding a site as a task directly. Really nice.

Yesterday I wrote a negative review as the extension had not been upgraded for FireFox 57. Today it has and I love it. Some semblance of balance has been restored to the universe. I'm sure it wasn't my review. But I've been using todoist for a few years and not having it for a few weeks made it clear how much a part of my workflow it has become.

It's good and handy app, especially with the notification icon to see what's next to do. And it's convenient because it also can installed in android phone and you can get more reminder. :)

The feature that I like most is that by typing a simple sentence I can input a fixed or recurring task. No existing UI beats this in speed.

I've been using this for the past year or so, and it's been working fantastically every day. I'm glad to see it update to support Firefox 57+.

Having used Todoist for Firefox since january, I'm quite happy. The only feature I missed was the integration with GMail, but I discovered that adding e-mails was still possible via the actual extension pop-out itself (when the e-mail is open).
That doesn't provide me with the button in GMail, but I really don't need that.

Besides that, it works great in 57, and I use Todoist so much that I can't imagine not having it.

I use it for several years and I like it as well as todoist service..

The advice from Duncan, here is still true:

In addition to following these steps:
https://support.todoist.com/hc/en-us/articles/208951085

The tl;dr is:

Under Settings - Privacy - History - Exceptions, add and set ALL of the following (not just the http like the doc says) to "Allow"

http://todoist.com
https://todoist.com

Also be sure to add todoist.com to your exceptions for third-party cookie/history managers, and make sure that if you're using "Clear history when Firefox closes" that you're not also clearing your site preferences. Because, well, then you lose your site preferences, like all those handy third-party cookie exceptions you just went to the trouble of adding.
