Where are the updates? Rated 2 out of 5 stars

I used this very successfully for a while but it appears that updates aren't coming. Although my love was for Firefox 3.6 I tried every version of Freezefox from 4 to 4.13.01( It is not 13.01!!) and they all were dismal failures. Although 3.6 is great what are we to do? Run a 20 year old browser? I am now migrating to Palemoon and Mailcatch wont work with any of the newer versions of Failfox or PM. It was a nice ride while it lasted.
