I'm creating an extension and using JS to open a new window. I've tried a variety of forms including something like: window.open("https://www.FOO.com" + dest,,"_newtab") and just window.open(url).. The option is set (tools/options) to open in a new tab. I've looked at preferences and forum suggestions to no avail. The proper url opens in a new window instead. I've disabled all other addons and plugins. I suspect I'm doing something silly, but would appreciate any insights. Thx, --Don
