Chrome: How to allow Flash on sites

Google Chrome

Google Chrome blocks Flash content by default in recent versions of the web browser. Google furthermore removed controls from Chrome in regards to plugins and Flash, and will remove Flash support from the browser in the coming years as Adobe announced the retirement of Flash by the year 2020.

Google Chrome's current behavior when it comes to Flash is to block the execution, and prompt users whenever Flash content is encountered. The browser prioritizes HTML5 content when it is available over Flash content.

While this works at times, it does not at others. The prompt may not be displayed and users are without controls then to enforce the running of Flash in the browser.

Google integrated Adobe Flash natively in Chrome back in 2010, and it has been part of the browser ever since.

Chrome: How to allow Flash on sites

chrome flash allow prompt

Flash content is not allowed to run by default in Google Chrome. Sites may display notifications about that on their pages, like "click to enable Flash Player" or just a button to enable Flash.

You can click on this, and then on the "run Flash" prompt that the browser displays near the top of the interface to run the content that time.

run flash chrome

The Flash content is loaded in the browser if you select allow, and not loaded if you dismiss the prompt or select block instead.

The notification that is displayed instead of the Flash content is not displayed all the time. You may also need to click on the "get Adobe Flash" button instead, or may find yourself in a situation where you cannot activate Flash at all.

Update: Google Chrome allows Flash to run only for a browsing session since Chrome 69. The method outlined below to allow Flash content to run on a site permanently does not work anymore in recent versions of the browser.

Starting in Chrome 76, Flash is blocked by default. Chrome users may still enable it, but Chrome will display a notification about the end of Flash support in 2020 in that case in every session.  End

Old information

While you can allow sites to run Flash when Google prompts you to do so while visiting a site with Flash content, you may want to allow Flash on some sites permanently to make things easier. The latter may also be important for sites that don't work properly in regards to allowing Flash content, for instance when Chrome does not display the prompt.

allow site flash chrome

You can configure sites to run Flash automatically in Chrome. Here is how that is done:

  1. Load chrome://settings/content/flash in the browser's address bar. This opens the Adobe Flash content settings.
  2. You can change the status of Flash by moving the "ask first" slider to off.
  3. To add a site to the allow list, click on the "add" button next to allow, and add a site to the list. You can use [*.] for that, or enter instead.
  4. The same rules apply to sites that you want to block from running Flash content.

A click on the three dots next to a site listing gives you options to edit, remove or block sites (allow if you click on the three dots next to a blocked site).

Now You: do you visit sites regularly that require Flash?

    I have “Allow insecure content, and changed Flash to Allow yesterday. Logged off, and now the Allow Flash is back to block. Allow insecure content is on for Flash, but I still can’t play the game until I AGAIN, go in manually and take off the Block on Flash and Allow Flash!!!

      Flash is on its way out at the end of the year and it is no longer possible to run Flash automatically on sites in Chrome (you always have to allow it).

    thank you man! this was helpful!

  3. Eli said on February 2, 2020 at 9:32 pm

    chrome://settings/content/insecureContent This is the correct and direct address to do this. You will immediately see options to add and block content, with the “add” buttons THERE. Just add and paste the site URL.

    If you go to chrome://settings/content/ …just scroll allt he way down to “insecure content”, and you get the same.

    Makes me mad that Chrome makes it so hard. I was searching forums for an hour before figuring this out…thought I’d share in case others still need it.

    Can tech help sites stop lying to their visitors or at least update the damn information so that you aren’t lying by accident?

    1. Martin Brinkmann said on February 28, 2019 at 7:50 pm

      Which part is incorrect?

      1. John said on August 16, 2019 at 5:05 pm

        There is no allow button

      2. Diane said on June 21, 2020 at 1:47 am

        Correct ….. there is no add button to add a site to Flash. There only is on Javascript!!!

    Thanks Martin, for the awesome article. I would just like to thank you for the awesome and updated article that you have published everyday. Even though I cannot support you on Patreon, I have disabled adblock on your site. As that is the least I could do. :)

    Yes I prefer flash to HTML5. Its just most controllable than HTML5. HTML5 n many browsers is harder to control, harder to block, harder to manipulate than flash with the multitude of tools that have been made available for it. In recent times flash hasnt been all that unstable either.

    The major frustration that came with using flash was when it crashed the whole browser went down taking with it inumerable other things. In modern times though sessioning has made that at most a minor inconvenience.

    If they start adding controls to browsers that allow manipulation of HTML5 that is equivalent to flash, no problem. Until then many people will keep the devil they know.

      You can’t control flash because it has low level access to your memory similar like JavaScript and that’s what can be abused. HTML5 don’t allow that so you’re wrong to think just because there some fancy control buttons that this changes anything. Flash is just horror, not only because DRM or CPU consumptation it’s horrible to maintain as developer because there only closed source tools which you are forced to use and they mostly have strange dependencies.

      1. ShurikMur said on March 23, 2018 at 7:23 pm

        You are definitely not a developer. Flash was much, much easier to program than JS (with so many open standards and browsers at the same time…) and it also was faster, including trivial video playback.

      2. Rush said on November 3, 2017 at 7:19 pm

        As a developer, I would be lucky to score just a c+ then a c++ so, I am not a programmer. But as far as the eye test…With respect to CHEF, I would have to agree with joji.

        Flash is in constant need, changing of its underwear for reasons of security and that is bothersome, and I prefer HTML5 but in addition, I also have the need to choose from time and place to approve flash during my session. This has always worked best for me.

      3. joji said on November 3, 2017 at 6:03 am

        This is wrong, you’re clearly not a developer. Flash programs use action script, similiar to JavaScript and both don’t have low level access to memory. Google low level programming for more details.

        HTML5 or canvas also have DRM, Google for more details.
        HTML5 or canvas also can get High CPU usage, Google for more details.

        It’s horrible to maintain because it’s closed source? Strange dependencies? I really don’t understand this sentence. Many popular frameworks are also closed source, .NET Framework and Unity are closed source for example.

        HTML5 is made to make users have less control just like db said

  11. CHEF-KOCH said on November 1, 2017 at 10:20 pm

    Let this mofo die, don’t allow it, don’t install it and don’t touch it.

  12. Patrick said on November 1, 2017 at 7:23 pm

    If a site requires flash, I move on. The *ell with flash.

  13. Sampei Nihira said on November 1, 2017 at 6:46 pm

    Make a test before setting “ask first”:

    repeat the test several times.

      chrome://settings/content/insecureContent ….go here. This is where the add/block content switches are WITH the buttons
