i take that back about them updating the message explaining delays may be possible, as i submitted a new update to my extension a few days ago, as the one i was waiting ages to get approved was already way out of date, and i got the same old this addon may take a few hours or a couple of days to get approved message via email…
this is so ridiculous, in this day and age of rapid release cycles, the mozilla addon manual review queue is a serious bottleneck and a huge impediment to developing extensions that need to adapt rapidly to changing circumstances. there must be a better solution.
in the meantime im having to direct users to either use the greasemonkney script version of my extension or change to using a chromium based browser, where add-on updates are approved at a much faster pace.
