By up to date you have 16.0.0.296 and not the current 16.0.0.305 that has been out since Feb 4/5.

Hopefully 16.0.0.305 will be the last critical update from Adobe for a while.

Mozilla like a lot of open source companies does not have the resources to staff large call centers to do one on one phone, email or chat support.

Hi,

The people who answer questions here, for the most part, are other Firefox users volunteering their time (like me), not Mozilla employees or Firefox developers.

If you want to leave feedback for Firefox developers, you can go to the Firefox Help menu and select Submit Feedback... or use this link. Your feedback gets collected at http://input.mozilla.org/, where a team of people read it and gather data about the most common issues.

I still get a msg stating that Adobe Flas Player plugin is vulnerable, and I need to UPD it. I have done so and get this msg all the time. I don't get this with IE or Google Chrome. It is going to drive me away from Firefox, which I like a lot.

IE, Chrome, and Firefox each use different versions of Flash, and the version numbers don't match each other. You need the latest Plugin version of Flash 16.0.0.305 to not see that "vulnerable" message.

Also, Google supplies their own version of Flash with Chrome, and also supplies the updates for their version. Mozilla doesn't do that because Firefox is open source and Adobe Flash is proprietary software that is far from being open source. And Microsoft doesn't do that for IE for their own reasons.

Please check the Firefox Addons Manager > Plugins tab and verify that you do have Flash 16.0.0.305 installed now, and not the older .296 version or an even older version of Flash.
