+++ This bug was initially created as a clone of Bug #1386934 +++ When using Firefox in Gnome 3 with dark theme the hover background url color is hardly visible on black background.

See the black row in the middle which comes from mouse hover. It's difficult to notice it.

The code which affects it is here but I'm not sure how to fix that properly: diff --git a/browser/themes/linux/browser.css b/browser/themes/linux/browser.css --- a/browser/themes/linux/browser.css +++ b/browser/themes/linux/browser.css .autocomplete-richlistitem:hover, treechildren.searchbar-treebody::-moz-tree-row(hover) { background-color: hsla(0, 0%, 0%, 0.06); <<< wrong color when background is dark border-color: hsla(0, 0%, 0%, 0.1); }

Seems to be there since bug 1295458. Looks like this CSS exists on every platform, and should maybe use system colours on Linux, or something, or maybe opacity?

Thanks, there's the patch attached. Works for me with light and dark themes.
