Hi there, I run Firefox quantum 61.0 on win7pro and I would like to customize the icons of my bookmarks.

I found a waay creating the file chrome/userChrome.css in my own firefox profile folder, but it seems not working

After the creation and save of the file I closed and restarted firefox but nothing happened

do you know what I miss or where is my error? thank you!

this is the .css file, copy/paste:

/* First line of userChrome.css must be this: */ @namespace url("http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul");

/* Custom favicon for this bookmark */ .bookmark-item[label="TIM"] image { width:0!important; height:0!important; padding: 0 0 16px 16px !important; background-image: url(data:image/png;base64,iVBORw0KGg....the code run off the page...QmCC);!important; }

Hi. the code runs off the page.like really far as am on a 32"

Might want to update to version 62 by going to Help --> About as there is no reason to help with the code when your going to update and it will break.

So with that being said do up date,

You can check for code here : https://www.reddit.com/r/FirefoxCSS/ also if this has been updated : https://www.userchrome.org/what-is-userchrome-css.html
