Great tool, and I've been using it for years, but the latest firefox update has broken it yet again. :( Getting the dreaded: WoaS: Unable to save file... Your browser might not be supported, please report a bug with your UserAgent string: Mozilla/5.0 (Windows NT 5.1; rv:23.0) Gecko/20100101 Firefox/23.0 The original devs seem to have disappeared, but I read a while back of someone working on a fork project from this one. Unfortunately I can't find the site anymore. All WoaS needs is some occasional support to keep up with the perpetual "security" fixes in all the browsers.
