Firefox won't recognise Flash, even though it's installed on my computer.
Firefox keeps telling me I require additional plugins to view media. But when I click on 'install plugin', the install fails and I'm prompted to manually install Flash. But I've done that about three times now, and it still won't recognise it. I know it's installed, because I can play flash using IE on my laptop, but still no luck with Firefox.

There are two different versions of Flash, the ActiveX version for IE and the Plugin version used by most other browsers.
1.Download the Flash Plugin version setup file from here:
Adobe Flash - Plugin version.
Save it to your Desktop.
2. Close Firefox using File > Exit
then check the Task Manager > Processes tab to make sure firefox.exe is closed,
{XP: Ctrl+Alt+Del, Vista: Shift+Ctrl+ESC = Processes tab}
3. Then run the Flash setup file from your Desktop.
4. Start Firefox and test your installation here: https://www.adobe.com/software/flash/about/
- On Vista and Windows 7 you may need to run the plugin installer as Administrator by starting the installer via the right-click context menu if you do not get an UAC prompt to ask for permission to continue (i.e nothing seems to happen).
