In particular, Adobe has announced in the middle of last year that it will completely abandon Flash at the end of 2020. Until then, it will only provide security updates and will no longer have major functional changes.
Flash used to be the cornerstone of the Internet and made indelible contributions to the development of the Internet. However, with the development of the era, Flash technology has gradually fallen behind, and the security loopholes are endless. As a rising star, HTML5 has completely surpassed it and withdrawn from the historical stage. In reasonable terms.
At present, all major browsers are gradually giving up support for Flash, which is no longer enabled by default. The next two years will gradually be completely separated from it.
