This feature is non-standard and is not on a standards track. Do not use it on production sites facing the Web: it will not work for every user. There may also be large incompatibilities between implementations and the behavior may change in the future.

Obsolete since Gecko 51 (Firefox 51 / Thunderbird 51 / SeaMonkey 2.48)
