Noia 4 1.7.4 Rated 5 out of 5 stars

Problem seems to have been resolved as Mozilla released the above version(1.7.4) for Download.
All is well, Finally! :)

Those problems seem to happen whenever you take a day off or go on vacation, so that means No more time off for you, Aris!

You have to make yourself available 24/7 and have your cell phone on at all times! :)

This review is for a previous version of the add-on (1.7.3).  This user has other reviews of this add-on.

I don't know what was wrong with Mozillas servers, but after I uploaded v1.7.4 on 08-23-2012 it could be installed at least the same day. ;-)

Edit
No more free time for me or finding a better solution...

I've added a link to Mozillas official FTP servers (where they store the uploaded files) inside short description on top of Noia 4s AMO page.

It should still be possible to download latest files from there, even if AMO has connection issues again.
