The Captcha problem on Brave Search is my biggest annoyance with the service right now. With the US servers I notice it seems to depend on location, and the Chicago servers, which the app often picks as the fastest for me, which is particularly frustrating.
I already use Librewolf. I meant the Brave search engine, not the browser. I prefer Brave Search for search engine because I don't want just Google/Bing in another supposedly more private wrapper (Startpage/DDG) and I am not interested in hosting my own SearX instance.
There are no perfect options but it's hard to agree with a supposedly private search engine that is actively hostile to people who are using VPNs (the same target audience!)
