CSS works in IE not Firefox

Hey guys, I’ve got a few lines of CSS that I used on my old site for pullquotes and to float images with captions on the right or left. A sample is as follows:

.imageleft {
background: white;
color:#997A40;
float: left;
font-size: 7pt;
border:1px solid white;
font-weight:normal;
line-height:140%;
padding:5px;
text-align: right;
border-right: 2px solid #666;
}

That’s pretty much the same code for the pullquotes and the rightimage too, and when I make a post I’d use

<p class=”imageleft”><img src=”…”><br>Caption</p>

and it would show up fine on my old site in FF or IE, but now on my new site, it only shows in IE. Anyone have any ideas? I know FF is more picky about code, is there something I’m missing? Any ideas would be greatly appreciated, thanks!
