I use a light-grey color for the default foreground color in my OS, with a dark background color. The extensions list uses a hard-coded light-grey background color, but uses the OS's light-grey foreground color for the text, rendering the entries unreadable. Please, either use the OS colors, or hard-code both background and foreground colors. Reproducible: Always Steps to Reproduce: open the extension manager, look at extensions

For a quick fix, to at least make it usable for awhile, add the following to userChrome.css: extension { color: #000000 !important; } I tried to set background-color, but apparently there is some shading routine or something that prevents the actual color from showing up (I set it to #000000 and it came out somewhere around 75% grey)

I think the best fix here is simply to remove the semi-transparent PNG backgrond, which seems redundant on Luna, Classic, etc.

checked in on branch and trunk

Looks like something overwrote the fix, because this problem is back in 1.5rc3 (and presumably earlier). Image is gone, but the list is hard-coded black text on a near-black background (my OS textarea background color).

Chris - what OS are you using and is this with Firefox? Also, if you did what you recommended in comment #1 you would experience this.

My bad, I had reinstalled my OS (fedora -> ubuntu), but apparently kept my firefox settings, including that userChrome.css modification.
