User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8b2) Gecko/20050524 Firefox/1.0.3 Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8b2) Gecko/20050524 Firefox/1.0.3 If firefox is installed and another application has taken the file association for html files and the protocol associations for http then the only way to change the associations back to firefox is either to wade into the windows filetypes yourself (something that is a pain in the neck to do) or get IE or something to set itself as the default browser so you can then tell firefox to set itself as the default browser and thus set all the file associations correctly. Reproducible: Always Steps to Reproduce: Expected Results: At basic this could be a simple button that restores the necessary file associations to firefox. Ideally it would be a little child preferences that allows you to select which file associations you want for firefox.
