hello, this is an error on the sever-side - there's nothing you can do on your end to solve the problem at the moment. the problem is already known and getting worked upon, hopefully it will get fixed soon...
The Plugin check part is working fine now, but Firefox ix not checking Extension updates:
by clicking "tools", "add ons", and check Extensions in Firefox 18.0.2, the program shows the phrase "No updates found".
I know this is not the case, because I am using extensions that I have already verified with their maker that there are newer versions released. For example "NoScript" extension. I have installed version 18.104.22.168, and there has been several updates to it already (the latest released version is 22.214.171.124).
hello, those updates are fetched from the addons.mozilla.org page - the noscript version listed there is also still 126.96.36.199 at the moment. updates get reviewed by mozilla and it takes a few days until they get generally distributed (188.8.131.52 was uploaded to the site just yesterday)... so nothing out of the ordinary there that should worry you.
