I signed into Firefox on a lab computer that has too little storage space to install plugins (<1MB storage space left.) Naturally, plugins did not install. I wanted to ensure that Firefox would not even attempt to install them in the future, so I set the browser not to sync add-ons. I don't know whether what follows is because of that setting, or because I set it too late. In either case, my dozen or so plugins on my main computer have now all been uninstalled. I don't know the names of all the plugins I was using anymore. 1. Can I recover my automatically uninstalled plugins? 2. Can this bug be patched?
