Firefox 23 mixed content blocking and Galaxy

The Galaxy genomics workbench has problems with mixed content blocking in Firefox 23 when it’s running under https, which it should be based on sending logins and passwords. When you click on any of the public data sources (e.g. UCSC Tables) under Get Data, Firefox blocks it. ┬áThe solution is to turn off mixed content blocking, as described here.

Unfortunately, this is a global configuration rather than per domain.
