Great addon. I've been using the nightly version built from git with no issues using Firefox 4b*pre. I don't use a whole lot of scripts, about 30, but I have not experienced any problems, even with the large and complex ones.
I guess people are leaving bad reviews rather than reporting issues so they can be addressed because...well I'm not going to get into that. I do wish for the old script manager back though, if only for the fact that the new add-on manager is slow, cumbersome, and generally terrible. The little window was so much quicker... Hopefully it will get better!
Thank you for this awesome free add-on that opens up so many new options. Keep up the good work!
