have a new Acer Aspire laptop on Windows 8.1, running the latest Firefox as default browser. On trying to open Al Jazeera in Firefox I get a window that says I need to download Adobe Flash Player, screenshot 2. I click on that and get the Adobe download page, screenshot 3. I click on install now and get the prompt to save install_flashplayer, screenshot 4. I click on save file and then go to my downloads folder and it has the installer icon there, screenshot 5. However when I then double click on it nothing more happens. A window headed Adobe Flash Player Installer with no content appears, screenshot 1. And nothing more happens. However if I try and download Adobe Flash Player in Internet Explorer I get a message that it is integrated with Internet Explorer in Windows 8, screenshot 6. Please advise.
