Not well supported.

I love the functionality but this plugin grinds my browser down to a halt. Clicking on buttons within cards takes forever. Moving cards gets wonky. I wish it performed better.

Liked it very much. Thank you team.

Just installed 1.98.2 with Firefox 43.0.1 on Win7 x64. It works but is very slow.

Navigating to a new board in Trello it takes a second for the estimates to appear at the top of the lists, which causes a rescaling of the lists. Also the estimate is displayed in an otherwise blank line beneath the list title instead of on the same line as the list title which wastes a lot of space.

Opening a card and clicking in the title to edit it takes anything between 3 and 8 seconds for the 'estimate points' and 'consumed points' ui to appear which is just not remotely good enough.

I give it 2 stars because it has promise. But it badly needs some fixes.

Very high CPU load. jQuery? Are you serious?!

This plugin decorated Trello like it should. It looks like and looks just the same as the Chrome extension.

The developer also does a good job of updating the extension whenever Trello updates their website and the extension stops working.

However, I have found that if I have Trello open with this extension running (which I always do when I'm working), then Firefox will lag for half a second every few seconds (about once every 10 seconds). This is most noticeable when I am scrolling down a page, the scroll will suddenly judder rather than being smooth.

This has finally gotten on my nerves, and after testing I have decided that the problem is because of this extension. I have decided to live without the extension because of this.

Thanks for the work by Scrum for Trello team.

Tested on version 1.98.2.

Update. Disabling Scrum for Trello didn't seem to entirely work. Despite it being disabled, it was still running on Trello. I had to outright remove the extension to stop it from running.

Awesome thing.
Please add "card counter" and "card separator" (for days of a week). After that it will become Must-Have addon for every Trello accounts.

Had to uninstall immediately, CPU went to 100% and stayed there. Firefox 43.0.4, SfT 1.96.1

The performance problem seems to be resolved. Very useful add-on that helps me plan and track time for Trello tasks

It makes Firefox practically unusable, I'm using Scrummer instead:

Same issue as this reviewer: https://addons.mozilla.org/en-US/firefox/addon/scrum-for-trello/reviews/707596/

I love the chrome version but having this add-on enabled makes firefox unusable.

solid app :)

Trello is a pretty expansive brainstorming tool, but it doesn't have an ability to quantify the projects that are noted. This tool helps to do that. You can create time estimates and they get totalled at the top. You can also go back and enter the actual time and use the information to compare your progress. I dig the concept.
