These icons appeared recently in my Firefox browser I can't remove them. The only recent changes included uninstalling SuperAntiSpyware after finding that Microsoft PC Manager is a better option, which has performed excellently without issues.
Additionally, a free VPN (Proton) was briefly used from the Firefox browser without installation, but after finding it complicated to set up, it was deleted. A few hours later, I noticed the two icons as the windows were misbehaving and they are causing a slowdown in the PC's performance. They do not seem to be add-ons or extensions.
How do I remove the icons and return to the previous performance?
