A few weeks ago I tried installing a Pi-Hole (hardware-based network level ad blocker), removed it shortly thereafter. Since then, I've been getting the "Our systems have detected unusual traffic from your computer network" screen whenever performing a Google search from Firefox in Private mode, either from the toolbar or from the website. It only happens on Firefox (nothing from Chrome incognito windows), only happens in Private windows, and recurs every hour or so within the same open private window.
I've tried everything to reset my system to baseline to root out the issue, but I'm getting nowhere. Things that haven't worked:
- setting all VPN and proxy settings to off
- ensured all DNS settings are set to automatic
- renewing IP (IPv4 and IPv6, via command window and leaving router/modem unplugged overnight and verifying new dynamic IP assigned)
- clearing all browser data (cache, history, cookies)
- disabling all extensions (Ad Block Plus is my only extension)
- refreshing Firefox (about:support > refresh Firefox...)
- hard router reset
- different network device
- multiple malware scans (all clean)
Is there anything specific to Firefox and how it handles Private connections that might be throwing a wrench here? I'm pulling my hair out.
