With 2.13.1 and FF ESR 31.5.3, and given the following combination of settings:
I understand such a visit should be taken into account in the statistics. It seems it is not.
Setting FF to "Do not tell sites anything about my tracking preferences" does track the visit while "Tell sites I do not want to be tracked" is honoured.
I'm using Firefox 38 and it seems they simplified the Do Not Track setting:
@patriiiiiiiiiick with FF 31, when you set "Tell sites that I want to be tracked", can you show a screenshot of your HTTP headers (open console and look for the request in Net panel) for the request to piwik.php ?
@mattab In that case, there is only the piwik.js call, not the piwik.php.
I don't require a fix for this but will only get the new ESR in a couple of months...
Since Firefox changed their UI, and it bugs only with old browser, and it rather tracks less data than more data, I mark as
wontfix. if someone disagrees feel free to comment
