want to check adsense earnings from FF

Hi, Im using now FF 9.0.1, can someone help me please to get an add-on to check my adsense earnings?

thanks

why do you need an add-on to check adsense earning? why don't you log-in to your account and look at there?

because simply I log in to my account a lot of times, I want some add-on like adsense notifier, but this add on is not supported on FF9. I found a great tool called 'Adsense publisher toolbar by google' but it is available under chrome only, so please help me if you have an add-on supported under FF9

There was such add-on a few years ago, but I don't think it is being supported anymore.
