Wasn't it a fun Friday? It started with a legit Nikon upgrade, followed by a legit Adobe Flash upgrade, followed by not being able to get to a web page so I launched Firefox to see if it was Chrome or my ISP (they've recently started blocking various web sites for a day or so, and I don't know why). Launching FF brought up an alert about what I thought was a legit update to an extension I had installed, and I wasn’t really awake, so I said yes to all these upgrades/updates.
- The Nikon was legit and needed.
- The flash was legit, but not needed and it’s now uninstalled. (Thanks xABD!)
- The FF extension alert wasn't legit (and wasn't an upgrade to what I had installed)—it was malware, and it’s now banished; but banishing wasn't easy.
The malware was “install.mac”. I tried following directions on the apple support forum, and could not find all files and so it kept reinstalling its nasty self.
I went in and reset FF to default and hoped that would take care of problem. It didn't. I finally gave up and used my cloned SuperDuper backup to restore my harddrive to last nights clean state.
Now that I've installed the clone, I just launched FF and the very same install alert showed up. The extension is "flashandvideo". I'll attach a screen capture. Not gonna snag me twice.

I've learned my lesson though: don't install ANYTHING before my morning coffee.
