The major browser vendors are all implementing click-to-play by default for Flash content. Some more strict than others. For example, in Windows 10 version 1703 (creators update), Microsoft has implemented click-to-play on a per site basis, forcing users to enable it for each site that has Flash, there is no blanket 'always allow for all sites' option.
The 'Allow and Remember' option worked for me after I noticed the lego piece in the address field in your screenshot and selected it. I closed the browser several times and went back to the page and the Flash content did display.
Visiting your site using Chrome also does not display any Flash content and there is no messaging to the user that there should be Flash content. You'll need to code your site to work with these changes being implemented by the browser vendors. The following resources (there are others) may be of assistance to you:
Thanks for the info m_vargas .
I did some checking and found that the requirements were---
For Firefox – Add the “Adobe Shockwave Flash Plugin”. Click on “Activate Adobe Flash”, then select "Allow and Remember".
For Chrome – Go to settings. Open advanced settings. Select “Privacy Content settings”. Enable “Allow sites to run Flash”.
For Microsoft Edge – Go to settings. Open advanced settings. Enable “Use Adobe Flash Player”.
Bit of a drag seeing my site going down hill. I created my own website even though I had no computer HTML or JAVA software knowledge at all. All I had ever encountered was the BASIC and BASIC+ languages of the 70/ 80's. Thus the programming became a "learn as you go" process. Also, due to lack of cash, it was written via the use of nothing but freeware programs, and an outdated Intel 486 computer.
Anyhow, thanks much for the info. I guess we will say, Subject Closed.
