Theme on the broswer doesn't work on the tab groups Rated 5 out of 5 stars

I love the add-on and use it everyday.
A bug maybe is that I select "use the browser theme in the tab groups", but the theme doesn't show in the groups.
How to fix it? thank you!

Change fails to save if FF breaks Rated 5 out of 5 stars

I like speed dial deeply. While, there is a bug. If some changes was made, then FF broke down. After restarting FF, I would find all the changes lost and everything went back.

Can you save the change in time before shutting down FF?
Thank you!

Attractive and Powerful Rated 5 out of 5 stars

It's better than the same add-on in Chrome

i.e., you can use any web pic to become the icon of you favorite website by some tiny trick.
