Can't play videos from vk in firefox, but can in chrome or Opera
Several weeks ago, I updated both Flash Player (version 32) and Firefox (67.0.4) on a Windows 7 machine. Ever since, I have been unable to view videos from vk.com. If I click on the video, it goes to the blank screen as though it is going to load, but the blank screen just sits there. There is no error message. Other sites, such as You Tube, seem to work fine. If I access vk.com from either Chrome or Opera, the videos load and play without a problem. On the Flash plugin, I have it set to "ask to activate". It does not ask the permission on vk.com. I have also tried to set the plugin to "always activate", but that does not work either. Since I can load and play the videos on the other browsers, I assume something with Firefox, either in my settings or in conjunction with Flash, is the issue. By the way, I did the upgrades because I got a message from vk when trying to play a video that my Flash was out of date.

Hi reman247, what is a sample address for a page that is coming up blank? In particular, is it a web page with an embedded player, or is the site sending you a media address (for example, a URL ending with .mp4)?
Most sites do not give out-of-date warnings for Flash. Sometimes, unfortunately, that is an enticement to install malware. You might want to do a little cleaning on the side just in case. This article suggests tools that other Firefox users have found helpful: Troubleshoot Firefox issues caused by malware.
I'm having a similar problem. I'm working on creating a website, and have a couple of flash videos embedded in it. I open the test page in Chrome and everything works fine, but when I open it in Firefox the videos don't play. There's just an empty box where they should be. If I right click the space to view page info it acknowledges that there is a Flash slideshow there, it just won't play.
Hi Marklayne, does Flash work in your Firefox on Adobe's test page:
https://helpx.adobe.com/flash-player.html
That page also should also let you know if Flash needs to be updated.
You could check for error messages in Firefox's Web Console. You can open the Web Console in the lower part of the tab using either:
- "3-bar" menu button > Web Developer > Web Console
- (menu bar) Tools > Web Developer > Web Console
- (Windows) Ctrl+Shift+k
Then reload the page in the upper part of the tab, activate Flash if needed, and watch for error or security messages. Anything that sounds like it could be relevant?
Yes. The latest version of Flash is installed, and there is movement in the animation on the Adobe page.
I wasn't sure which page you wanted me to do the web console stuff on, so I did both.
Adobe's page gives me this when I refresh: The script from “https://geo2.adobe.com/json/?callback=showChineseDisclaimer” was loaded even though its MIME type (“application/json”) is not a valid JavaScript MIME type. flash-player.html This site appears to use a scroll-linked positioning effect.

My test page doesn't do
There's no change on my test page.
Is there any reason Firefox wouldn't play a flash element because the page is currently just on my computer and not being accessed via the internet?
When I look at the developer tools it does acknowledge the flash videos, it jsut doesn't play them. There's not even a broken link icon in their places,, it's just an empty space.

Okay, if the Adobe test page indicates you have the latest version (example attached), that is good.

Yes, Firefox only runs Flash served on http:// or https:// addresses. If you need to run flash from a file:// URL, there is a hidden setting for that:
(1) In a new tab, type or paste about:config in the address bar and press Enter/Return. Click the button promising to be careful or accepting the risk.
(2) In the search box above the list, type or paste plugins and pause while the list is filtered
(3) Double-click the plugins.http_https_only preference to switch the value from true to false -- note that this enables any protocol:// any website might use, so it is considered risky and you may want to flip it back while you are not working on your site
That worked! Thank you so much!
Note that Flash is outdated and Flash support will be removed next year and Flash also won't work on mobile devices. Best is to use the HTML5 media player with the VIDEO tag.
