When i open my browser its working fine , when i am open a website ( https://www.zarifausa.com/products/z-smart-massage-gun )to buy a massage gun , but they are showing me a error , please download flash player error. I also talk with website owner but they tell me , on admin site all is ok . but i dont what is problem with my browser or my computer.
All browser vendors block/disable Flash by default forcing users to enable it. It's up to the content developer to have proper Flash detection scripts to allow the browser to detect the site needs Flash and prompt the user to unblock/enable Flash.

This sounds like shoddy customer support. An end-user is obviously not going to access the site from the admin portal. They need to attempt to reproduce the behaviour your experiencing using the same operating system and browser you are using, not an Admin environment.
