Hi, I have a problem with tables background color setting.
Like when I create a new custom block, I insert there .html code for a new table and set its background color with this tag: . The thing is that it looks great when browsing with iExplorer, but when use Mozilla Firefox it doesn't show no background, it's just white. It's not about colors for sure because I use those colors for other parts of the theme and it works great. Can anybody help me?

Thanks in advance
