The current latest stable version is Firefox 5.
Its requirements are only available at http://www.mozilla.com/en-US/firefox/5.0beta/system-requirements/
Actual: http://www.mozilla.com/en-US/firefox/system-requirements.html lists requirements for Firefox 4.
Expected: for Firefox 5.
Anthony - Do we still use this page? If so, the version number should be removed from the button and the headline.
I guess this is a question for Christian.
I think we shouldn't have a versionless URL for system-requirements since they are tied to Firefox versions, like release notes.
It's actually at http://www.mozilla.com/en-US/firefox/5.0/system-requirements/ as well...I just need to update the .htaccess redirect. I'll do it today, thanks!
Fixed in r91718
Pushed live in r91730.
