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:

Having been around since 1996, Adobe Flash Player has played a crucial role in the evolution of the web. For the longest time, before HTML5 became truly widespread, it was the only effective way to run multimedia content online, including video, games, applications, audio, and more.

Today, the era of Adobe Flash Player is coming to an end. While the Flash Player 2020 is still supported, Adobe announced back in 2017 that 2020 would be the last year of support for the software. Accordingly, all major browsers, from Safari to Firefox and Chrome, replaced most of Flash Player’s functionality with compatible HTML5 features. What’s more, Microsoft said it would completely remove Flash from its browsers at the end of 2020.

So why has the internet, which benefited so much from everything that Flash had to offer, suddenly turned against it? In a word, it had a lot to do with security issues and the closed ecosystem of Adobe.

Why Is Adobe Flash Player Going Away?

In his 2010 letter, Thoughts on Flash, Steve Jobs outlined his reasons for Apple’s iOS devices not supporting the Flash standard, which arguably greatly accelerated its downfall. Jobs cited poor performance on mobile devices, frequent crashes, high battery consumption, and availability of better open standards (i.e. HTML5) that are able to completely replace Flash.

In reality, security vulnerabilities have plagued Adobe Flash Player throughout its life, and it has been widely reported to be the primary target for hackers trying to exploit those vulnerabilities, which companies producing browsers and operating systems couldn’t fix due to the proprietary nature of Flash.

Having said that, there are still quite a few reasons for why you might want to use Adobe Flash Player. For example, it could still be the only way some legacy media content on the web (e.g. videos, games) is going to play on your Mac. So let’s look at how to enable Adobe Flash Player in Chrome.

How to enable Adobe Flash Player on Chrome

If you need to use Flash Player today, your best bet is to go with Google Chrome. You might be surprised to hear that the Flash plugin is already installed in Chrome, however, it’s turned off by default — you need to turn on Flash in Chrome Flash settings yourself.

So how to allow Flash on Chrome?

1. Open Google Chrome and go to Settings (⌘ + ,)

2. Scroll down to “Privacy and security”

3. Click Site Settings ➙ Flash

4. By default, there’s a toggle set to the off position that says “Block sites from running Flash (recommended).” Switch it on, so it says “Ask first.”

Now, every time you visit a website that contains something for Flash Player Chrome will ask your permission to play it instead of blocking it. But your settings will only work until you quit Google Chrome. So don’t forget to come back and reset it after.

In case you’re having problems with the Chrome Flash Player, updating Google Chrome could help:

1. Open Chrome and click on the menu button in the top-right corner

2. Click Update Google Chrome, if available. Otherwise, you’re currently on the latest version.

3. Alternatively, visit google.com/chrome and download the latest version of Chrome from there

Remember that Google Chrome will stop the support for the Flash Chrome plugin at the end of 2020, so if you absolutely need to use it, make sure you stop Google Chrome from automatically updating sooner rather than later (and use another browser for day-to-day work). But how do you do that? It’s a bit more technical:

1. Launch Terminal from your Applications ➙ Utilities folder

2. Type defaults write com.google.Keystone.Agent checkInterval 0

3. Press Enter

4. Quit Terminal and relaunch Google Chrome

Note: This command will stop the general Google Software Update script from working, so none of your Google apps (e.g. Google Drive for Mac) will automatically receive updates.

To undo the change and let the Chrome browser update itself again:

1. Launch Terminal

2. Type defaults write com.google.Keystone.Agent checkInterval 10000

3. Press Enter

4. Quit Terminal and restart Google Chrome

How to block websites from using Adobe Flash

It’s likely that everyone who needs to run Adobe Flash Player for Chrome right now has a specific use case in mind, such as a retro online game or an old-school website.

1. Open Google Chrome and visit any website

2. Click on the padlock icon in the far left of the URL bar

3. Select the Flash dropdown and choose Block. If you don’t see the dropdown, choose “Site settings” instead, then find Flash in the list and select Block from there.

How to update Adobe Flash Player for Chrome

Most of the time, when you enable Flash in Chrome, it’s going to be up to date. But, occasionally, you could see a Chrome enable Flash error. To resolve it, try updating your Adobe Flash Player Chrome edition first:

1. Open Chrome

2. Type chrome://components in the URL bar and hit Enter

3. Scroll down to Adobe Flash Player

4. Click “Check for update”

Alternatively, you can simply reinstall your Chrome Flash Player altogether:

1. Visit get.adobe.com/flashplayer/otherversions

2. Pick your OS from the dropdown

3. Select PPAPI as a version

4. Click Download Flash Player

5. Find and install the Adobe Flash Player for Chrome in your Downloads folder
