Hi littletinyfish, Firefox automatically blocks links. So to allow Gmail redirects, you should add an exception like explained [http://mzl.la/1BAQuEQ here]

See: *Firefox > Options/Preferences > Advanced > General : Accessibility : [ ] "Warn me when web sites try to redirect or reload the page" The setting in "Options > Advanced > General" is meant as an accessibility feature, as you can see by the label of that section, so that people with disabilities or people who use screen readers do not get confused and is not meant as a safety protection to stop redirecting.
