Brilliant but some problems with the dev version Rated 5 out of 5 stars

One of my must have add-ons for firefox, it makes managing and reading feeds simpler and more comfortable.
I just checked out the development version and the new gui looks great, but sadly my old feed database is not recognized/ my old feeds do not show up in the dev version. If I revert to the regular version the feeds are there again. I hope the developer can look into this, since I'd really would like to work with the new gui. I'm using firefox 24 esr.

This review is for a previous version of the add-on (1.7.2).
