With Google selected as the default search engine if I enter any search term into the address bar I get: 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. Why did this happen? I'm then presented with a captcha. A serious PITA! Note that any proper address is evaluated properly. Strangely enough if within a few seconds I enter the same term into the Chrome browser I get the expected number of results. I can of course get around this by changing the default search engine but I'm wondering why Chrome works but Firefox doesn't. Win11 Home 23H2, all the latest Update fixes, latest Firefox and Chrome just checked - seems to only happen with Windows, my Android phone doesn't have the problem...go figure
