Hello: I'm not certain if this question comes under Firefox or not: How do you stop a specific computer software program-app pop-up notification (popping out from the lower right corner of your computer)? As an example, I have a utility program, IOBIT Malware System Care that pops-up various notifications such as "update notice," "renew," "discount sale" or whatever notice or ads that is 'pushed'. -I went to my Windows 11 list of installed app "notifications" and this program is not listed. -I tried contacting tech support but they haven't responded. -I went to Firefox 'Settings' -> Privacy & Security->Permissions and then I opened up 'Exceptions' to see if I can block something. It wants me to put in a specific website. The issue is not a website but coming within a software / app program. So how and where do I stop a "pushed' notification? I assume it's coming in via my browser / Firefox? Thank you in advance, Steven
