For the cleanest setup, especially if you’re working on Kali Linux or other penetration testing distributions, consider creating a specifically for security testing. This keeps your testing extensions isolated from your everyday browsing, reduces accidental permission sprawl, and maintains better security hygiene.
While not a technical vulnerability in the software, v2.9.x risks encouraging "script-kiddie" behavior.
