<font size="-1">Hi, <br>
<br>
Is there any reason why by default iceweasel is using Mozilla/5.0
(<b>Windows NT</b> 6.1; rv:43.0) Gecko/20100101 Firefox/43.0 ?</font></blockquote><blockquote type="cite"><font size="-1"><br>
I already have user agent switcher but I don't understand why
iceweasel doesn't detect the OS properly to put Linux instead?<br>
<br>
thanks<br>
