Hint for anyone with FF35+ Rated 4 out of 5 stars

I really like this add-on! It inspired me to put the following in my UserChrome.css file:

.tabbrowser-tab:not([selected="true"]) .tab-content,
toolbarbutton:not([selected="true"]) { filter: grayscale(1) !important; }
.tabbrowser-tab:hover .tab-content,
toolbarbutton:hover { filter: grayscale(0) !important; }
.tabbrowser-tab[selected="true"] .tab-content { filter: grayscale(0) !important; }

Try it out! Perhaps the owners of this add-on can incorporate this into it? =)

Rated 4 out of 5 stars

works as advertised.
i like gray, could be my favorite 'color'.
only wish it affected All 'tool bars'

Does nothing on Waterfox 12 toolbar icons stay colored

It only affects the bookmark toolbar's icons. Works perfectly on waterfox 12 Win7 x64. Contact me on my email for further support.
