I'm just rounding up my main switch back to dear Opera 9.50b, having being lured to FF for a couple of months. However, using a rich formatting tool at a swedish blogg portal creates <p> tags when pressing enter instead of <br /> as in FF (which i find easier to read. The <p>-tag also brings other undesired design elements). I don't know how to describe it further (as i'm no good at coding), so I'll just post the code using 1. Firefox and 2. Opera
The same thing seems to go for Gmail as well.
Firefox
CODE
Whatever<br />Whatever2<br /><br />Whatever3
Opera
CODE
<p>Whatever</p><p>Whatever2</p><p> </p><p>Whatever3</p>
In other words, I want Opera's <p>text</p> to Firefox text<br />
