After upgrading to Firefox 30 it displayed the following splash page: https://www.mozilla.org/en-US/firefox/30.0/whatsnew/?oldversion=29.0.1 Clicking on two of the links on the splash page me warnings that the article "doesn't apply to your version of Firefox" and instructs me to download the beta version of Firefox instead. https://support.mozilla.org/en-US/kb/common-questions-after-updating-to-new-firefox https://support.mozilla.org/en-US/kb/learn-more-about-the-design-of-new-firefox If the articles really don't apply to my version of Firefox, they shouldn't be linked to in the "What's new" splash page. If the do apply to my version of Firefox, they shouldn't have the erroneous warning. This warning disappears if I enable Javascript for mozilla.org, so perhaps it is just a website coding error.
