Every time I open gmail I have TONS of promotions, please show me how to stop this. It is a major nuisance. Thank you.

And why is Mozilla here? GMail is service of Google, go to Google for support.

You posted in the Firefox support fora queue. Firefox doesn't do email, it's strictly a web browser.

If you are using Firefox to access your mail, you are using "web-mail" such as Yahoo!Mail or Gmail. You need to seek support from your service provider or a forum for that service.

If your problem is with Thunderbird, let us know and we can move this thread to the Thunderbird support queue.
