Updating FF causes filter downloads to break.

I updated today on, Monday, March 16. My exact steps were:

Surfed to FF website.
Tried to "Open this filter in Filter Forge" Explosion by Sphinxmorpher.
FF auto-launched.
FF informed me that it could not download any filters unless I upgrade. I clicked okay.
FF crashed. Asked me to submit a bug report. I did so.
Manually re-launched FF. It told me to download the update again. I clicked okay.
This time, I was able to actually install the update.
I went back to the web browser and tried to download the filter again.
Now any time I try to download a filter, it pops me up a window saying:

Initial data download failed. Reason: 'get_families_versions_list() failed.'.
