The "Plugins" table under "Visitors" - "Settings" shows following strange behavior:
See attached screenshot for information. This seems to be related to #1496.
It doesn't get asked in the bug submission form: Piwik version 1.7 is meant. But I'm not sure how long this has been around, maybe I just never noticed.
Thanks for the report, it seems there is a problem indeed.
Cookie and Java - includes IE users, so:
The other plugins exclude IE users. It looks like one non-IE user changed their user agent to masquerade as IE, this means the Flash detection is over-reported (49 instead of 48).
This is confusing to users given that the widget currently has the footnote:
Note: Plugins detection doesn't work in Internet Explorer. This report is only based on non-IE browsers
but is obviously not accurate given the above explanation.
(In ) refs #2962 - no hope of IE ever supporting plugin detection; so disable it from the start
Now... what to do with historical data?
Oh good guess about browser faking IE user agents. Your solution looks good.
About historical data: maybe we can cap the percentage at 100% max if it could be higher for previous days?
I noticed that the value for 100% is displayed as "100" but other values are correctly displayed with % sign "88%"
