How do I adjust the security settings to allow an update on Adobe Flash Player?
good question
Firefox doesn’t like Flash Player any more.
If this is still Microsoft Security Essentials you shouldn’t have to.
You might have to tell Firefox it can let the Adobe sight launch pop-ups. I can look that up for you if you like. (I use Opera and Chro-magnum)
FF blocked Flash because Adobe hadn't patched a zeroday..
First thing - on right hand side of the whatever they call it bar at the top is a box that looks like three horizontal lines. Click that and you'll get a box with settings in it. First thing to check is if Flash is installed as a plug-in. Click Add-ons and you'll get a page that has five items - click plug-ins for a list of those that are installed (usual ones would be Adobe Acrobat, Flash, and Java). The current version number for flash is 18.0.0.209. Click the 'check to see if plugins are up to date' thing at the top. If any are flagged as out of date, tell it to download the update. You will need to restart FFox after the updates to enable them.
If the present version of flash is vulnerable replacing it with the fixed version should allow flash to run. You might get a nag thing asking you to 'allow' flash each time.
Let me know if that fixes things.
