Rated 4 out of 5 stars

Great extension. But I have 1 suggestion:

I like how you can go to "Set Icon Color" and change the shape of the HashColoured favicon, but these different shapes should be a part of the package by default. For example if I open 1 tab it could randomly be a red square, but another tab could be a blue diamond, etc.

This review is for a previous version of the add-on (0.4.22).
