Rated 4 out of 5 stars

Good collection of icons, but makes Firefox significantly slower.
I wish author added two things
* Granular control of CSS rules (to drop some cutiness in order to increase responsiveness)
* Option to disable cute checkboxes.
Otherwise very well done!

This review is for a previous version of the add-on (0.2.7). 

it's all kinda mashed into one big file and i'm working on that checkbox option

if you'd want to send me an email with your specs (hardware / os / fx version) then we could see about doing something, but it is a big file...

and thank you
