I have a page that won't load after I allow Adobe Flash to run- how can I fix?

more options

In the past, I've been able to use a site that requires Adobe Flash to run but, now it does not load the page information I need.

Now when I select Adobe Flash to run, the page does not get loaded with the information for that site. How can I fix?

Hi jyeretsian, does the page show you an error message, or do you get a blank area where the Flash content is supposed to load, or something else?

After giving permission, try reloading the page bypassing the cache. Either:

  • Shift+click the Reload button in the toolbar
  • Press Ctrl+Shift+R
  • Press Ctrl+F5

Same problem?

Does the page work normally in Edge or Internet Explorer?

jscher2000....thanks for responding. I get a blank area. I tried the different ideas you had for Firefox but, did not work.

Tried IE and no issues. Did Firefox change something?

There are hundreds, maybe thousands of changes in Firefox in a major update, so lots of things change every other month.

When was the last time it worked?

Some issues may be specific to Flash and what it is allowed to do, while other issues may be related to the connections Firefox makes to retrieve content for the Flash plugin. It can be hard to sort out without additional information.


If a site is generally known to work in Firefox, these are standard suggestions to try when it stops working normally:

Double-check content blockers: Firefox's Tracking Protection feature and extensions that counter ads and tracking may break websites that weren't built to operate normally without the blocked components.

Do you see a shield icon toward the left end of the address bar, near the lock icon? More info on managing the Tracking Protection feature in this article: What happened to Tracking Protection?.

Extensions such as Adblock Plus, Blur, Disconnect, Ghostery, NoScript, Privacy Badger, uBlock Origin or uMatrix should provide toolbar buttons to manage blocked content in a page. There may or may not be a number on the icon indicating the number of blocked items; you may need to click the button to see what's going on and test whether you need to make an exception for this site.

Cache and Cookies: When you have a problem with one particular site, a good "first thing to try" is clearing your Firefox cache and deleting your saved cookies for the site.

(1) Clear Firefox's Cache

See: How to clear the Firefox cache

If you have a large hard drive, this might take a few minutes.

(2) Remove the site's cookies (save any pending work first). While viewing a page on the site, try either:

  • right-click (on Mac Ctrl+click) a blank area of the page and choose View Page Info > Security > "Clear Cookies and Site Data"
  • (menu bar) Tools > Page Info > Security > "Clear Cookies and Site Data"
  • click the padlock or "i" icon in the address bar, then the ">" button, then More Information, and finally the "Clear Cookies and Site Data" button

In the dialog that opens, you will see one or more matches to the current address so you can remove the site's cookies individually without affecting other sites.

Then try reloading the page. Does that help?

Testing in Firefox's Safe Mode: In its Safe Mode, Firefox temporarily deactivates extensions, hardware acceleration, and some other advanced features to help you assess whether these are causing the problem.

If Firefox is not running: Hold down the Shift key when starting Firefox. (On Mac, hold down the option/alt key instead of the Shift key.)

If Firefox is running: You can restart Firefox in Safe Mode using either:

  • "3-bar" menu button > "?" Help > Restart with Add-ons Disabled
  • (menu bar) Help menu > Restart with Add-ons Disabled

and OK the restart.

Both scenarios: A small dialog should appear. Click "Start in Safe Mode" (not Refresh).

Any improvement?
