So I have the Windscribe Extension installed on Firefox. The free version has 2 GB for free.

After the extension activates, I mean connects to a location, and I visit malicious sites that are included in Bitdefender's database, Bitdefender doesn't block them. It's bypassing Bitdefender's web protection. After closing the VPN connection, Bitdefender is able to block. Just for testing, I tried the same on Avast Free AV, and it doesn't have this issue.
Product: Bitdefender Total Security latest version
OS: Windows 11 Pro
Browser: Firefox
