On _certain_ fields in my rails forms the backgrounds are yellow. If I  
check the page source there is no clue as to why. However, if I _save_  
the page to disk and then open it in a text editor I can see that the  
affected fields are like:

How/Why are some of these appearing like this? It only seems to happen  
in Firefox, not Internet Explorer so perhaps it’s some browser  
“feature”. But what are the rules? Why only some fields?

Baffled…

Ed—  
I may be mistaken, but if you have the Google Search Bar for Firefox  
installed, then you have an option that is AutoFill.  
This is the ability for Google to automatically fill in fields they find  
on  
a form with your personal information.  
The reason only certain fields are yellow is because the AutoFill  
function  
looks for “typical” id names for the fields in the given form.  
For example, address, city, state, etc.

I bet that is what is you are seeing.

sounds to me like an auto form filler…do you have google toolbar  
extension  
installed?
