You should be able to activate the plugin(s) from the plugin manager. To do so, please follow these steps:

1. Go to the addon manager or enter about:addons in the address bar
2. Go to the Plugins section
3. Locate the disabled plugins
4. Select Always activate from the drop down menu

This should automatically activate the plugin(s), but if it does not or if the option is not available, please check if all your plugins are up-to-date. Firefox will not allow you to always activate plugins that it knows are out-of-date, as this would be a potential security risk. Therefore, you will have to update the pluglin(s) before you are able to activate them. To do this, go to the Plugin Check site.

Once you're there, the site will check if all your plugins have the latest versions. If you see plugins in the list that have a yellow Update button or a red Update now button, please update these immediately.

To do so, please click each yellow or red button. Then you should see a site that allows you to download the latest version. Double-click the downloaded file to start the installation and follow the steps mentioned in the installation procedure.

Note: If your version of a plugin is newer then the one shown by the test page, do not worry about it. This just means the plugin you have is a recent update.

If the updater shows Unknown, this plugin is not on the testers list. To check that plugin, go to the home web site of the owner of that program.

I did all of that, but not knowing what plugins are required for my Fluenz program to work correctly, and not knowing where to go to get the right ones when they are not on my computer makes it a "no-go". That probably all makes sense to a technically competent user, but to me - the average Joe - it is too much. Google Chrome "just works", without asking me to be a knowledgeable techie. Sometimes the ideas of technical complexity just overwhelm the utility of a product. That seems to be the case here. More is less.

http://fluenz.com/fluenz-support/ Are you using Fluenz 2 or Fluenz 3?

> What’s the difference between the old Fluenz f2 and Fluenz3?

"The old Fluenz f2 was based on Adobe Director [which you don't seem to have installed] and ran off a DVD or could be installed directly in the computer. It had no syncing, tracking, auto-updating, or the ability for users to manage their content from their Fluenz ID. The most important issue is that Adobe discontinued Director and any program built with it, Fluenz included, was facing increasing issues of compatibility with different operating systems."

"The new Fluenz3 runs on HTML5, is compatible with the next generation of operating systems, and allows users to manage their content from their Fluenz ID. The program tracks and syncs the user’s progress across all of the Fluenz access points (online, iPhone app, iPad app, and Android phone app) and allows users to move their content from computer to computer quite seamlessly. Because it works like an app installed in the computer’s hard discs, Fluenz3 also works offline." Issues with Fluenz 3 wouldn't be "Plugin" related as Fluenz support told you.

Firefox HTML5 compliance can be viewed here: https://html5test.com/ - when you go there with Firefox. HTML5 Speech Recognition and Speech Synthesis isn't supported in Firefox, as of yet. And I assume that "language learning" application might need "recognition" and "synthesis".

It would help it a company that "prominent" provided better information to their users. Better than talking about Plugins and not telling you which of the 3 "Adobe" plugins (Director, Flash, or Reader) are required for Fluenz2 or not mixing that incorrect "Plugin" info in with what is needed for using Fluenz3 - HTML5 compliance. Mixing up information for non-technical users only serves to confuse the issue when a user reads support info or asks for support, IMO.

Probably why they recommend Google Chrome which is ahead of Firefox with HTML compliance, by a wide margin currently.

Thanks for the responses. I am using the newest online.Fluenz3, which is entirely online rather than based on my hard drive. It is smooth and fast when used with Google Chrome, but is intended for Windows 10 machines. My primary PC is a Dell Inspiron Laptop which Dell - in their infinite wisdom (and arrogance) - has a BIOS that is not compatible with Windows 10 (and will not be upgraded - thanks Dell!) Since I can't upgrade it to Windows 10 I have left it on Windows 7. I can make most of the program work satisfactorily on this machine, except for the microphone audio input, which remains a mystery. I have liked FireFox and am frustrated by not being able to make it work with Fluenz3 online. Of one thing you can be sure - I will NEVER own another Dell machine. Oh, well. No-one ever told me that life would be easy!
