There’s an intermittent glitch causing 403 errors when browsing with Orbot full “VPN” mode, and putting ordinary English word searches in the URL line. With more browsers than just Privacy Browser. Also seeing it on desktop Tor Browser. Almost like Mojeek is blocking some Tor nodes. Going to Mojeek home, then searching, usually is a workaround. DuckDuckGo has a similar “problem with your exit node” stuff too, but less often.
It’s interesting trying out different search sites. Rather than just picking one default in a browser, an option to rotate between selected search sites would be cool.
