An "eideticker" is a person with a photographic memory.
Eideticker is a new performance harness that measures user perceived performance of web browsers by video capturing browser output them in action and subsequently running image analysis on it, as opposed to instrumenting the browser internally and measuring raw result. This is different from most classical performance that wayanalysis, which almost always relies on some kind of internal instrumentation.
Currently Eideticker is oriented around measuring performance on Fennec for Android, but support for other platforms is planned.
