Firefox ? Chrome ? Brave ?
Kinda worried because all of them try to collect information about your activities online. I've purchased BitDefender AntiVirus, and taken some other precautions but... can never be too careful as they say.
Firstly, you need to be careful with the kind or types of antiviru apps that you install to your pc. No laptop needs anti virus, all you have to do is activate and switch your laptop inbuilt Windows Defender to keep you secured always. If you insist on anti virus, you can download antivirus browser app for usage.
Secondly, you can use any browser with a metamask extension app without restrictions, the only precaution you need to take is to not open phish webpage on those browsers. Remember never to store seed phrases on your emails or laptop cloud.
