The end-of-life date of Flash Player is December 31, 2020. Now Mozilla announces that Firefox 85 will be its first browser to ship without Flash support. In a blog post, Mozilla writes this version will be rolled out on January 26, 2021. The Flash plug-in itself will stop working on January 12, 2021.
Firefox version 84 will be the final version to support Flash. On January 26, 2021 when we release Firefox version 85, it will ship without Flash support, improving our performance and security. For our users on Nightly and Beta release channels, Flash support will end on November 17, 2020 and December 14, 2020 respectively. There will be no setting to re-enable Flash support. The Adobe Flash plugin will stop loading Flash content after January 12, 2021.
