Firefox and Google Recaptcha

I recently switched ISP and now when I try to google anything with firefox I keep getting this message appear:

"Our systems have detected unusual traffic from your computer network. This page checks to see if it's really you sending the requests, and not a robot."

It prompts me to click 'I am not a robot' then pick out which lights have cars etc in them. Worked fine before the ISP change. Some notes:

- This does not occur on Microsoft Edge or Chrome. - The only add on I have is Ublock but it still does this when I have that disabled. Plus I have Ublock on Edge and there are no issues.

If it's my IP address, then why does this ONLY appear when I use Firefox? Surely it would also appear when using google on any browser if my IP address was in question...

From what I am reading online, my only option is to either: - Use a different search engine ; or - Use a different browser.

I'm curious to hear other people's thoughts on this.

You can check the connection settings in case you use a Proxy or VPN service.

  • Settings -> General -> Network: Connection -> Settings

If you do not need to use a Proxy to connect to internet, select "No Proxy" if "Use the system proxy settings" or one of the others do not work properly.

See "Firefox connection settings":

Does it still happen in Troubleshoot Mode?

Thank you for the responses. For reference, a couple of days ago I had selected 'No Proxy' in:

Settings -> General -> Network: Connection -> Settings

I haven't seen a single recaptcha page since. Thank you.
