@nixCraft What’s needed:
1. Up to date software on your device
2. Using only trustworthy browser extensions
When browsing HTTPS sites a VPN shouldn’t even do much, if the HTTPS certificate tells you that it’s all safe and your software is up to date, then it is, the chain of trust is in the certificate system.
VPN also only helps if you use it to connect to a more trustworthy environment than your current one.
Adblockers are not focused on improving security. Don’t install random extensions.
