Window: find() method
Non-standard: This feature is not standardized. We do not recommend using non-standard features in production, as they have limited browser support, and may change or be removed. However, they can be a suitable alternative in specific cases where no standard option exists.
Note:
Support for Window.find()
might change in future
versions of Gecko. See Firefox bug 672395.
