My experience with firefox add-on reviewers has been hit or miss - One of the most frustrating things is that reviews often happen long after your add-on has been published. I'd rather have a longer waiting time, but once an add-on is published then it means it's been approved.
From the developer point of view it means that it's very hard to communicate on releases, because you never know when your addon is going to be reviewed. From the end user, it means that if someone maliciouly changes one of your addons, you may already have updated to that version before the review.
I also feel that the guidelines around reviews aren't well explained, and the reviewers comments are often terse, bordering on the incomprehensible : at least with Apple, you get pointed to which part of the rules they think you didn't respect - with firefox, we often get broad comments that require a bit of back and forth to figure out what it is they're actually thinking is wrong.
This was the old model and it put a lot of pressure on the volunteer add-on reviewers and their were times where the delays stretched out to several months.
Or at least hire review coordinators who can manage the program effectively. Our volunteers review 15,000+ loans a month. Happy to share insights with Mozilla on how to run an effective volunteer community and keep the pipeline flowing.
