Flash was once one of the foremost web technologies. It enriches websites with exciting multimedia content. As such, it remains the most essential browser plug-in.
However, the foremost browser publishers (Mozilla, Google and Microsoft) have largely abandoned plug-ins in favor of HTML 5. Flash is one of the few plug-ins that browsers still widely support, but Adobe has confirmed it will discontinue Flash in 2020. Consequently, Edge, Chrome and Firefox no longer automatically run Flash by default. Instead, you need to select to unblock Adobe Flash content on websites open in Edge, Chrome and Firefox.
1. Unblock Flash in Edge
For example, Flash content doesn’t automatically run in Edge even with the browser configured to utilize the plug-in. Instead, the Flash content will include an Enable Flash option on it. Then, when you press that button, an Adobe Flash content was blocked dialog box opens as shown in the snapshot below. Then you can select to either Always allow or Allow once to unblock Flash for the site open in the browser.
If an Adobe Flash content was blocked dialog box doesn’t open, then you probably need to switch Edge’s Adobe Flash Player setting on. To do that, press the Settings and more button at the top right of Edge. Select Settings > View advanced settings to open the options below. Then switch the Use Adobe Flash Player setting on.

2. Unblock Flash in Chrome
Google Chrome also runs Flash on a click-to-run basis only these days. The browser highlights Flash content on pages with a jigsaw piece icon. So, to run the Flash in Chrome page tabs, you’ll need to click the jigsaw piece icon and press the Allow button. If you can’t select the Allow button to run the multimedia content, you might need to configure Chrome’s Flash settings as follows.
- Press the Customize Google Chrome button to open the browser’s menu.
- Click Settings to open the tab shown in the snapshot directly below.
- Scroll to the bottom of the page and click Advanced.
- Then click Contents settings and select Flash to open the options shown in the snapshot directly below.
- You can unblock Flash by switching Block sites from running Flash to Ask first (recommended).
- You can also add websites to the Allow list to enable Adobe Flash to always run on them. To do that, click Add, input a website URL and press the Add button.
- Earlier versions of Chrome (such as 57) also include an Allow sites to run Flash option you can select to automatically activate Flash for all sites. However, the most update Google browser no longer includes that option.

3. Select Always Activate Flash in Firefox
Mozilla also readjusted Firefox’s default Flash configuration to Ask to Activate in 2017. Thus, the browser displays an icon in place of the Flash multimedia when you open a page. Clicking that icon and selecting Allow unblocks the multimedia content. You can, however, still adjust Firefox’s settings so that Flash is automatically activated on sites as follows.
- Press the Open menu button at the top right of Firefox’s window.
- Click Add-ons to open the tab in the shot directly below.
- Then select Plug-ins to open the plug-in list shown directly below.
- Select Always Activate on Flash’s drop-down menu.
So that’s how you can unblock Flash in Edge, Google Chrome and Firefox. Note that you can also play Flash video content with the NoPlugin Firefox add-on, which converts plug-ins to HTML 5.
