After a few years use, I am happy to recommend it still. Updated 30.09.2023

Just started using this. There are just a few simple settings to adjust things like volume etc. It's very easy to use and has already notified me of a survey I would otherwise have missed.
Update.
In the last three hours I have been notified of three studies that I would not have known about. I check Prolific once a day at most, so if this add-on continues to work I am likely to do a lot more of them. Well done Prolific.
