hello, you have various malicious addons present. please try these steps:

1. reset firefox (this will keep your bookmarks and passwords)
2. afterwards go to the firefox menu > addons > extensions and in case there are still extensions listed there, disable them.
3. finally run a full scan of your system with different security tools like the free version of malwarebytes and adwcleaner to make sure that adware isn't present in other places of your system as well.

Troubleshoot Firefox issues caused by malware

If you get a pop-up message asking to update Firefox or plugins then such a message is likely a scam and you should never respond to such an alert to avoid getting infected with malware.

• Only update Firefox via "Help > About" or by downloading and installing Firefox from the Mozilla server and never via a pop-up or link on a web page.
• Plugins should only be updated via the plugin itself or by visiting the home page of the plugin.

i reset firefox but it didn't help and now i'm not only getting that pop up but also web forgery warnings can one of you please stop it cause i am trying to watch something but can't if this keeps happening
