I got a new Dell laptop for Christmas and started using it a couple of weeks ago. Loading Firefox was one of the first actions I took. I have a McAfee subscription so I signed into my McAfee account so I could add it, and got a message asking if I would like to install McAfee Web Boost, an extension that automatically pauses videos unless I tell it to play them. I have a data cap, and this extension would help a lot with my data usage. I told it to install, and and it worked like a charm. My wife asked if I could install it on her computer, too. Here's where it gets weird. It's not in Firefox's list of extensions! Since McAfee loaded it on my computer, I contacted their tech support, asking it how I could load it onto my wife's Firefox browser. I was told the extension was for Chrome and they didn't make one for Firefox. I spent several minutes trying to tell the tech their Web Boost loaded into Firefox, the icon is there among my extensions, and the damn thing works. All the tech could do was load the extension into Chrome, which my wife hadn't uninstalled from her machine. The extension obviously works with Firefox, so how can I get it onto my wife's computer? The version is 1.0.0.25006.
