Notice to mariners: starting with NoScript version 18.104.22.168 (ATM still a RC) and next version of FlashGot (22.214.171.124, most likely) the packages (XPIs) of my Firefox add-ons won’t be signed anymore.
Almost no other Firefox extension gets signed these days (NoScript and FlashGot had been among the earliest and few for a long time), and AMO being the only authorized repository you can install the add-on from by default, there’s little or no point in keeping the relatively expensive and clunky signature machinery in place.
You probably noticed AMO lags quite a lot behind stable versions. That’s because the editorial staff manually checks every line of code published as “stable” for security issues and known performance problems. Therefore, if you’d like to always run the latest and safest (a good idea for a security tool like NoScript), you may want to switch to the fast lane, i.e. the automatically up-to-date beta channel, by installing 126.96.36.199rc1 now.
