Hope to be able to use this fine Extension in the near future!! Rated 1 out of 5 stars

I will give more Stars if it can be installed. Unfortunately, when I attempt to do this, I get the following error message:
Not available for SeaMonkey 2.13.2
I would like very much to use this, and will check back.
[edit] After checking on github, I note there is very recent activity on this extension. Perhaps just editing the install.rdf
file might 'do the trick'?[/edit]
