Diễn đàn hỗ trợ Firefox

When signed in Firefox puts popups on the right of the screen that refer to my incoming mail. I end up having to delete them all the time. How can I prevent these popups?

I'm being bombarded by FireFox regarding "Dangerous Files" Downloaded, and I cant find a way to turn them off! I have Malewarebytes installed and I don't need nor desire for FireFox and a number of your PAID advertisers like McAfee, to be involved in my on-line protection. How can I shut down FireFoxs intrusion on my privacy? Browserjmva001

i have a lenovo windows 10 desktop media centre. every time i launch firefox on it is will ask me if i want firefox to start at startup, which i do not want. i have selected no on the push notification, and selected no in the settings yet the next time i open firefox it asks again, it is very annoying and has only been doing so for about 2 weeks
