So, I tried installing your addon from the Builder website, when it installed in Firefox 14, I only saw the modeDot.
I then forked your addon on Builder and repacked it with 1.6.1 and tried installing that. Still only the dot.
I repacked it with 1.5 and installed that. Only the dot.
So then I packed it back with 1.7 and started fiddling around with the code.
I first switched the <div>s in your widget's HTML file with <span>s and got rid of both of the float attributes in the CSS. When I installed that, I saw the counter, but not the dot.
Then I switched the <span>s back to <div>s and messed with the CSS some more. When I changed it to the following, I saw both the dot and the counter:
<style>
#tickerDiv {
color:#999;
font-family: Arial, sans-serif;
font-size: 1.25em;
cursor: pointer;
}
#modeDot {
border-radius:5px;
height:5px;
width:5px;
background:black;
margin-top:6px;
margin-right:6px;
float:left;
}
#tickerNumbers{
float:left;
}
</style>
I changed it from "margin:6px;" to "margin-top:6px; margin-right:6px;".
The counter doesn't quite seem to fit in the addon bar completely, so I would change the font-size down a little bit and that should be fine.
If you want to let people try it, my fork is here:
