As new browsers (such as IE9 and Firefox 4) come around, will their privacy features cause Piwik to lose any functionality?
very interesting question.
The big privacy-related change in FF4 is css:visited. Piwik doesn’t use that, so it has no impact on current/future functionality. Most of the privacy-related functionality in IE9 was introduced in IE8 (e.g., InPrivate).
The threats to Piwik functionality are not new:
- browsers that may be configured to block third party cookies (impact: overcounting)
- browsers configured with JavaScript disabled or an extension/add-on that blocks trackers (impact: undercounting)
The workarounds are:
- host piwik on the same domain as the site being tracked, resulting in a first party cookie
- server-side tracking module; impact: inability to collect browser information, but better than not counting at all
