Adobe Flash And Chrome

The support of the Adobe Flash plugin is going to end in the year 2020, and that is for all major web browsers (Firefox, Opera, Microsoft Edge, Apple Safari). However, if you save the flash file. Additional warning on Flash Player activation prompt (Target: Chrome 83 - May 2020) Summary When users go to active Flash Player for an origin/ session we will show an additional line of text 'Flash Player will no longer be supported after December 2020.'

1. Since Adobe no longer supports Flash Player after December 31, 2020 and blocked Flash content from running in Flash Player beginning January 12, 2021, Adobe strongly recommends all users immediately uninstall Flash Player to help protect their systems.
2. Use of the software is more trouble than it is worth, and because of this, Adobe recently announced that it will end updates and distribution of the flash player at the end of 2020.

Status

HTML5 by default has shipped and we are currently in the process of ramping up the SEI threshold, per the schedule below.

Currently 87.5% of population have an SEI threshold score of 4 and 12.5% has a threshold score of 8 (we do this to measure the impact of the threshold change). By the end of the month we will progress on to the next phase on the ramp and everyone will be at least at 8.

Shipping Schedule

HTML5 by Default was initially rolled out to 1% of Chrome 55 Stable users (December), followed by a full deployment (i.e. to 100% of users) in Chrome 56 Stable (February).

Flash prompting will only be enabled for sites whose Site Engagement Index (SEI) is below a certain threshold. For Chrome 55, starting in January 2017 prompts will only appear for sites where the user’s SEI is less than 1. That threshold will increase to 100 through October 2017, when all Flash sites will require an initial prompt. As a reminder, users will only be prompted once per site.

Here’s a summary of thresholds and % of users:
