title: Is firefox refreshing pages by itself ?
body: <p>I'm wondering something about firefox because of a php code. To make it simple, here is the action. In a page I have a php condition : if action is called, then sql, else show page content. </p>
  
  <p>The thing is, when I'm using it (chrome on a mac), everything run perfectly. But when someone else (Firefox on a pc, tried on two pc), it looks like firefox run the condition (so the sql), refresh the page (even if there is nothing that refresh the page in my code) and re-run the sql because the action is still called. So, the action is called twice (but not more) same for the sql. </p>
  
  <p>I made something with my sql (like verify if the id or something else exists, if yes, don't run the sql). But I don't understand why firefox would refresh the page or run the php twice. Any idea ?</p>
  
  <p>NB : the code is messy so I'd rather not post it here and, as I said, it contains no refresh/redirect line. It's just to know if someone saw that before or is anyone has an idea about this on firefox. </p>
  
  <p>Thanks.</p>
