Firefox Community Forum

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.

I have used Firefox for ages now and love it. I have noticed in the last few months that some functions on some web sites are not able to be accessed. Such as submit, place an order, and the like. I have to use another browser. Is there any reason for this as I really don't like to use any other browser other than Firefox but it seems to be that I have to. Is there some way that I can get around this?

I am confused, because I have been unable to access google drive and Gmail, for a while now because every time I go to the website it says we have detected a problem with your cookie settings, I have tried default settings, and entering safe mode on Firefox, but neither worked. I would much appreciate assistance.

I cannot access certain sites, especially those with "book" in the address. Tried almost every idea presented on line with Firefox browser on Windows 11. What is the answer? Thanks

I have used Tesco.com for online ordering, every week for many years, now the response is access denied. Thank you. TC

Hello! For quite some time now, I have not been able to get into a supplement site that I use frequently. I either have to call them directly or use a library computer, which is inconvenient in both cases. I put in the URL in various configurations but vimergy.com was all that was needed previously. And absolutely nothing happens --- blank page stays blank.

Any help you can give will be greatly appreciated! It just seems to be blocked and in all my searches, I haven't found the answer for how to unblock it.

THANKS!

I could not join a Google Meet meeting today with either an old or new Google Meet url. I don't have a problem with other sites. What could be wrong? Could Firefox be blocking it?
