Firefox is deleting Selenium IDE extension on startup

I'm trying to install the Selenium IDE extension with the latest version of FireFox. I go to the install site, it says it installs. The files are staged in the extensions folder. When I restart FireFox, the staged files are deleted, no file is put in the extensions folder and Selenium IDE is not available on the tools menu.

I've tried creating a new profile, uninstalling and re-installing FireFox, copying the extension from another computer. Nothing works

That is a rather old extension: Released December 17, 2012 16.5 kB You can't expect much from such an old extension.

With what Firefox version did this extension work in case you have used it before?
