I found the GoLogin browser on the Internet and am thinking of downloading it. Can you tell me if it is worth downloading? Is it really as effective as they write about it on the Internet?

I think that you should not believe everything that is written on the Internet. Before downloading, you should check the capabilities of a tool yourself, and only then draw conclusions whether it is really effective or not. Or if you like to first get the opinion of people from the Internet, then read not just information on the Internet, but reviews that are written by real people. For example, here is such a review about the GoLogin browser here https://cross-browser.org/reviews/gologin/ .
