As a courtesy, we have assembled a list of links to "how to enable Flash" as provided by the major browsers and/or Adobe®. The NROC Project is not responsible for the content of these sites, and cannot guarantee that Flash will work in any browser since it is sunsetting in 2020.
In July of 2017, Adobe announced it would end support for Flash in 2020.
In May of 2017, NROC announced that all math courses had been converted from Adobe® Flash to HTML5. (NROC English was not built in Flash.) Member-contributed Flash courses were still available to members with caveats about their future usability.
In August 2018, NROC stopped supporting all Flash-based courses and asked members to install the new HTML5 courses.
In 2020, the major browsers have relegated Flash to an optional setting which can be enabled on a case-by-case basis, and most will completely remove Flash by the end of the year.
