Option Freezes on SeaMonkey 2.0.13 Win Rated 4 out of 5 stars
After upgrading Open With to 5.0 , clicking the option button in the add-on manager freeze itself, though browser tabs are still alive.This does not happen with Firefox 4.0 and 3.6.15. Only with SeaMokey ;-((I don't know whether this problem is reproduced on Mac or Linux.)This review is for a previous version of the add-on (5.0.1-signed).
Odd. I'll look into it.
 ... aaand that would be due to me breaking it. Sorry, fix on the way.
