Bonjour Je ne parviens pas à télécharger FLASH sur mon ordinateur

dès que je télécharge une pop up fenêtre me propose une application d'essai gratuite d'un mois de 10 photo stock

This is an optional offer that normally displays after Flash Player has been installed.

Most browsers disable Flash by default, forcing users to enable it, depending on the browser, users must enable Flash for each site.

To enable Flash in the browser, see:

• For Chrome/Opera: Use or fix Flash audio & video - Computer - Google Chrome Help
• For Firefox: Why do I have to click to activate plugins? | Firefox Help
• For Safari: Enable Adobe Flash Player for Safari

Of the above support pages do not help, provide the following:

• mac OS version
• browser, including version, you are using
• exact link to content that is not displaying Flash
