How do I change the Library highlight color for a folder (left panel) to make it more visible while working in the right panel on bookmarks?

more options

When I am working with many bookmarks in the right Library panel, I can't see well the highlight color for the folder I'm working in on the left panel. With folders organizing similar website bookmarks, I need to see clearly the highlighted folder on the left. The current color is too dim. Is there a setting in about:config or somewhere else that needs to be tweaked to adjust it?

You could set a different highlight in a userChrome.css file. The names of the elements:

treechildren::-moz-tree-row(selected) {
  background: #129900 url("chrome://global/skin/url-hover.png") repeat left top;
tree[seltype="cell"] > treechildren::-moz-tree-cell(active, selected, focus) {
  background: #129900 url("chrome://global/skin/url-hover.png") repeat left top;
}

tree[seltype="text"] > treechildren::-moz-tree-cell-text(active, selected, focus) {
  background: #129900 url("chrome://global/skin/url-hover.png") repeat left top;
}

Those are lines taken from the tree.css file of a theme I am using. You can use a background colour or a background image or both.

Thanks for the link to http://kb.mozillazine.org/UserChrome.css where I found another link to userstyles.org, the web site where I found my answer. I installed stylish for Firefox and found a style for the Library. Thanks so much!
