Active page experiments in reverse order depending on the Web Browser you are using

Hi team,

I don't know when nor why anyone noticed this but depending on the browser you are using (in my case Mozilla or Chrome), the Active Page experiments are sorted in one way or another.

(Take the 1st experiment as reference)

Chrome 1st page	Firefox 1st page

Firefox LAST PAGE (Chrome's 1st experiment is the last on Mozilla)

The screenshots were taken from the actual earth.bsc.es autosubmitgui page and it happens also in the dev env.
